I received my wheels in the mail today, 18x9, +24 offset, Mustang Saleen replicas in 114.3 bolt pattern. After opening the 1st box I was like WOW! The finish is beautiful...glossy black finish. It's almost kind of too nice for a race wheel...lol. After the the wow factory I ran to the scale to see what the weighed. According to my digital scale they are 25lbs. That's the same weight posted on the website I purchased them from. Not the lightest wheel but still 3-4lbs lighter than the factory srt8 wheels. The weight should make this a very sturdy wheel. After all they were designed for Mustangs which are not a light car.

I was unable to mount the wheels on the car because I got home late and wanted to hit the gym. My only worry was if it will clear my huge Stoptech front caliper since from my number crunching earliear in the week I confirmed the offset won't be a issue. I'll have a little more than a 1/3rd of the an inch more clearance than Borbet 18x9.5 +20 wheels at the front spindle. Since I was unable to mount them on the car to test fit I had the next best thing, a template made by Stoptech to check clearance....

Nope, they come right off once they get heated up. At Lime Rock Mike tires were worst and when he got on the track they came off...were all smooth.

your new wheel will not fit. the center hub opening is to small . you will have to take them to a machine shop and get them milled out to the size of our hubs.

woah, this might be an interesting development. I thought with the Cobra rims that we had the same inner hub size. I test fit my Borbets on my buddy's 03 Cobra last night and they snugged up nice on his front hub.

If this is a concern, I'd say bolt one up before you pay to get them mounted and balanced.

I am running saleen wheels 18x10.5 and i had to have the hubs machined out and use 7/16 spacers with longer studs on the front with the 9.5 wheels you may be able to get by with out the spacers.
I also had to find different lug nuts. the Mopar nuts are too big and will not go into the recesed holes in the wheels

Flybyu mentioned this to me when I told him I was buying these wheels. He had the same problem when he purchased saleen replica's in 17" from another source. If they need to be machined I'll take it to a local machine shop. It's very little material that needs to be removed according to Flybyu. He actually said he did his self with sander attachment on a drill.

These are 18x9's, no spacers are needed. I have gorilla lug nuts. They are a lot slimmer than stock and fit in the wheels without issue.

Thanks for the heads up!:thumbs_u:

I was on par with his butt in the corners. He would loose me in the straights because he had more straight line speed and because of my sound decibel handycap. I was all over him in the corners. Go ahead and ask him yourself. Like I said, tires was half my problem.

Don't worry about that bull's eye on your back. It's just me getting my target set and ready to blow by you now...lol:mrgreen:

July 5th at Lime Rock, NO DB limit. Advanced drivers only with NO instructors offered. Gotta pay to play since this is when the big boys come out to run their monsters.

$345 for 3x 30 min sessions between 9:00am and 1:30pm.

By then you'll have my exact tires and have no restriction in your exhaust. Come get some if you want the real crown. I'll be there.

anyone else who is feeling saucy, feel free to pm me for details for the track session. You honestly better be a damn good driver and expect plenty of cars to be faster so get used to point by's.

Yes, I have monsterous Stoptech 6 piston calipers on the front. One ST60 calipers is almost the size of 2 stock brembo calipers put together. The rear I have st40 calipers that are slightly bigger than front stock brembo calipers. I was able to get 17" cobra replica's over the rear big brake kit when I was drag racing. You will have enough room in the wheels to sleep when mounted over stock srt8 brembos.

Very interesting. I'd like to find a rim I can run on the R/T w/o using a spacer. Eneki are the only ones I have found with a +15 and also MB Battles have a +15. I really don't want to pay $300+ for a rim though.

I'm not lysdexic). The bad news is they are $349, but they are an 18x9.5 with a 15 offset albeit 5x114.3.

I really debated holding out on the tire info. I think it's more fun with fairly level competition, at least as far as tires are concerned. There should be some epic days coming up. Our cars will be stressed more than ever before with full slicks and we'll find out pretty quickly what the next weak link is. Hopefully it's not the whole car (finding a wall).

I am pooling my time and scheduling already for next summer Mike and Matt. The wife wants a road trip and i want a battle on away turf. I know every corner of Laguna and i have been dying to get on it in real life for years. I'll be knocking on your doors next summer at a track day. I already have a hitch mount carrier for my tires. The road trip will be EPIC!

