I noticed in your sig you have 275s on stock suspension with lower springs. Did you have to roll your fenders? what camber do you run with your camber plates? Do you have an rubbing on the spring perch or fender? Also, do you run track tires at track? If so, which ones? Thanks.
Front camber is negative 2.4, rear neg 1.5.
Factory camber setting (eccentric bolt) up front has to be set to it most minimum settings in order to allow for tire clearance otherwise the tire would touch the strut.
The front tires do rub the plastic wheel well liner but only when turning to full lock; some trimming is needed in there but easy to do, just note the rub marks on the plastic parts and cut away with a dremel or something. Or you can do it the lazy way and let the tire just rub it and/or not turn the steering to 100% full lock.
The tires do not rub the fenders anywhere.
I just ordered some Toyo RA-1's for the track, 255/40/17.

what brake set up do you use on the track? Pads, cooling? The DS2500s I put on the front are much better than stock but I still get fade (yes, I know how to brake properly). Guess I need to go with dedicated track pads.

I run cobalt friction XR2 fronts and carbo tech XP8. I have a bunch of brake checking (over their most efficent temps) on the rears, but nothing dangerous. My fronts look good. The XR2s are great pads. I highly recommend them. Their operating ranges is between 50-1600 degrees. They aren't nearly as loud as the carbotech XP12s I have run. I will switch to XR3 from cobalt friction in the rear once my rear pads are done.
If you don't mind loud I have some front XP12s for sale. They have seen one track day. I will let them go for $175. They are around $275 for the fronts new.
edit:
i run 255 RA1's on fnorcs and do 1:29-1:31 laps at PIR with chicane. I find these brakes are just about right. I might get a little more aggressive next year as a I get some brake fade with the XR2/XP8 combo. I think I might try XR1/XP10 or XR1/XR2 next year.

The latest iteration of the highly successful XP™ series of compounds with an extremely high initial bite, torque and fade resistance than compound XP10™. XP12™ is a world leading friction compound that is unmatched as a Ceramic racing compound, with a temperature range of 250°F to 2000°F+. The XP12™ still has that excellent Carbotech release and modulation that has made all other Carbotech compounds so successful. The XP12™ is the most rotor aggressive compound Carbotech offers, but compared to the competition the XP12™ is still very rotor friendly and contains 100% non-corrosive dust. XP12™ is recommended only for expert/very advanced drivers. XP12™ is found to be most affective on race cars weighing 2,400lbs or more using R-Compound tires; or street cars weighing 3,200lbs or more for track use only. Ideal for LMP1, LMP2, DP, T1, T2, T3, H1, H2, GT1, GT2, GT3, TC, GT, ST, GS, MX-5 Cup, etc… XP12™ is NOT recommended for use as a daily driven street pad due to possible elevated levels of dust and noise.

I currently use a pad compound supplied to me from Scott Adare (http://adaremotorsports.com/) . This is a custom compound he has made to his specifications. This pad is similar to PFC 97/01’s in performance. The PFC was my favorite pad until trying the Adare pads.
For rotors I now use Stoptech two piece rotors and I do plan to add cooling ducts this winter. You can use one piece rotors very effectively but they are not cheap as I’m sure you know.
The 2500's are great for the street and rainy track days. I had great success with the DS3000 pads, dedicated race pad. Night and day difference between the two.
Last season I ran the Porterfield R4s. They worked ok. The problem I had with them was if you mixed them with the stock pads on the same rotor, they ended up chattering real bad. Also they were extremly noisy. On the plus side, they never faded and were easy on the rotors. I still have the fronts that only have two track days on them, if anyone wants them (for a small fee).
This season I've been using the PFC 97s. Out of all the pads I've used over the years. These have been the best. Zero fade, easy on rotors, little dust, and low to zero noise. Keep in mind thought, that I run a dedicated set of Stoptech rotors, just on the track. I change out the pads and rotors on the front and just the pads on the rear, every track day.
