I want some reliable spacer, about 5mm wide, and still on stock stud. I s it safe to put that much of a spacer? 5mm

 

Google Nopi, Summit, Jegs, etc. Then search for wheel spacers. I found some in about 30 seconds.

 

I know a place right down the street from me that sells for I think 5 dollars or 15 dollars.

 

Any local autoparts store should be able to get them. I curantly have 1/4 inch spacers. Anything bigger would need longer studs.

 

There is absolutely no guarantee that you can run ANY thickness of spacer, since different wheels have different hub thicknesses. Some wheels even need longer studs WITHOUT spacers (Mustang wheels on an FC for instance). The only way to know for sure if you have enough stud left is to measure. If you can currently get 12 FULL turns of the lugs then it'll be ok.

Keep in mind that if you insist on getting "metric" spacers, that it'll be more costly. Consider getting some cheap Mr. Gasket type spacers in a 7/32" thickness, which is about 5.5mm.

 

Seriously now guys, what is the net effect of 14/32" added to your wheel base? I think the effect it has will be minimal, at best. Anyone care to share some wisdom with me?

 

No the handling effects probably aren't going to be quantifiable or noticable, but maybe it's just for style, or maybe it's to give clearance to the suspension.
