just lowerd my GP with coilovers ,just wondering whats the best wheel spacer set up for the GP, i heard its 15mm, anyone try 20mm, anyone have pics, just want to know my options before i buy, thanks....

 

Even with the JCW springs I had rubbing in the rear with 15mm spacers using OEM GP wheels and 215/40x18 tires. The tire rubbed on the wheel arch and on the wheel well liner. I think 20 would be too much for the rear. Depending on how much you lower with the coil-overs you might even have rubbing issues in the rear with 15mm spacers.

There is a lot of room in the front for spacers. I have no problem with 15mm spacers and don't think 20 mm would be a problem.

I went with 15mm front and back because they are about the max for the rear and work well with the length of the wheel studs that I use (instead of longer lug bolts).

 

Thanks quikmini, that's the info I wanted to know, looks like I'm goin with 15mm all around just to be safe, I don't want the fronts to pop out more than the rears, thanks again for the info
