Ok here is my setup, tokico illums, sprint springs, neuspeed and pilot front uppper STB, pilot upper and lower STB. Even if I set my tokicos at 1 (front) and my rear at 5, I still get mad understeer? What else can I do to try to combat this problem?

You can add a thicker rear sway bar and keep the stock front to give the car a more neutral feeling and help combat the understeer issue. Only down side is with a set-up like that suddenly letting off the throttle may cause the rear to kick out while cornering.

check your tires. make sure they're a decent tire with a good amount of tread left. if that's good than you can adjust your air pressure so your rears are about equal to the fronts if not higher. you appear to be on custom wheels so i would recomend your pressures be at about 34 even or 34F 32R for normal driving and if your going to compensate for understeer try 32F 36R

thanks beefgg for the sig

After i installed the RMDSM sway bars, all of the understeer was gone. I didn't have a problem with oversteer afterwards either. The car is pretty much neutral. If i do end up breaking it loose, which isn't often, the whole car will slide but it's easy to regain.

Yea I have brand new 225.50zr16's, on momo 16*8 wheels, so the tires are good, (in fact they are almost "r" rated). Where do I get these sway bars from?????
