Roll Center Adjusters...drifter's best friend...

[driiift_hachiroku]

besides an LSD, a Roll Center Adjuster is one of the essential elements to tuning your AE86 suspension.

An RCA goes in between your strut casing and the lower-control arm on the front suspension. It's basically a block that returns your control arms back to "normal" position, instead of parallel to the ground on a lowered car.

There are some Negative Roll Center Adjusters that are set up to add more negative camber and front track width. I installed a BattleVersion NRCA today, and you can really tell the difference.

Problems that it alleviates:

Bumpsteer
Bodyroll
Understeer on turn-in
steering effort

and NRCA's defintely make the AE86 look mean on full DEMONCAMBER setting.

just a question

can any part of the rear suspension be adjusted for alignment?

or is it a total fixed axle?

[goodcookiedrift]

total fixed axel...you could only adjust the lateral rod aka panhard bar so that it tracks evenely on either side....ussually loweirng the car alot warants an adjustable laterla rod...ie: jover and george

ahh ic

every think of those rigs like on them crazy ae86's that are welded onto the diff?

Heaps of stuff are worth adusting at back.
Too bad there are no means to adust them on OEM trim cars. For example altering rear axle support arm geometry would consist of some welding, grinding and accurate drilling.
In racing car suspension one just would undo bolt, shift arm to adjacent fixing position and redo the bolt.

Despite solid rear axle construction in older rwd cars, we can adjust camber and toe-in within very narrow margin.
This coupled with attention to support arm attitudes is worth the effort - in my opinion anyways.
