Hey all,
Just noticed a bit of talk on bump steer. And im getting a bit in my 1200
coupe. I just put in the front end usng Skyline struts, 10" vents and 4
spots. The springs are 2" lower and are 200 pound rating. The lower
controls still run down hill a little bit but not much. Its not major bump
steer but its enogh to give me the shits. What would be my best option with
out raising the car?? either change the pivot point for the control arms or
use a spacer??? Any ideas?? cheers...
