I was looking at a bumpsteer kit from Pro Motorsports. I did a google search and didn't come up with a website or phone number for the company. Anyone know if there bumpsteer kits will work with a I6 car?

 

They should work on I6 mustangs.

 

A better question is, why do you think you need one? With the stock suspension, you shouldn't much, if any, noticable bump steer. If you do, you need to start looking for worn steering/suspension components (ball joints, control arm bushings, strut rod bushings, tie rod ends, idler arm).

 

Depends the year the 64-66 used a different spindle then the v8 the tie rod ends are a different size.

The reason I ask is that I'm looking at switching to a rack and pinion and I also want to do a shelby drop, which combines to cause bumpsteer. For that reason I wanted to see if they'd work with my car.

 

Well, as Andrew said, some I6 cars use smaller tie rod ends, so the kits may not work. I'd try it without the kit first to see how it drives. I recently did the Shelby drop and swapped to 540lb 1" drop coils and I have no noticable bump steer.

 

Yea I will have to see how the car will feel first I guess. Just thought it might be a good idea while everything is taken apart to do that because I've heard of a lot of complaints about it. Was wondering though, would it be possible to just drill bigger holes in the spindle to accept the bigger v8 tie rod ends? They are the same length or are they not? Don't know a whole lot about steering so I'm trying to figure this all out as to what might work. I guess either that or get a set of used v8 spindles to match the tie rod ends that will be in a rack and pinion kit?

 

No, you can't just drill out the holes. They're a tapered fit, so they need to have an exact taper to match the tie rod ends.

If it proves to be a problem, looking into a 5-lug swap with V8 spindles wouldn't be a horrible idea.
