Fitting 15x8 challengers with rx7 brakes

[Nic19]

Hey guys. I just test fitted some 15x8 -9 challengers on my rolla. They foul on the brakes tho. I don't really wanna run spacers tho cos I already have sigma arms. Has anyone else has any problems like this? And how did you het around it. Or did you just use spacers?

XT130 arms, camber tops and spacers. Or 16" wheels.

i can say this for you now. they wont fit. the design on the back facing is for old school cars with flat or drum brakes. so without spacers they will not fit, and since the back face is flat you have to run very large bolt-on spacers, or long studs and slip ons.

they are sick rims but you will find it very hard to fit them if at all.

they will fit with 8mm spacers but dont wanna run spacer!
i think i will just get 15x8 -4 superlites, this way i wont need a 5mm spacer and little less offset than challengers so hopefully minimal guard mods compared to wats there now

where are they hitting the caliper. you can grind off the lug that is in the middle of the calipers.

it fouls the whole caliper cos of how big the mounting face is on the back of the challengers

You cant grind that lug off, it has a gallery underneath and youll expose it.

FWIW, there are some RX7 setups where you can mount the caliper under Challenger/flat brake style wheels:

Just in that gap between the caliper and the wheel section you can see the hub poking out. Caliper sits proud of the hub by 3-4mm.

I started a thread a while back about which wheels clear 4 piston brakes, there was some good info in there, Ill try and find it. I had the same issues with Wilwood brakes on my setup.
