ECE 2.5 drop spindle - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I am going to run ECE 2.5 drop spindles up front on my 72 2 wheel drive. Anybody see any problem with running 15x10 wheels up front. 3.5 inch back spacing. Any pictures.

I have no experience with what you are asking, but people are running into issues with rubbing the lower control arm with a 15x8 wheel and that drop spindle, I would think that a 10" wheel would make it worse. I'm also not sure on the backspacing, typically I take the wheel add an inch for the bead and divide by 2.

With only 3.5 backspacing you shouldn't have any issues. If you couple it with a drop spring though, the lowness is going to close up the fender gap enough that you're gonna risk rubbing the outer fender lip. Just a spindle though, and reasonably short tires, you should be fine.

I am only planning on running a drop spindle. I called ece and they said the 3.5 backspace is the max. But wanted to see what everybody has ran into. Anybody have any pics of the gap on the lower control arm?

Worst case, you trim the lower arm a tad. It only takes a minute or two with an angle grinder. Absolutely nothing to be concerned about.

How much should be taken off? I have my control arms down bare right now to be sandblasted.
