FE5 arms - increase castor a smidge, which will help as well, and these are stiffer with less front to rear flex to reduce wheel hop AND they're 25% (2.2 lbs) lighter.
Try that setup with -3* and I bet you change your mind.  That's my plan, but on 245/40/17 Star Specs (245/45/16 if they'll fit over upgraded calipers/rotors) for STX. That plus slicks in DSP = woohoo!  Of course, you know your shit too, so I am curious to see your results as well.  |
oh and for wheel hop, while surely better control arms can help, the root cause is the impossible angle from the output shaft of the transmission to the center line of the front hub; GM latest information suggests that assymetrically stiffer axle shafts will help reduce hop ( I guess that means buying one stage 2 shaft off the aftermarket if you believe that) but the GM build book says rotate the motor and thats been my experience . I have done the rotation both with UHMW (works but vibration is awful) or with shims, stock rear mount and revised front mount with a UHMW offest bushing with a smaller rubber joint...both methods work 100% i settled for no vibration...
