i think they do. i want my car to not lean like a b*tch everytime i turn, i got pro kits, my car is the only SOHC that is all stock no internals, just a cx with a d16z6 si, headers intake, custom 2 1/2 pip to greedy exhaust( i know i spelt it wrong) and 15's acura rims. my car runs a 15.3 1/4mile at 92mph. the closest i seen is 15.5.
i thought factory sway bar would be a good upgrade, to start and see how much more i would need instead of jumping to a aftermarket. i think i might get those bullet aluminum rear LCA's they have the hole and lighter and stronger, i also just bought a rear tie bar, do you think i will notice the diffrence and what do you think will be most noticable
