I have a 03 WRX with
17-7.5 BR with 234/45/17 YOks.
Carbotech front rotors,
Tein springs
Cucso front strut bar
Perrin up/Down Pipe
HKS hiper Ex
K/N drop in
HKS SSBOV
MBC

I have looked at the different classes and have a hard time figuring out exactly which one I would fit into. I realize I should of started out stock then moded but that did not happpen. The car is somewhat modded and either I continue to mod or figure something else out. I would want to install a cusco 22 mm rear sway bar, carbotech front bake pads, endlinks and rear strut bar. But since I dont really know what class I would be in, I do not know what to use parts that would just put me over the edge and into another class. I am new to this so any help would be very useful. Thank you in advance.

 

For SCCA auto-x classing, right now BOV and MBC throw you into SM (and also if you're catless).

Add a cat, remove the MBC and replace the BOV with the stock unit and you can run STX.

Those 4 things are legal in both STX and SM.

Thanks for the info.
