Default front upper control arms for camber adjustment

Dear Fellow RCF owners,

Just need some recommendations on any adjustable front control arms that can adjust the camber in the front, as the stock setup is wearing the outside of the front tyres more than the inside. Especially when taken down to a trackday event.

FIGS Engineering makes them, along with some other brands out there.

Figs and T-demand is the only two that makes front UCA.

Rear arms imo not needed unless you want positive camber.
Lower the car and you’ll get negatives camber of like 1-1.5 degrees automatically

so the front will go to 1-1.5 negative camber after lowering yeah? just a bit hard getting in and out of driveways if going lower on the car... hence looking and adjustable arms to dial some cambers on the front..

The front camber don’t drop as much. Can’t remember exactly where they got to after I lowered car. But it wasn’t enough for track use. Had to get UCA to fix. I run like -2.8 degrees now and the tire wear is good on track. But if you drive with that setting on street, gonna have wear on the inside instead.
If you don’t track a lot, I’d say lower the car (if driveway allows) and see go with the slightly lower natural neg camber & go with that for daily.

I am also having excessive outside tire wear, and would like to adjust front camber. Is anyone running the FIGS adjustable front upper control arms with otherwise stock suspension? Any feedback? Thank you!

My T-demand front control arms may be up for sale.
Anyone interested hit me up via pm.
They're working perfectly. I just wanted ones that can be adjusted on the fly.
T-demand ones you have to unbolt from the car to adjust the camber & caster, then reinstall.
For street guys that don’t change camber settings once it’s set, they’re perfectly good.
I want to adjust camber based on which track I go to, so it has been a pain

I’m looking at the Figs UCA as well. With Penske coil overs and .75 front drop only seeing about -1 degree. Would like at least -2 for track use, sometimes more. Rear is -2 with drop. I have the Figs rear arms but can’t go much more as I’m running a 305/35 20 in the rear. There’s a 3 mm spacer just for peace of mind now and I don’t want to run a bigger one.

Raul, I’m thinking about Figs ones. Mike Figs is working on some goodies for me right now. Been thinking about getting his control arms at the same time. Just not so fun to buy the “same” part twice...

kat,
I’m at -2.8 front and -1.8 rear
So much more grip on sweepers but less braking grip on straights though.

Ming,
yes, braking will lose with that much front camber. I’m hoping to keep about -2 unless I’m running a big bank track like Fontana. Braking is paramount on most other road courses. Probably next upgrade will be installing the Figs UCA due to the adjustability you mentioned. I haven’t found another option for the RCF that allow for that quick adjustment.
