I have a stock '76 2.0L car and have been pretty successful in AutoX at the local PCA and SCCA level. For PCA, I run in the PA class.
I currently have red Koni's (age unknown) with 90 pound springs on the car. I also have front and rear factory sway bars. The shock/spring combo seem to work well enough for street and reasonably aggressive driving My problem is that my rear end seems to come up and dance all over the place when I'm AutoX'ing and I'm trying to get it more planted for the upcoming season. I've had folks recommend I upgrade my rear springs to everything from 140 up to 180 lbs. Any thoughts on what springs I should go with? I'm not looking to replace the shocks and springs or do any other suspension changes right now as I can drive the car very well in AutoX, but want to try and pickup some handling and hopefully a little time. Below is a pic of my car from behind to give you an idea of what I'm trying to correct. Thoughts?  I appreciate any and all comments! :-) |

Hey JP, what flairs are those? What tires were you running under there? I may eventually have to flair the rears and yours look good. How big did they let you go?

How big did they let you go? The tires were Victorracers 205s & 225s X15. The flares were free.......just a hammer & dolly to the original fenders....bout 10000 whacks apiece. That's hard on the hands but mine still worked back then. (IMG:style_emoticons/default/biggrin.gif) I tried to stretch the rears more to cover 10 inch slicks but that was a bridge too far......but I got close, maybe 3/4 inch short of width. The front flares ( I originally moved the fender opening up bout 3/4 inch) did cover the 10 inch slicks with a 5.5 inch backspace wheel. The pic shows full compression of the front suspension......also did lock to lock. A few minor adjustments were needed. Attached image(s)

Pounding metal is one of the many things I don't do....well or otherwise. |
