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 |

Brant,
First I have to say that I don't understand why the effective spring rate would go up with Poly, I believe it would be the shock damping rate that would go up. Second, here's a post I saved from Rennlist that covers 911 torsion bars. Ignore the rear (IMG:style_emoticons/default/biggrin.gif) , and double check the arm distance. Mark S. '70 914-6 |
