I posted this in the tire thread that got moved, so for 1LE owners who don't venture out of this section here it is below:

I took the car out this weekend in show room condition (minus different brake fluid and alignment) just to see where it was at. This car is so incredible in factory form and the tires surpassed my expectations for a street tire. They will be good to go for 95% of owners.


Below is some data from this weekend at Thunderhill West, a relatively short 2 mile course in Northern California. Ambient temps were around 60-70*.

Alignment:
F: -2.4* Camber, 1/16th toe out
R: -1.6* camber, 1/16th toe in

TEMPS after 3rd session:

LF: 156/158/160 RF: 160/161/167
LR: 159/162/162 RR: 158/165/173

Pressures after 3rd session:
LF: 37 RF: 39
LR: 37 RR:38

So you can see that this track is much harder on the right side tires. Towards the end of the day the tires got a little greasy, mid corner and corner exit push increased a lot. You can see by the temps that the car could actually use a bit more camber (you want the middle of the tire to be the hottest), at least at this specific track. Tire pressures were also increasing throughout the day, despite starting at 28 cold. It appears that the tires work better in the 36 range, but don't quote me on that.

I haven't checked tire wear with a gauge, but I noticed the outside of the tire seemed worked, which would make sense looking at the tire temps. I may see if I can get a bit more camber, and also play with temps a bit. Overall really impressed with the car and tires, they will support most owners.

I would highly suggest everyone check their alignment, even if they plan on leaving the factory street specs. My car along with other owners on here have had a factory alignment that was a bit off. I had mix matched camber and toe.
