View Full Version : Axle Bracket Rub?
How close should the axle bracket to the wheels on a 3 link? Mine are very close. 1/4" or less.

That is pretty much normal. A pic and a note about wheel size would be helpful to give a more precise answer though.

As Craig said that's pretty typical. The rim to axle bracket distance is fixed and will not change---unless you have some excessive end play.

Mine were about 1/8" with the American Racing wheels I bought. A simple 1/8" wheel spacer has created the spacing I'm comfortable with.

Fixed meaning that as long as there is a gap the rim and axle bracket can never touch? Even as the suspension moves up and down over bumps?

Right, on a straight axle, which is what a 3 link is, the relationship between the wheel and brackets will not change whether the car is sitting still, moving or going up and down.

Well, the position won't change. But, if you go to the track or autocross, you will be shocked at how much the wheels flex. I had to clearance mine to keep it from rubbing. There is plenty of meat on the bracket if you need to grind some off.
I am running the FFR older supplier Halibrands 17 x 10.5".

Yes, if we're going to split hairs wheels will flex with lateral loading (as we used to say in my engineering days "if something doesn't bend it will break") however unless they're pretty poorly designed &/or constructed you aren't going to be able to introduce enough lateral load with a street or even R-Compound to to flex an alloy wheel 1/4" over less than 7" from it's mounting contact area---unless you slide sideways into a curb!

What,,,, the wheel and the axle are connected and move together? :rolleyes::p

I have a nice groove scraped all the way around the inside of my wheel where the barrel roles over to the rim and had to clearance the bracket. That is running 200TW at autocross. There are a couple threads on the old forum with the same experience.
Here's what mine looks like:

The wheel's offset would play a role in the clearance too.
