RCE Tarmac 2/17x9 RPF1 Clearance?
 

Hi Everyone,


Recently installed RCE Tarmac 2 coils and I am looking to get into a lighter/wider wheel and was hoping to get some input on the tire/wheel clearance for the following.


RCE Tarmac 2 (Raceseng Cascam Top Mounts)
17x9 Enkei RPF1 +45mm Offset
245/40/17 DOT Tire (Likely an RS4 or something along those lines)


Installation wise, the car has a crash bolt installed up front from prior classing and since the top hole of the strut mount on the tarmac is slotted I will be maxing out the static camber via that, and then adding additional camber via the top mounts to achieve necessary track oriented camber. I am looking to achieve the following alignment/ride height with adequate strut/tire clearance.


Camber F : -3.5'
Toe F : 0" Total

Camber R : -2.2'
Toe Rear : 1/16" Total

Caster F : 7.0'


Ride Height : Approx 13.56" from top of fender to center of wheel hub. Slight rake with the rear being a 1/16" higher than the front. Car will be corner balanced so static corner heights may change slightly.


Thanks for the help!

Clearance to the strut should be no problem, neither should the targeted camber, I have rubbing on the inner fender liner with those wheels so I use a 5mm spacer with extended studs to prevent that from happening. +35 to +40 is no issue, might be able to get away with a 2-3mm spacer to prevent rubbing, not sure. Edit: +35 has no rubs on the fenders unless you go low enough for any tire to rub.

Fantastic man thanks, that's what I was looking to hear. Can you advise where or how you heard about the +35 having no issues at this measurements?

If you're going for as much as -3.5º of front camber, you'll probably prefer +35 offset over +45, as +45 will be too deep in the arches.
