15mm is fine. I use them on bbs before and on et25 wheels. Theres not a lot of clearence but enough.

Sorry again guys just a quick one, are the studs on an e21 the same thread as a golf, polo etc? And also will the seats on these bbs's be tapered or radius?

Yes I believe so. M12x1.5 iirc

And what about seating buddy are genuine bbs classes as aftermarket or standard??

Eh? Seating?

Just use stock bolts mate. Itll be cool.

whats the biggest tyres anyones ran with 15" et13 wheels?
as i have a set with 205/50 i havent tried yet,

I mean as in the taper after the hex on the studs, where it actually makes contact with the wheels. Can do some serious damage to the wheels if the wrong ones are used

Yea bbs take a the stock tapered bolt. same as original wheels.

Ahh sweet bud, thanks for your help, from past experience stock is radius, aftermarket is tapered, it's only as I need to get hold of some spacers so obviously longer bolts will be required

Oops that's what I meant. Lol

Haha no worries, so ill need some longer radius bolts to run some spacers then we got there in the end haha

50mm I think . I can measure one. Didn't your car have rims when you got it? Maybe already has spacers n longer bolts?

Well I'm not sure if the wheels on it are standard or not tbh, they could be off an e30 but I'm not sure, and as I haven't seen the car in the flesh I won't know until I get home, and I want to make sure I have spacers there so when I get home I can put my wheels on regardless!!

you need spacers on e30 rims to fit them mate. wait till you get home!

Is there any way I can tell if my wheels are e30 or not?
