Ok this is a good news, bad news, great news story. First the install ended up taking MUCH longer than expected. I must admit I was surprised by the original quote of $350 and actually had expected higher. The total ended up being $500. I'll eloborate more in a minute but stay with me here. If all you care about is the handling then jump to the last 2 paragraphs.
The KW V2's were installed, as well as the Hotchkis Sways. I asked for a drop of 1/2" figuring another 1/2" from natural settle over time as everyone stated. I'm not looking to lay my 300C on the ground or anything just a little better stance. All four shocks were turned to their firmest setting and then backed off 1.5 turns. Since I was getting all this done I figured that I may as well just balance all 4 tires for good measure.
The tech's had a very hard time getting the stance right and ended up dropping the rear cradle 3 times to adjust. Not fun for them and the man hours added up. Ultimately the ride height is perfect and the handling, well more on that in a minute.
Now back to the price. The quote with the road force balancing was actually closer to $400. When I called to ensure that the car was ready today they drop the bomb that it's $500. Having met Dave at the M&G about 2 months ago I knew these guys gave the best estimate they could and did the best job possible. So I knew even before the call that A) it would cost more and B) as long as it was within $150 (or roughly 2 more man hours) I wasn't going to get upset. Now for the best part. When balancing the wheels, the weights had to be moved of course. The wheel weight adhesive somehow marred the wheel. Dave ordered two brand new wheels under warranty. Nice.
But what about the handling? Finally I got to take my baby home and luckily the predicted thunderstorms were nowhere to be seen. As I turned onto the freeway on ramp I threw her into the 35mph suggested turn at roughly 65mph. Where it normally would've fallen over slightly and ESP stepped in, it tracked flat and true with no squealing tires. So now I know it's got more. I then proceeded to the clover leaf and proceeded to raise the speed in 5 mph increments until ESP decided enough was enough. On the 5 try I got up to 80 mph and she started a nice 4 wheel drift and I believe ESP kicked in, but honestly couldn't tell. This is the best and most comfortable I've felt with the handling to date.
The ride is nearly unchanged until you go over a speed bump. I was expecting a little better "landing" but it literally crashed over the bump. Must remember to take those VERY slowly now. The highway ride is fine, somewhat firmer but not racecar firm. Still better than my CTS-V. What would I change? I should've dropped the rear 1" vs. 1/2" right out of the gate. Unfortunately to adjust that now would take another cradle drop, I'll wait to do that. 1 and a half turns off full firm may be a little much for some. I think the advise of 1 off the front and 2 off the back would've been ideal. I shared this warts and all so everyone could hopefully learn a little something. I know I did. The best part was I now have a service team I can trust, a car with much improved handling vs. stock and two new rims on the way!
