Is it possible to bump steer a metric car?
I get tube uppers but must run stock lowers. Can I use a different lower to change the geometry? Camaro/Firebird or Impala, for example?
Metric spindles are very short, are any taller stock spindles compatible? The lowers run up to the ball joint and the uppers run down to the ball joint. This seems un-bump-steer-able. BUT, you see a million metric modifieds out there and I'm sure they bump steer them somehow.
My car has 3 inches of toe out in the first 2 inches of droop travel, and coresponding to in in compression travel.

Many thanx

J55,
If you modify the lower control arm with an impala ball joint or with an end from an impala lower you can use the spindle from an impala. 5X5.

I run about the same set up, but I believe I have taller ball joints both top and bottom. New car, so I'm not sure yet. The best and easiest way to improve bump is to install a different center(drag) link. Get one off a 3rd generation camoro. You'll have to do some cutting and welding. You'll have to cut about 1.5" off one side and reweld it together. Let me know if you want to try this, and I'll go into further detail. I just got done making one up myself.

I have done the centerlink deal myself! Works great. You can really see a differance when you jack the car off of the ground. The tow-in changes very little. That's gotta help, especially on a rough track.

does it raise or lower the inner tie rods? I need to lower mine to get the bump steer a little more reasonable.
