Upper or lowers first?

That is a very good question! I am about to get the Eibach Pro springs myself and if it causes traction problems with no other mods (other than the springs) I will need to get something to allow for more traction as well. Anyone please help with this dilema?

Not sure if the control arms would give you more traction,they will eliminate wheel hop though. I have the Lca's and on a cold day I'm bouncing off the rev limiter through 1st and 2nd it lights the tires so bad. I do have cheapy rubber though.

Even though I now have both the upper and lower Steeda's I installed the upper first and it eliminated my wheelhop completely.

I would first do the upper followed by the instant center brackets and finally the lowers if you want to go all out.

As far as the upper goes I would go with the Steeda upper over the BMR because it has a pinion snubber on it which the bmr doesn't. You can see the snubber under the poly bushing.There's only a $10.00 difference in price.



As for the instant center brackets I'm probably be going with the CHE Performance ones because they're completely bolt in as opposed to the weld in BMR brackets. CHE is also putting out an upper link with a pinion snubber.

Thump_rrr, glad they worked out for you but the recommendation is backwards.

Lower Control Arms first, followed by the relocation (instant-center) brackets if you want a little more and further adjustability. Switching out the Upper Control Arm is better left to those who need even more bite at the track and want to play with pinion angle.

If you were to use LCA relocation brackets with the stock lowers you are still going to cause them to flex under a lot of load. They are stamped steel arms with weak bushings, this is the major cause of wheelhop on our cars. Fitx that first.
