I have 18x8.5 front and 18x9.5 rear wheels what size spacer do you recommend for a flush look. Thanks in advance for the help!

 

you need to give the offets or your wheels, and tire sizes.

 

Sorry Offset : 32mm(front) & 35mm(rear), 245x40x18

 

I'd say 25mm on all four.

 

those would work.

 

Don't forget about new studs...

Or you can get the Project Kicks which bolt on to your existing studs.

 

I've never seen those. Gotta link?

they come with studs attached to the spacer, and bolts to attach to your stock studs. the studs that come with the spacer replace your stock ones.

 

That is a pretty sweet design....

 

FYI, all brands of spacers over 25mm use that design, H&R, Kics, Eibach, Ichiba etc.

 

That's what I've got. They work great. Just put some loc-tite on your original studs when putting them on.

 

Very good quality. I have 20mm on my rear wheels.

 

+1 Yeah I forgot to mention that anything under 25mm (for most of the spacers) isn't safe enough to just bolt on. That's when they supply you with longer studs.

 

I actually didn't even use loc-tite. After about 50 miles I took off the rears and re-torqued the spacer bolts. To my surprise none of them needed to be re-torqued. I've driven over 5000 miles since and no wobble or shake at all.