You sure they werent feeding you a line to rep their latest and greatest new wheel? According to their site its made with the same process (MAT) and has fewer spokes that are longer then the rpf1s and is even lighter weight.

You sure they werent feeding you a line to rep their latest and greatest new wheel? According to their site its made with the same process (MAT) and has fewer spokes that are longer then the rpf1s and is even lighter weight.

Actually if you look at the side view of those spokes they look quite a bit more beefy than they do in a straight-on view.

Considering who I was talking to and the specifics we were getting into (he was describing why the wheel is stronger in its various points, point by point), I would say very likely he was being straight up. The RPF01 is one of their oldest designs (not a bad thing since it is proven and they got it right the first time -- but one of his points was that wheel engineering has advanced in the time since they were brought out).

Why don't you call him and ask for yourself? He's King Brandt and he's the Sales Manager for Enkei according to his page on LinkedIn. I got the distinct impression that he was a wheel designer himself based on his use of the first person when talking about wheel design, and his general knowledge of the subject.

Net result of that call was that, while he was very confident of a good product that has a lot of racing history behind it (and zero failures that they are aware of), they just don't have any experience with a car this heavy. The PF01 (I guess I are lysdexic after all) is a stiffer, stronger wheel that they seem to have some pretty high hopes for.

What I use is going to depend on offset. The Borbet's are my far-and-away choice. They've got the size and they've got the beef. The Enkei PF01's got a rousing endorsement. You know what I think of the RPF01's. The only thing that worries me about the PF01's is... what if the flex that Enkei told me exists in the RPF01's is actually what saves the rim from destruction, and if I try a stiff, light rim that very trait may be its undoing?

The preference for me is a fat rim for a fat car. The safety margin is where its at.

Im not going to call him, because i'm not going to buy a set of PF01's anyway. I've already spent my money and am happy with the product I've got. I dont expect any problems. I check the wheels for any signs of damage when i check the tire pressures before each session so if a spoke starts to crack or something I'll see it anyway.

Hey Mike, will you bring both the new 9.5 rim and the 8.5 rim on Saturday. I might as well try both options in case the 9.5 is a no go for me. I'm hoping to go at least with a 9".

With your front upper arm, the Mustang rims with a few tweaks might be the best option for the offsets. I'll definitely throw them in the trunk for tomorrow though.

UPDATE!!!!!

The center bore on the Saleen replica wheels were too small. They were 70.8mm and as you know our wheels are 71.5mm. I went to Home Depot and picked up a Drum Sander attachment for a drill, went home and cleaned up the bore till it fit. It took me about 3hrs to complete all 4 wheels. I would take a little off at a time and test fit. I had to do that 15 times per wheel. I wanted to be safe than sorry. Being patient made the wheels turn out perfect. After that I ran to the tire shop to get the tires mounted. I will put them on Sunday to see how the feel on some back roads. I'll also take pics of the clearance to the knuckle as well.

glad you got em mounted, but please don't run those on the street. DON'T DO IT. they pick up EVERYTHING and throw $hit everywhere and will get a puncture extremely easy and then you are out money since you can't patch slicks. You'll fling rocks and gravel from the road everywhere and hurt your car and other cars and people around you.

another reason they dangerously slick until you get them up to temp and on the street you will never get temp up high enough to really grip. my car will spin sidways up to 70 mph when they are cold . I ve seen alot of guys bust their ass in the first turn because the tires were cold.

Boy - The trash talking that is going on here makes me wonder if the HPDE3 run group is safe anymore. If I see the two of you coming at Monticello, I might have to down shift and pull away, but if you did catch me I won't hold you up....but you will have to catch me first. :)

Ordered my rims (Borbets 18 x 9.5 w. 20 mm offset) and got my tires (275/35R18 Hoosiers) coming....it will be a fun day!

Well this is what I found out and will make a seperate post once I get pics. Thanks to Mike for lending me a Borbet 18x9.5 +20 rim. Mounted with a 275/35 tire, I had contact on the knuckle. So this rim will not work on a R/T. The rim itself wasn't making contact, but the tire was.

So he had also dropped off a Borbet 18x8.5 +20 rim. Now THIS rim did work, but it is only 8.5" and I really wanted at least 9". So going by this info and running the calculations, a 18x9 +15 rim will work on the R/T's, problem is that they are hard to find cheaply.
An 18x9.5 +15 rim will work too, but you will need a spacer. Running a spacer with this rim will put the wheel outboard more and I believe it will stick out past the fender.

