Rear control arms
 

agency power, gt spec, cusco, dme. which one to get. i am hoping for ease of adjustability. I have coilovers on and have 2 degrees of neg camber.

Ease of adjustability go with SPC but if you have 2 degrees on the left and right leave it alone it's fine, if it was bad uneven i would say to change it but you should be ok.

Turn in Concepts has the SPCs and likes them, you can't go wrong with Cusco, the upcoming whitelines look pretty good, and agency power mostly just copies stuff.

And really, how important is "ease of adjustability?" They all work pretty much the same way and it's not going to get done very often.

well i light track duty so being adjustable in the parking lot at an autox event is pretty much a must

How are you going to adjust alignment in the parking lot? You should be able to get a good enough alignment for daily and autox that shouldn't need adjusting.

Are you bringing alignment gear to every auto-x? Chances are you will just make things worse. Adjusting the camber changes the toe too.

it is a balance with tire wear, tread life. the 2 deg of neg camber is not helping for dd. also i used, terribly, the adjustzability in a parking lot as a ease of adjustability example. and i have done alot of suspension work so i know the ups and downs. I am appreciative and thankful for your knowledge. If i dont make sense i blame the excess beer in me now.

must be the beer: You done allotta suspension work so you already know this:

you cant "parking lot change the rear camber" without affecting the rear toe...unless you will have a camber gauge AND a toe protractor, or youre gonna be screwing up thrust line...I dont suggest this on this car, I agree there are some cars you and dial in 'at the track' I suspect this isnt one of them

You don't need alignment gear for a parking lot change. All you need to do is mark the changes when the car is on an alignment rack with a paint pen. 1 color for street settings, and the other for track...

One more mention for billet Whiteline arms.

good point, stand corrected

I just set it for the track, and forget it..

This would be a good time to link a parking lot alignment thread, complete with string.

This x100

The cusco and Whiteline (as it appears) are hard to adjust without dropping the arm at the crossmember point. The subframe covers part of the turn buckle and its hard to get a crescent wrench in there.

The AP is much easily adjustable.

That's very true. It's such a bit*h to adjust them.

I would say to get the one which can be easier to adjust so the alignment shop will not charge you extra to do it.
