15x7.5 5x114.3 wheels?

I've done all the searching that I can take - I give up. Does anyone know of any 15x7.5" wheels in 5x114.3 bolt pattern? I need a set for my GTUs project. Ideal offset is probably in the 30-35 range.

I know about Rota Slipstreams. I am not a huge fan of Rota wheels.

I contacted Keizer and Kodiak and it's going to be between $350 and $500 a wheel to get them custom made. They'll be light, but I'm curious if anyone has heard of any other options.

Thanks!

John

DO NOT GET THE SLIPSTREAMS. I got some 15x8's and they had a critical design flaw in them and I have to believe that the 15x7.5's do too, since they don't normally do Slipstreams in that bolt pattern. See here: https://www.rx7club.com/race-car-tech-103/affordable-15x8-fc-track-autocross-wheels-available-now-614462/

I'm now using Kodiaks and they were expensive, but they're way nicer and I'm sure I'll get many years of use out of them.

Yes, I've seen that thread, hence why I said I'm not a fan.

For my racing class the maximum wheel width is 7.5" Yes, it would be GREAT if I could use an 8" wide wheel. But I can't.

You may be able to find some muscle car type wheels in an appropriate size, but they'll probably be on the heavy side and you'll need to watch out for the drag racing only ones (read: no cornering loads).

I know it's not a 15x7.5, but there's always the V6 Mustang wheels from about 94-04 that are 15x7, 24mm offset and I think they're not too terribly heavy (maybe in the 15lb range). It might be cheaper to get those, then get them widened by 1/2" (no idea how much that costs), which would make them 15x7.5, 36.7mm offset (since they add to the inside of the wheel).

The wheels must be 15 x 7.5. There is no way around this. Not interested in heavy wheels. The Keizers are the benchmark - about 9-10lbs each and $350 apiece.

I'm really just asking if anyone knows of any comparable wheels that are less expensive even if they are 2-3lbs heavier. I just have not been able to find anything.

Another place to try is Bogart. I seem to recall that quite a number of Miata autocrossers tried their wheels when the new 275/35/15 Hoosiers came out. I've not heard a lot of charitable things said of Keizers, the Formula SAE team at the university that I graduated from had them and didn't like them.

Centerline Wheels makes a number of 15x7.5 wheels (e.g. Convo Pro) that are quite light. I think they're primarily drag wheels, so you'd have to inquire about the suitability for side loads. Centerline Wheels Summit Racing also carry them.

To further this discussion, I have inquiries out to Tire Rack to see about both the Kosei K1 and TR Motorsport (house wheel) C1 being available in 15x8 5x114.3. I've heard anecdotal evidence that they sometimes provide those wheels in custom patterns, or even undrilled. If 15x8 can be made available, I'm sure 15x7.5 can too, so I will report back.

Team Dynamics. I might be able to get you a set of those in what you need.

You can get these BBS RS And order a new inner barrel so it's 0.5" wider. This should net a 30mm offset if I'm correct. Just guessing in my head.
