I would think lowering the car would make your problem worse. At factory ride height, the tire rods are roughly parallel with the rack. When you lower your ride height, the rack sits lower than the tire rod ends, forcing the tire rods to point up and effectively reaching out a shorter distance. I have my car lowered a bit on coilovers, and I recently added rack spacers to eliminate bump steer. I had to dial out a fair amount of toe after adding the shims to pull the wheels back to neutral toe. 1/2" rack spacers created ~4mm toe out at each wheel on my setup.
I supposed you could try shimming your rack up, but it sounds like you're coming up really short.

Cheers. I didn't measure how long the threaded section of the rod is, but will soon. Using 43mm as the threaded length on the tie rod (from this thread http://mx5cartalk.com/forum/viewtopi...605d0d#p909665 ) it appears you'd have approx. 13.7mm of thread engaged in the tie rod end (43mm total thread, minus 19.3, minus approx. 10mm for lock nut). Are you good with that?
I am 99% sure that these tie rods have never been cut, but I will look into this further shortly. How do you get a tie rod elongated? That would solve the problem.
Ok, thanks Curly. Above link obviously goes into detail on this. If my tie rods end hadn’t literally dropped off the tie rod after setting up for more camber I’d have never thought about it either.

For the time being I’ve reassembled the car with 3.5 deg neg and approx. 20mm thread engaged in the tie rod end (assuming threaded length is 43mm). I have a few things to do in the short term but will get back to this in more detail when time and workshop space allows…or I’ll simply forget testing 4 degrees neg and work on some other stuff
Appreciate the replies.
