Does anybody have any ideas on changing stock upper a arms (or spindles or lower a's) to improve the front end geometry on a metric? I cut the upper mounts loose to try to help my caster/camber settings and to try to put bearing end shocks down through the springs in the stock location. It looks possible on the right side, and twisting the upper mount took some caster change out of it, but the left side is another story. The left side looks like it wants a longer upper a (like off a camaro or metric impala) to get the shock clearance, and the bigger a frames want a bigger/higher mount. I'm about to get in way over my head, not sure whether I'm helping or about to reeeally hurt myself... Thanks.

Don't know if I can help, cuz I don't know what rules you have at your track. I have an I-Stock (OLDS Cutlass). I have found that if you need more than 3-4 degrees camber in your right front, the handle problem is elsewhere, such as springs/shock combo, stagger or even driving style. To me metric cars are naturally tight. JR Motorsports has adjustable upper A arms, you could try those, also you can try a raised upper ball joint.

Rules say that you have to use "stock " suspension (no aftermarket a frames or mounts) and that you can use "racing shocks in the stock location" (the promoter said bearing end shocks would be ok as long as they went down through the springs). I used 3 camber and 4 caster on the right last year with 2 camber/3caster on the left, stock mount shocks, stock metric a frames and mounts in the stock locations. The car was basically fine, I'm just trying to improve things ( get the right upper a out of the exhaust, use the better shocks) but not sure what all geometry changes if we use a longer upper (like off a Camaro or an Impala) and the taller mount that goes with it on the left or both sides.

What about using 2 left side upper arms?It helps your caster and camber.We use a left on the rs and it ends up using less shims to get it correct.Or try using an offset control arm shaft.

i agree with atomic stock metric parts is a good combo for setup maybe not strength (ways around that) I would look elsewhere for problems

bluedog 17, it sounds like you are over your head. These kind of mod's require knowing exactly what you are doing and what you are trying to accomplish. It can be very difficult to explain over the "e" waves. If you have a very trusted friend that knows what they are doing then modifications can be done successfully and with good results. But really, stock stuff ain't that bad, and if you play around with adjustments you just might find the improvements you're looking for. If you are set on exploring new avenues, try bolt on stuff, like Nova lowers, or Impala spindles and see if you like them better, BEFORE cutting and relocating mounting brackets. I recommend maximumizing your set up for the whole car first.

Thanks everyone for your posts. Not sure what I'm going to do yet, kinda putting off welding anything to think about it a little more....may just weld the stock mounts back in the stock location, use the stock mount shocks, and let 'er eat. Anyway, thanks again for your posts!
