I know.. I Know... but are they that bad? I just want to push my back wheels out a little. I can't afford offset rims right now.
I was thinking 12mm.. but I can't seem to find them in that size.. and guaranteed for the 2005+ Mustang.

Here we go...

 

I know.. Sorry.

 

Don't do spacers. I made that mistake in the past and regreted it. Just do your research and get a wheel that fits your car properly.

 

http://www.stangsuspension.com/store...idproduct=1417 that's 12.7mm but as they said, you'll need longer wheel studs

 

Find wheels that fit properly, it'll look 10x better also.

 

Thanks for the comments. I guess I can wait get 17x9's or 17x10s for the back....

 

I'm not a big spacers fan, but if you search around you'll find threads where users praise them like some folks prais Loudmouth mufflers. There are some on eBay that are reputed to be made on the same production line as H&R spacers, at half the cost. If I had a couple or four hundred dollars to play with I might try them for autocross: a wider track couldn't hurt!

H&R is a serious manufacturer, and make quality goods:

I've had 1/4" spacers on my front wheels for over 18mo and 20K miles with no problems of any kind - no vibration, no steering wheel shimmy, and amazingly enough the wheels haven't fallen off[8D]

 

Go to www.mustangwheelspacers.com I have the 5/8" kit and love them & they fit like a glove. Kit comes with longer studs -- no worries. JAK
