Hey guys, I'm trying to find out what all I may be missing to get this 240 set up for autocross.
So far this car has sr20 swap, gt2871r turbo, 550cc injectors at 18 psi, turbo back exhaust with enthalpy ecu. Suspension wise I have agx struts with swift springs, adjustable rear camber kit, adjustable toe arm, adjustable tension rods, just ordered front and rear sway bars, 5 lug swap, z32 brakes, j30 diff. My tires are currently shit but size wise they are 235/45/17 in the rear 225/45/17 front.
What would you suggest my next step be? I know I need tires. But I figure its best I learn the car on junk tires before upgrading. When changing my tires, should I stick with my current tire size or go with a different size? If I need a bigger size then I'll also need spacers since they currently barely rub the strut tower.
