No, 5mm max and even that is pushing it. You lose 2 full turns of a lug nut with only a 3mm spacer (wheel stud thread pitch is 1.5mm) which is the widest I would run on stock studs.

 

Okay. Well, do H&R (or Kics or Ichiba) 15mm rear spacers with the studs require you to cut down the factory studs? I don't understand how you can run a spacer narrow than the width of the factory stud.

 

It entirely depends on the wheel you are running. Most aftermarket wheels have a recess there that will allow clearance for the stock studs. I believe AP2 wheels have at least a little clearance, should work with 20mm spacers and possibly 15mm.

 

I'm paranoid. I'm running the race version of the CCW Classics and they have holes cut for this exact reason, all the way through the wheel. Helps to take a closer look at when you run. Sweet. lol

 

Does H&R make a 20mm spacer with built in studs? I have not been able to find anything.

 

Yes, #4065700 and #4065640. Make sure they are DRM style, that is the bolt on kind.

Sweet thank you. I think I will end up giving the 20mm on all four a try. I am already at -1.5 camber front, and -2.0 rear.

 

ya man, i would like to see pics if you could post?
