Let me explain my situation - i'm curious as to what others are thinking.



I have a BRZ with:

RCE Tarmac 0’s – setup with 350 rate springs instead of 225/250 (lowered about an inch)
17x8 wheels with Dunlop 245 ZII’s
-1.5 Front , -2.5 Rear Camber
Front Strut Tower Brace

I’ve been doing some HPDE and AutoX events, and on the HPDE events, the car is amazing as is. Very confident and safe. Borderline understeer in some situations, but at higher speeds it’s just fine.


However, in AutoX – I understeer like Mad. Probably due to the tower brace, but it like the other characteristics is gives the car, so I want to keep it.

So my question is – what size / type of sway bar should I be looking at? Should I do front and rear, or just do a slightly larger than stock rear (16mm or so)?



Any input from you guys below would be great! (Since I've done business with all of you )


@Racecomp Engineering ?
@PERRIN ?
@GrimmSpeed ?
Are you running square spring rates? That alone will induce some understeer. Your alignment should also fix some of the issues as well. Most setups dial in understeer for safety purposes.
