Slight front wheel bounce on sharp right turn? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

iceblaze · 04-06-2018, 12:43 AM

Hey all,

I have a 2017 Toyota 86 with Tein Flex Z coilovers, Perrin endlinks, and TRD sway bars. I've also had my cars corner balance/alignment/suspension adjusted professionally. It is lowered a bit. However, I've notice that on some sharp right turns which have a slight bit of downhill grade, my front passenger wheel/suspension feels like it bounces or lumpy once or twice before it corrects itself. It happens whether I accelerate into the corner or not. Does anyone possibly know what this could be/how to correct? Perhaps its just the road thats bad or uneven? Thanks

That would be my guess .......

How much camber?

I've noticed some odd feelings while turning over uneven roads at slow speeds when you start running more than about -2 degrees up front.

Good call.. I'm -1 degrees.. That may have something to do with it, along with the uneven-ness

Nah I'm with hmfrz, you stiffened the cars suspension up quite a bit, more feedback from the road now

If it bounces and oscillates excessively after a bump, that means it needs more damping. The inside (unloaded) wheel should be able to handle a bump without bouncing excessively. Depending on your coilovers, just a few clicks stiffer might do it, but this very much depends on your coilovers and how they adjust.

If setting your coilovers stiffer doesn't help, or makes things worse enough in other ways (too harsh, compromised balance) then you may just have to take a different line through the corner.

I would try your stock front endlinks again. My Perrin endlinks would bind all the time and it made me question why they put a bushing style endlinks on a rotating strut.
