Will ITR brakes clear Enkie RPF1's?

vbspec

Not the 41mm offset..... I know I tried.

huge230

Doh does that mean the 35mm does? was it even close?

vbspec

it was close and i think the 35's do fit but dont take my word for that

huge230

ok thanks. Last question for you. Was it a clearance issue on the front of the caliper or on the top? or both?

Calif_Kid

I'm almost positive that my brakes are ITR with 11" rotors (fastbrake), and my 15x7 RPF1 with 41mm offset clear OK. I do have some small spacers (say 5mm) on the front, but I'm pretty sure that they clear with and without the spacers. The thing is, that stock, they won't clear. When I went from 16x7 wheels to the 15x7 RPF1's, I had Blacktrax handle getting the wheels to fit, and I believe that they had to do some grinding on the calipers. Since the ITR brakes and 15x7 RPF1's are a pretty common combination for racers, I expect that others will reply with more info. Anyway, I believe that ITR brakes will work with the 15x7 RPF1's, but some grinding is needed. - Jim

Thanks! i hope you are right an hope others chime in.

they were too close for comfort on both my +41 and the +35s

Those are ITR brakes? So they did clear but were really really close?

I've test fitted a set of enkei rpf1 15x7 on my civic with ITR calipers and it looked the same as the above pictures. It may have worked with some grinding of the caliper or even a 5mm spacer but I decided to go a different route.

The thing with rim that I noticed is it tapers toward the front face of the rim. If it were the same size the whole way through it wouldn't be a problem, it's the taper that introduces the problem.

MAFDARK

Exactly.


Those calipers were advertised by fastbrakes as Type-R, I have since done the 5-lug swap with (obviously) real type-R components and I must say, the calipers are much larger than those which are pictured above.

Thanks for the comments guys

Anybody actually run them with ITR brakes successfully, via spacers or grinding?

I had to grind my itr calipers to fit under I think +37 or some odd offset I had on the rpf1s

huge230

ok thanks, I will probably give them a try and hope for the best

I now can also confirm that the +41 offset 15X7 RPF1 will not clear ITR brakes.
Now to decide on new wheels or a different brake setup.

The Destroyer

Is it the inner barrel that the caliper doesnt clear or the spokes?

MAFDARK

The barrel of the wheel. About an inch and a half from the spokes the diameter of the barrel reduces by a little more than an inch. This specific part of the wheel is the problem.

The Destroyer

Im aware that the barrel is designed this way, I own a set. Although it looks like it clears the barrels in your pic?

MAFDARK

Correct. You have a clearance approximately the thickness of a business card. That was not enough for me.

As I mentioned, I've got ITR brakes with 15x7 RPF1 (41mm offset), and the wheels clear my calipers with or without my spacers which I just measured at 8mm. As I mentioned previously, Blacktrax had to do some grinding of my calipers to get the RPF1's to fit (with the step down in the barrel causing the issue). I included a few pictures of the right side caliper below - first picture is of the full caliper, and the second the lower part. The grinding is just needed on the outer part of the caliper. If needed, I could get some additional info from the person who did the installation early next week, as they're out of the office this week.

PS - Mafdark is right in that there isn't much clearance between the caliper and the wheel even if you get everything to fit. My clearance is say 1/16-1/8" and a few times on track, I'd had the car pull pretty strongly to the right side. I thought that maybe I had a tire low on pressure or maybe a bad wheel bearing, or something, but I didn't find anything wrong, and the problem cleared up. On the right wheel, I can see some fairly heavy black rubber mark on the inside of the barrel where the step down is, so it looks like maybe some pieces of rubber from the track got jammed in there for a short time causing the pulling. - Jim

^^ that's the only way they will fit unless you bring the offset to some where below +20

The Destroyer

Enkei, not only the cheapest lightest wheel, but also cutting down on unsprung mass in order to use.

damn im bout to get some for my civic to ride on, guess ill be looking for low offset ones.

The Destroyer

Offset wont matter, its the part of the barrell behind the spokes. Get 16's or modify your caliper.

Pic for reference.

slammed_93_hatch

Not true, offset does make a difference.

Moving the hub matting surface close to the center of the wheel gets you away from the raised barrel.

Nothing OTS has a low enough offset to clear but you can just add spacers.
