WHY DO WE UPGRADE OUR SUSPENSION

i would disagree with the comments on lower control arm bushings.Most i've dealt with last years and yearsThey are hard vulcanized rubber and when installed properly and tightened at ride height offer some torsional resistance to lower A arm travel and can be plenty firm.The poly or or hard plastic is avoided by many the second time around...i've seen that plastic crack and distort after only a couple of years.
I have never had any problem getting enough caster on the front end when rebuilt with new bushings..maybe i've been lucky.
I don't auto cross.
