13inch Wheel Fitment

[Schniddy]

I bet on 13' being able to fit. There is at least one pair of 13' wheels that will fit on an E30. I'm not sure if they had to do any caliper modifications, but I've read it before on the site. I think Trent used to own them?

Bump. Any progress?

That would make wheel and tire mounted about 31lbs for a 255!

Well then I guess we will see. The linked thread above does NOT show 13" wheels on an E30.....

Guess that's a photoshopped picture.

So what your saying is that if someone has a set of wheels that have X amount of clearance between the caliper and wheel, it's not any concern of yours to help them know what will need to be done to fit your BBK?

If somebody already has wheels and already can measure the gap between their wheels and their stock brakes, what can an electronic profile can do? Nothing. Absolutely nothing. What can help them though, is to download the profiles of the BBKs and test them. What more can I do?

Interesting. How did the guy in the linked post get them to fit?

look closer - he didn't.

1) they are not bolted on to the car
2) they are 4x110 as he notes

[DSP74]

Please, explain to me why I would spend time drawing a profile for stock brakes? I believe you don't get the purpose of such a profile. I don't supply stock brakes nor do I sell wheels. Read your own comment, and you'll see it makes no sense. You want me to supply a profile of a stock system for people who want to upgrade to bigger brakes... Hmmm. Time to have another cup of coffee

Just curious at this point. I still say that even an autox biased E30 needs more tire than the 255 13

[Massive Lee]

I'm surprised someone in your position doesn't have a tech drawing of stock E30 brakes....Should be helpfull I would imagine to answer questions for folks wanting to buy your brake kits. And curious whether your stuff will work with their current wheels.

Have you tried to fit 13" wheels?

Yes I did. 20 years ago. And many tried the same. Don't worry, I am not talking thru my rectum

[DSP74]

He, he. Everybody has tried to fit 13" winter wheels to their e30... 20 years ago. No fit.

Sikboy, you tend to forget that the barrels are not flat cylinders. They are curved-in near the spokes and the diameter can be dramatically reduced, especially near the area where the smaller barrel meets the spoke.

Anyway, good luck with your fitment.

See this. Apparently good luck isn't needed?

That will not lead anywhere to send me a pdf file of the profile as I don't have a tech drawing of the stock e30 brakes. Just buy the wheels and try them. If the wheels indeed fit, you will have owned us. If it doesn't, we will all have a good laugh. :pimp:
