Rear camber adjustment - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Limsson · 04-27-2015, 02:55 PM

Installed Bc racing coilovers on my car this weekend and now realized that i need some negative camber in the rear to get the wheel inside the fender. Bought som LCA and mounted but got the feeling that i need the toe arm to to get it right. Didn't have much time to adjust it either so thought i ask. the "upside" on the tire needs to get in like an inch and a half to get that clerance.

you're gonna need a lot of negative camber for it to move 1.5"... lol

Depending on which aftermarket LCA's you purchased, you should be able to camber the rim/tire inwards. I personally would hold off on spending more money on the toe arm and see what the alignment shop can do with your current LCA's.

How much camber do you have in the front?!

Ashikabi · 04-27-2015, 04:20 PM

That's a lot of camber bro... Might wanna get some skinnier tires and stretch them for some extra clearance. Be aware, I dropped mine on Stance and my caster is off. Might need adjustable trailing arms if you want it to look perfect

Limsson · 04-27-2015, 04:26 PM

The car is getting an fron alignment next tuesday so i will ask them then about the LCA.

should i mount the "Wheel hub" on the upper hole and the coilover in the lower, difference?

Don't know about the front camber, will do next tuesday

Ashikabi · 04-27-2015, 04:30 PM

Those are some crazy looking arms... the lower holes should get you more drop without adjusting the coils(to maintain travel) I'd imagine bottom hole for coils and top hole for hub will get you the most drop

Limsson · 04-27-2015, 04:33 PM

Crazy looking like shitty perhaps? Got no experience in this... Thanks for answers, will change the hub tomorrow and try to set it up.

Ashikabi · 04-27-2015, 04:40 PM

Not shitty, just never seem one with so many holes. If you are running spacers I'd take em out. Otherwise heavy camber is the only choice with current parts. Skinnier wheels and tires would be the actual way to "fix" the problem but still get it low. Heavy camber will decrease traction and increase tire wear FYI.

Ashikabi · 04-27-2015, 04:50 PM

I'd also like to point out that heavy camber is likely(not positively) to require adjustable toe arms while a heavy drop will likely need adjustable trailing arms to pull the hubs forward(im pretty low and my caster is really bad with non adjustable trailing arms)

Limsson · 04-27-2015, 04:53 PM

Yeah but the start of the whole problem is that i had the rims with new kumho ecsta tires on but in 5/114,3 from my nissan s14 trackcar so i had to put some 1" spacer to make the 5/100 to 5/114,3... on the gt86. if it doesnt work i have to buy some other Wheels that fit better

thanks!

You may spend that much getting these to work...

Ashikabi · 04-27-2015, 04:56 PM

Yeah there is the problem... You could swap hubs for a 114.3 then you won't need spacers I guess. CJD is probably right. Making these work won't be cheap under any circumstances. New arms, new wheels, new hubs, 10 visits to the alignment shop... whichever one you go with it'll be pricey. Or you can be a baller and just do all of them

adamg · 04-27-2015, 05:09 PM

just do a size or two smaller tire in the rear and add -3 or so degrees of camber and youll be perfect
