I'm not exactly sure where to start with this one..
Let me tell ya where I'm coming from... On the rear suspension... I've been told to increase spring rate when I step up to a non-poly spherical type bearing. I was told that without the drag of the poly bushings, I would need to go up 100ish lbs to compensate for that drag.... and keep close to the same effect suspension rate back there. So... Here is the actual question. If the above is true, would it not then be true that with a front bearing suspension (like Mike Muellers).. that the front spring rates (be it torsion or coil over) would also need to go up.... In order to keep the front rear balance... Brad..... On the track only cars you set up with 300... 400... rear springs... what kind of front spring rate do you end up with... somewhere I once saw a conversion chart to compare torsion bar milimeters to coil spring foot pounds. brant |

Yes on a 6cyl car. No on a 4cyl car.
The sixes tend to be very close front to rear spring rate wise when they are "dialed". My fast 914 4 cyl drivers tend to have a stiffer front than rear. This allows us to dial in the rear with the front bar and adjustable shocks. Start low. 90% of the questions you are asking have to do with driver comfort. Some older guys can drive the wheels off a highly sprung race car.. others like them a little softer. B |
