What is the thickest wheel spacer that can be safely run on the rears? I'm looking at buying some wheels and the rear offsets are a bit too high... 18X9.5 +55. I don't really want to replace the studs with longer ones as I would simply look elsewhere for betting fitting wheels if that's the case. Thanks in advance.

 

For Slip-on:
Really it depends on the wheel center, but 5mm is about max I would do on stock studs, maybe 8mm. 10mm seemed like too much and not enough thread engagement for me.

bolt on:
as much as you can fit.

 

Thanks. So by bolt-on, I'm assuming you mean spacers like Project Kics? It looks like I'll go that route. Would you recommend 10mm or 15mm for my setup?

 

Talk to Rishie: http://www.autornd.com/catalog/

He can advise the proper parts for your desired look.

 

Ive got Project Kics on my FD's rears, I put on some thread lock blue just for some safety and torque it to spec. No problems for me so far, I know a few other road racers that do the same setup with no problems.

 

Thanks, guys It looks like I'll go with Project Kics spacers if I end up getting the wheels that I'm looking at.

 

Depends, what tire size are you going with? and have you rolled or pulled your fenders?

 

I mentioned this in another thread: You can get extended shank lug nuts that have an extension past the acorn into the wheel's lug hole, and thus provide an additional 1/4" to 3/8" of thread contact.

I'd HIGHLY recommend that over thread lock compound.

 

Peter, do you know where I can get such lugnuts? Thanks.

burtoncr, I'm probably going to go with 275/35/18 in the back. My fenders are not rolled.

 

Whew! took me a while to find it:

Massey's Accessory Shop
Oklahoma City, Oklahoma

Thanks a lot, Peter. I'll contact them if I decide to go with those lugs.
