For those who run on Sebring and equivalently rough tracks what is a good starting point for torsion bars and spring rates on a -4 with DOT R type tires and Koni Sports.
I have done a search and see a lot of advice from West Coast drivers. Also spoke to the experts at Elephant (F 23mm R 250#) but again they have limited rough track experience. Thanks in advance! |

Fair enough. Unfortunately I have few answers. I just bought the car last weekend.
added stiffness: A basic cage (SVRA compliant) is welded into a very solid (rustless) chassis. hp: might be a warmed up motor. 130hp according to PO... weight: 1750 or there abouts plus 250 on my account. front sway bar, adjustable welts type rear sway bar, stock but currently disconnected I have raced on Nelsons Ledges and have done several DE at Homestead and Sebring. In my e30 with spece30 suspension I don't have a problem with Sebring as a general course. So in my limited experience I kind of agree with you on Sebring, it is not as bad as it might be made out to be. I am just looking for a starting point to work from. Regards, Miguel |

I am just looking for a starting point to work from. 911 front a-arms? If so, i'd start with the smallest 911 torsion bars (19mm? 21mm? dunno) and use 200+ lbs adjustable springs in the rear. On the big track, running with the rear bar can be beneficial, if the car is set up for it. After that, quick and dirty: Set the ride height, corner balance and use the front sway bar for fine tuning. (IMG:style_emoticons/default/popcorn[1].gif) |
