I have some 3 pc 18 in racing hart m5 wheels and they wont clear my front brakes. I bought these rims when I used to have an eclipse for 3000 so i would like to keep them. Where can I get spacers and will that effect my performance in any way? I would have to put them both in front and back to make them equal right?

 

Spacers may help caliper clearance but it may kick your wheels to far out where you'll run into rubbing issues. What width and offset are the wheels? How much do you think you need to space it to clear the caliper?

To answer your question tho, H&R builds the best spacer imo. Checkout HRSPRINGS.COM for your application and see who their local dealer is in your area.

As for the performance aspects, spacers will affect how your car handles. For example if all your wheels and tires are the same width and offset and you only space the fronts, this will cause the car the understeer more. If you only space the rears, your car will oversteer more. If you space both front and rear the same the car will pretty much act the same (oversteer/understeer) as if you didn't space it at all except it will be a little more stable due to the fact you widen the track.

Hope this helps and makes sence...
