E30 build advice

Hey guys!

I'm currently building an 1985 325 to race next year in GT Challenge, Simply put i'm looking to switch to a bigger wheel as there aren't very many slicks for a 14 inch, and I see the most common size wheel used is a 17 inch. All this being said to do this I will need to switch to a 5 bolt pattern hub, any advice on which 5-bolt pattern hubs to use? and any suggestions on wheel spacing to get the tires away from the car?

Thanks a ton!
Harland

Re: E30 build advice

You have two main choices.

15" wheels with a 205/50 or a 225/45

17" wheel with likely a 225 tire

Either one will work and tires are readily available new. If you want to stick with used tires then 17" may be a better choice.

As for bolt pattern. You can buy 4x100 wheels in either size. If you want to get check 17" wheels then you can swap over everything to E36 (kinda) kinda parts and run 5x120 BMW wheels but the money saved on wheels will be spent on the other parts. If you want to keep things on a budget just buy a set of wide 15" 4x100 wheels.

The slightly smaller diameter also helps with gearing.

Tire rack has a house brand wheel that is quite popular. They make a 15x8 that should fit with stock fenders and fits the E30 hub bore. I have two sets and they are strong and fairly light. One of the best deals for a wide wheel.

Oh, and I may as well say this cause somebody else will. If you want to save money just buy somebody else's race car. Building your own isn't worth it unless you enjoy the process at least as much as the result.

Do a search on Kijiji for the size, you might find something you can use in a pinch:

Re: E30 build advice

These are the wheels I was referring to. A huge amount of E30 track cars on the 15x8 version of these. About $100 a wheel is tough to beat.

Re: E30 build advice

Don't re-invent the wheel so to speak, buy a set of these.

Made to fit your car, most of BMW guys I race with use the E36 adn E46 versions of that wheel.

Re: E30 build advice

I'd say it depends on your budget. Tires are wear items and you're going to be buying lots of them. 17" tires in the proper size for an E30 is going to be expensive. 15" tires are relatively cheap and there's lots of selection so that's what I'm going with for my build.
