Wheels
The answer is PCD 5X100, offset 42 to 52 (48 recommended/std), centre bore 56.1mm. The trouble is with the Brembo brakes on an STi you only have a limited number of wheels which fit over the brakes - These include certain OZ's, Speedline Turini's 18 inch, some of the the seven spoke WR1 replica's that are available and the Roto wheels, there are an extensive range of these, in 17 inch they have Boost, Grid, SDR, Torque & Tarmac II in 18 inch formula mesh and Tarmac II. See www.subydude.com for pictures and a fitment chart. These wheels are available in the UK from sales@rims.co.uk

It's not the off-set that is most critical, but the clearance behind the spokes - those calipers are huge. There are easier and better ways to improve the brakes IMHO. Contact Godspeed.

As Hoppy says, it's not the offset that will give you a measure of caliper clearance, it's down to the shape of the spoke. Depending on which model you have, you may find the easiest solution is to use the std STi 17" wheels unless you can fit an 18" and then the choices get much larger.
As an example, the std STi wheel is ET53 and our P-WRC wheel in 17" is ET52 but it doesn't fit the Brembo's, you would have to go to ET40. The 18" is ET53 for WRX but this doesn't fit either, we have it in ET46 to fit an STi. The P-FF7 was designed around the brake and as a result we could actually fit over the brakes at ET55 although ET51 gives the best packaging space.
Hope this helps

Thanks for the reply's,
I have an STI7 but I'm selling the brakes as I have a set of Ap 6pots to go on and everyone is asking what wheels they will fit under (Olly being one of them), which I can't answer. So is there a quick way of finding out if a set of wheels are compatable?

Scotty, keep the STi brakes and refit when you sell the car. Then sell the APs, which always fetch good S/H prices. Just a thought.

with the money I've spent on the AP's and other bits I can't afford to leave the Brembo's sitting in the garage otherwise the wifes going to start asking questions about where all the money is going.
So calm down Olly they are for sale.
