With the new MFactory LSD installed, my MS6 brake upgrade and my new 275s on 18x10s, I've been itching to flog the car and see how it performs. Here in the South, our autocross season starts in February with our first event being held yesterday.
Forecast Saturday was snow; Sunday was to be sunny and cold. I loaded the car up Saturday morning and threw a tarp over it since it has no side glass. Here's how it looked Sunday at 7:30am - temp 25deg:
The Auto-x was 2hrs NW of my house and reports were that most of the snow fell east of me, so I figured "what the hell" and headed out.
I arrived with a dirty car to find blue skies and no snow.
Between my codriver and I, we got 12 runs on the car as the temp climbed to a high of 35deg. I'll apologize now for the lack of pics and video, but for 6.5hrs we were primarily focused on staying warm and figuring out what was the strange noise coming from the car.
The first 2 or 3 runs provided no meaningful data because the tires were so cold. Once we go a "little" heat into the tires, the car was alot more predictable.
1. The MS6 brakes with HP+ pads are very good. Great initial bite and good pedal feel. Dirty as hell, but they are a track pad.
2. The LSD rocks! No "one wheel peel" as we exited turns.
3. The 275s don't rub in the front.
The bad (or not so good):
1. We began to hear a rubbing noise from the RF wheel every time we turned right. It was the inside top of the wheel rubbing on the knuckle. Normally, there is no relative motion between the wheel and the knuckle - the knuckle moves with the wheel. Upon further inspection, we discovered the bushing in the front-lower-leading control arm was sloopy - allowing the top of the tire to tip inward and rub the knuckle.
2. Rear tires rub just a bit on the fender.
We'll be addressing these issue before the next Auto-x shackdown on 3/3.
