Default Guide to 15" Audi rims that fit over Subaru 4 pot brake

There are very few options for 15" rims that fit over Subaru WRX 4 pots. Most are very expensive rally wheels that cost $300 each or more. This is the way I've gone to get 15" rims over my 4 pots, so i have more options for off-road tyres compared to 16".

1996 -2003 Audi A3, 5x100, R15"x6", ET38 rims with 57.1mm centre bore fit on a Subaru with 4 pot brakes. They're basically WRX rim offset, so sit out wider than the factory Subaru steelies but still sit within the guards.


Image stolen from dirtyimpreza forums and linked at bottom of this post.

Test fitted them on my car and they have heaps of room over the 4 pots.

They're light (5.8kg) and forged alloy - so they will bend and not shatter like most after market alloys.

2 small problems with them- they use a ball seat lug nut (Subaru are cone type), and the Audi center bore is 57.1mm compared to Subaru's 56.1mm. However both problems are easily solved.

The only source of M12x1.25 ball type lug nuts i can find was here:
http://www.otisincla.com/product/B-D...Steel-Cap.html

The alternative is to get cone to ball seat adapter washers. Much cheaper, but i decided to go with the lug nuts. Conversion washers here:
http://vwparts.aircooled.net/Ball-Se...ion-washer.htm

The only source of 56.1mm to 57.1mm hub centric rings i found here:
http://pdt-services.com/en/centric-r...-mm-to-56-1-mm

Post 2003 Audi rims are a different stud pattern. Make sure you get 5x100 Audi wheels! Do not use cone type lug nuts on the ball seat type Audi wheels without the adapter washer.

Will sort out some pictures later.

Cheers,

Rhys

That's awesome, Thanks Venom.
5.8kg is as light as a 15" wheel gets.
Factory alloys are underrated.

They look awesome

Are you getting new rubber or swapping over your Dunlops?

PS: whats the going rate to get tyres swapped over to new rims? I've been quoted $15-20 per tyre!

I paid $25 each balanced. $15 is a steal.

Interesting, I might have to look into this down the track... However I find my breaks adequate at the present time with my power. Plus I have 15's that weigh 26kg each with the tyres.

Sounds about right. Most of that cost is the wheel balancing which you can't really get around because the entire wheel balance changes with a different rim.

Still undecided on tyres. I still think those Kumho's are too big for what i want out of my car.

But soooo awesome! I dont think the size is a prob with the abundant torque you have, but the rubbing is. I wonder if there's anything you can do about it...

A mate of mine used these rims for years on his rally cars, absolutely brilliant rims and generally pretty cheap 2nd hand.

Slight update - Dulagarl found this website which states the 5x100 was used from 1996 - 2003:

Good one!

It also says offset 35 - 45

Instead of getting special wheel nuts or washers (which I'm worried bout being lost) could you machine the wheels to take a tapered lug nut? I dont think too much metal would have to be removed...or is this "dodgy"?
