Default Wheel Spacers

Has anyone used wheel spacers to provide outboard clearance for bigger brake calipers?

Normally, when you use spaces you change the geometry. That can screw up the handling. To make it handle like it does with the factory wheels, you need to look at centerlines, offset, etc and make it come out the same as the factory wheels. It would be better to use some wheels with the correct offsets that are made to clear the new calipers if available

Spacers won't, on their own, ruin your suspension's geometry. They're built to make a wheel have a more negative offset. With two wheels that have the same width, a more negative offset will cause that one wheel to sit farther out from the original position. If you're using them to 'correct' a wheel's offset, they can actually be beneficial.

http://www.tirerack.com/wheels/tech/...jsp?techid=101 <= Pretty good info on offset.

I've seen cars run on spacers for years and not have problems; however, it's kind of an extreme measure. Unless their is a wheel that you MUST have that doesn't have the right offset, I'd go with a wheel that's closer to the factory offset. If you do go with a spacer, spend a little more and go hub-centric. This basically centers the spacer on the center of the wheels using a little lip as opposed to other spacers that 'hang' off the lugs before the wheels are bolted down. Check and see what it takes to install a hub-centric before you buy; I've heard they can be moderately difficult to install but I don't have personal experience doing it. Oh, and here's a good link for figuring out what types of clearances you'll be dealing with. (http://www.1010tires.com/WheelOffsetCalculator.asp) You can type in something like 'X mm to inches' into google and it will convert for you.

Spacers will not change your SUSPENSION's geometry ......but if you are going to run spacers.....they should be no larger than 1/4 inch if they are not hubcentric......and no larger than 35mm with studs built in....that's when you start running into fender issues lol ....

As Kona stated, don't run spacers larger than 1/4". After that point I would go with wheel adapters. Spacers put added stress on the wheel studs. Wheel adapters do not.
