macarbon_john A few weeks ago I sold a customer a set of refurbed R129 wheels. Due to the car being a '75 (I think) and having tapered front hubs, he had to go with the 25mm spacers. He was very happy with how they turned out. He reports no rubbing issues though he thinks the rear clearance is pretty tight. He did go with 215/55 tires to have a little thicker sidewall. So that probably helped.

The car previously had some hideous wire wheels on it. Unfortunately, I don't have a good before picture.

Good point, thx

Looking through this forum ideal offset for this size rim would be 11mm. I found posts about using 20mm spacers but none using 25mm spacers
I like the 25mm spacers because they bolt to the hub and the wheel would bolt to the spacer eliminating the need for long bolts.
Any concerns using 25mm spacers?

roncallo Well according to this post it looks like I ended up with 4 20mm spacers. Wont really know until I take them off.

Just confirmed they are 20mm. Found my E-bay purchase record.

Betcha the OP is truly confused now.
Your actually correct I started out with 15's went to 20's or 25's in the end when I noticed the rubbing on the shock towers. They are on my car now they look like 25's looking through the spokes.

Sorry for the confusion and thanks for pointing that out.

dugald Well spacers are a pita and actually illegal in some places. JR's experience suggests you may need them for inside clearance but mine suggests you may not.
A trial fit is in order.

roncallo The wheels in this thread are the same size and ET as yours.

roncallo 15 mm spacers are optimal for those with rolled fenders and 225 50 series tires. 11mm will work if you don't put wheel weights on the inner rim. 25mm spacers and your screwed.
