View Full Version : 4 bar rear springs
06-05-2010, 06:49 AM
Ok this is a general question. I have seen guys run rear springs like 250 lr and 200 rr then on the same chassis another guy will run a 275 rr and a 200lr. But they both run well. What are each trying to do? How does the heavier right rear than left effect the car? Do some makes run better than others with a heavier right rear spring or does the affect happen on most all 4 bar cars?

You really can not look at springs and try to guess anything. Driving style, engine, bar angles, lift arm length and front springs and settings are ALL in play and effect the car. Change one setting and the driver will need something else change to get back where it was. Take a REALLY fast car and put another good driver in it and it may not be close to what he wants and he will be in the way all race, go back to the original driver and he drives away from everyone. Seen it happen. Car won 2 weeks in a row and could have lapped the field if he tried and the next 3 weeks was an also ran.

The first setup would be for tacky,free in,tight in center and off,Second would be for slick,tight in,watch that the 275 dont free you off

More rr usually favors side bite, and more lr usually favors foreward bite, unless its a slinky,hi hike deal.