So either run a 18x9 +15 rim for a R/T or swap the SRT knuckle on a R/T if you want to run something wider.

For those of us with spacers and extended wheel studs, would it have worked? I was thinking a 5mm spacer was what was needed to do the trick. Possibly 8mm.

i got some spacers on the way for some various fitment tests. We can try them out when they come in. I bet a 5mm would get the job done with a 9.5" rim.

I am going to make a "temporary" spacer up and remount the wheels tonight. I'm thinking a 7mm spacer which would be 1/4 inch might do it. Any idea on how much clearance you actually need from the knuckle?

My car sits really low too, but you have the same thing I have, KWV2's so just adjust the fronts, no biggie.

aint no speed bumps at the track, nice and low with a firm suspension will get it done. i'm only 2 inches off the ground running that combo and i didn't drag anything through the downhill compression at Lime Rock park.

I had some touching issues when i was banging over the turn 1 curb at njmp due to the lowness. But my front end is all banged up anyway so who cares.

these are road racing slicks, not drag so they wouldn't be that great for you at the strip. PM me if you still want the info. the sizes we've been enjoying are the 275/35R18's and 280/680R18. If you're into turns on a track, you'll want some of these things for the prices we get.

I think the concern is (and it is for me) is not so much the body but the long tube headers and such. Mine hang low so I will have to adjust for them at the track with the smaller tires.

Yeah the slicks most all of us are running - even though they are different sizes - are 25.5" in diameter. Thats quite a bit shorter as tire diameter goes. You saw how low I was at Big Willow. The thing is though... its not the street. I *did* have a couple contacts at Laguna Seca. Heavy braking and hard turning at the top of the Corkscrew (not in it, approaching it) gave me a sudden thwack. And I had another entering 2 under hard decel.



Any idea on how much clearance you actually need from the knuckle?I get away with a bare finger-width. When the car is on the ground and I stick my hand in and over the tire, I am in full contact with tire, rim and knuckle with my finger... so maybe 3/8" to 1/2" is what I have.

I am running the 280/680/18s and I still scrub my headers from time to time. last year I welded some skid pans on the bottom of my headers which gives some protection . when at Lowes when I bent my shocks It rubbed all the way threw the skid pan & the header .
if you are going to run the 275/35s you might want to consider doing it too.

MattRobertson
05-19-2010, 05:32 PM
those 280's are ideal tires but I don't think I can fit them in the front without new knuckles and 10" rims. But their height and weight capacity is perfect.

With the 26.2" R6's, I never touched bottom... all this is dependent on the car's ride height setting. Me, I'm adding a half inch before it gets back on the track.

glad the few of us with factory SRT headers don't have to deal with that. I know it will be a problem down the road, we are just doing everything we can to keep up with the big dogs.

Ditto...I did my test fit this evening and the car is definitely low with the slicks. By my tape measure the tires are about 25.125" diameter, which puts my rockers about 3" off the ground in front. I may adjust the front up slightly after Friday's 1st test session at Thunderhill. Click on the pics for full size photo's.

They fit in the back of a truck...looking pretty I might add!

You never know... If I want to put in new hubs in the front a new knuckle starts looking even more attractive. I've had my eyes on the 280/680R18 for a *long* time given what it will do for weight capacity and vehicle height.

Well I found out how important it is not to run a directional slick the wrong way. with only three laps my left front tire seperated and nearly blew out. it's my fault. I mounted all four tires the same direction and it was too late to change it when i noticed it. from now on
I will not buy Yokohama race tires because they are directional. I like the option of fliping a tire around if it gets worn more on one side .http://www.lxforums.com/board/picture.php?albumid=1168&pictureid=9521

Joel, cant you still flip the directional tire on the rim and use it on the other side of the car to get more life? You just need to make sure its pointing in the right direction before you put them on the car.

They're directional not asymmetric.

makes sense to me, i wonder as long as there isn't a inside or outside edge if that would matter at all?

joelvan
05-24-2010, 07:23 AM
if you are on a track with 7 right turns & 2 lefts you it will still wear out the left side of the tire regardless to if it's inside or outside of the rim. you will get a third more time if you can use it on both sides of the car before fliping the tire.
