I did a search, but I didn't come up with the information that I was looking for, has anyone put together their own bump steer kit? Hoping to find out where people were able to source the parts from or a parts list that they used to make the kit.

Bump steer kits usually consists of two thick spacers that go under the steering rack and longer bolts.

Please don't use those. It's the worst way possible to go about correcting the steering geometry.

I'll offer a counter point to the concerns about using spacers and a (semi) long bolt to attach a tie rod to the strut. There isn't THAT much force on a tie rod end, compared to other suspension joints. For a tie rod I'd rather have a single shear bolt as a weak link if a wheel takes a significant hit, and have the bolt bend, rather than having a double shear setup and transmit the entire force to the steering rack.

I've had a single shear setup on my racecar for many years and haven't had a problem yet. I do have a large washer on the outboard end of the rod end joint so it won't pop up in case of damage.

Those spacers i was talking about (the ones posted by 914Sixer above) don't go on the tie-rods, they are used to drop the whole steering rack itself.
