Default New to forum- Need autocross assistance.

I have a question regarding my next set of tires. I have recently been attending my local autocross events and I am really enjoying it. I've been wondering if I should be running a more sticky tire with my current setup.

I drive a 2013 Subaru STI. Stage 2- Cobb intake, downpipe, invidia q300 exhaust. I also have an accessport with a dyncomp tune (moderate tune for Arizona heat)

I've got K-sport coilovers with whiteline 22Front/24Rear swaybars.

I've got G2 Nitto's NT555 Tires 245/40/18

I've recently added -2.5 front camber.

They currently have me running in "SM" autocross class. Any general recommendation on tires/setup would be appreciated. Thanks in advance for reading my post!

I would have thought you would be in STU, with that list, unless I missed something.

You're already deep into STU. Since you're not winning, nobody will care. If you do win, you'll see protests as far as the eye can see. If you want to downgrade, pull off all the stuff you've added to the car and look at good shocks and the best tires that meet the treadwear limits.

Otherwise, I'd stick with everything as it is and just get in seat time.
