run a sqaure setup, so you can rotate your wheels.


These cars are heavy, and while they use camber preety well, it does not save the front tires on tight low speed corners.

So was I incorrect in assuming that longer higher speed turns will cause more wear to the outside? Is it the low speed tight turns that will fry your outside tire if taken too fast, as it allows the wall to "roll over"?

.. great I had this great reply written out, and lost the whole thing. fack.


Heavy braking from high speed into a slow, tight corner will always be more abusive to a tire than braking into a medium speed corner.

We're not smart enough to defeat physics yet, so we have to learn some conservation. Easiest way to make the tire last (longer) is to reduce speed, and keep the tire from rolling onto the shoulder as much.

I'm running the stock 18s for track use, not perfect but it works for a leased car. The aftermarkets are for DD. The better track set-up of course might be a square set-up of maybe 18x10 all around. I guess it's just a money thing at the moment. I may be getting NT05s mounted on the 18s considering the performance/cost benefit.

I'm not signed up for AAA with CCA yet, but maybe you've just pushed me over the edge.

Just come out!! It's like our home track.
I'll be at Laguna Seca with the CCA that Monday if you're up for that too.

I don't trust the PS2's on the track anymore. I almost slid off at Willow Springs when I was getting fast on the second day. The fronts got greasy and there was no bite after a few hot laps.
I ran the Vreds at AAA on a much hotter day, and had no issues.

Check out JAJ's tires after a track event with camber plates.

Update.....

I went with Nitto NT05 on the 2 fronts (245/40/18) and left the rear PS2s. The NT05s held up well and performed nicely at AAA Speedway this weekend with even wear. Great value for performance IMO. I didn't get the camber plates installed yet.

I'll run the PS2s on the rear until they're done and then add NT05s there as well. I think the fitment for the rear will have to be 265/35/18.
