5mm spacers, longer bolts required?

[Mystikal]

My new wheels are coming and due to the spoke design, they may rub on the caliper despite being ET27. 5mm spacers would fit the bill perfectly, but do I actually need longer bolts to go with them? I have no idea, is 5mm enough to warrant a safety issue with stock bolts? Lastly, would a 5mm spacer (obviously non-hubcentric) cause any sort of issues under extreme load? I'm assuming the ring of the hub would still stick out slightly, but I'm not sure.

Thanks guys.

On my race wheels I have longer studs as I too have 5mm spacers.

the real question is do you want to lose 1/2cm worth of threaded contact between your wheel and hub.


i wouldn't.

Screw it, I'm doing it once and doing it right. RRT stud kit and 5mm (maybe even 8mm) H&R spacers.

Thanks anyways. :P

Edit: Good timing Kris. I was searching on Bfc reading up on what the E36 M3 guys were racing on, seems the RRT kit and H&R spacers are the way to go for hard use.

Stud kits are nice if you have the proper wheel nuts that are shaped for that particular wheel.

make sure the studs will clear the caps for your new wheels. otherwise you'll lose the ability to run the wheel covers.

Good point.

I'm also noticing another problem. The wheels (and the stock baskets, and my winter wheels) all have a beveled mounting surface. Apparently H&R doesn't recommend using 5mm spacers with this style. Odd, they don't have a disclaimer on the 8mm model and that also doesn't have a hubcentric lip.

Help.

Since my 17" wheels and 14" winter alloys have a beveled mounting surface, can hubcentric rings be installed? I'm assuming this is the application of them.
