5mm spacers to fit B5 S4 calipers and USP wheels???

**davidlizard** · 06-20-2009 11:05 PM

Can somebody confirm that 5mm is enough yo make my 18" USP clear my B5 S4 front calipers?

simple math, whats the offset of those wheels?

I dont know ET. This set is replica and very similar to OEM. I did'nt see any ET numbers on the wheels...

ET is either 45 or 48 and yes 5mm should be more than enough.

The OEM USP wheels fit without spacers for the b5s4 brakes. I had to buy a rep as a spare and found it didn't fit, but by a hairline. the 3 mm should be more than enough.

Not true! It doesn't fit exept if your pads are 50% worn...I have both OEM and replica and they need the same spacers...

Posted this in another thread:

With brand new pads HP2 calipers *will not* clear stock 18" USP's. You'll need at least 5mm of clearance, I'm running 8mm spacers and they just barely clear with new pads. Make sure to get a good set of hubcentric spacers, I made that mistake already.

I'm running 8mm spacers, but I believe you can get away with 5 if you wanted. I'm running 8 all around on my USPs to make them sit like an ET35 wheel, and push out into the fenders more, where they belong.
