FC Adjustable suspension?
I'm prepared to be flamed for having missed this info in a sticky or something. I'm an idiot and couldn't find it, so.....
Friends and I are racing an FC vert in some budget endurance series. We're going to switch coilovers with camber and probably caster adjustment. But I've also been curious about adjustable lower control arms for additional options as we learn about suspension tuning.
Anyone able to point me to aftermarket LCA's for front and/or rear that might allow rear toe, front and rear camber/caster changes? I haven't found anything here, nor much online.
Thanks in advance,
Dave

This link explains the rear suspension on the FC.

For coilovers I recommend Fortune Auto Coilovers. They allow you to request specific spring rates when you have them built.
Most people opt for the S4 front control arms since the ball joints are replaceable unlike the S5. Please note that if you do this you will also need the S4 sway bar end links or opt for Racing Beat Sway Bar End Links. Another alternative is the front control arms from Parts Shop Max, of which I don't have an personal experience with.

Should probably post what your budget is.
Rear toe is mainly changed at the eccentric bolts which connect the rear subframe and rear control arms.
Lowering the rear affects toe (from what I remember, been years since I set my settings). I have battle version rear lateral toe links but they weren’t necessary in setting rear toe as the eccentric bolts did enough to get any settings I wanted.
rear camber is mainly adjusted by the single link which connects chassis to rear subframe. Fine tuning camber on left and right can be adjusted by using adjustable rear camber links (Does AWR racing still make these?) Or you can just make your own camber links (all 3 described)
aftermarket rear control arms are I think non existent. I’ve only met one person who went out of their way to fabricate an entirely different rear subframe/control arm combination, and he was extremely serious about racing and ranted about the lacking of fc rear setup.
Front s4 ball joints can be extended by welding to try to correct scrub radius. Aftermarket front lca are probably out of your budget.
racing beat makes great sway bars which won’t cost you too much.
