I can't see how an off the shelf kit will be the best for all of these individual setups that are out there. Plus I think anything over an 850lb spring is too much, the rest should be done with the proper valving. Ed at progress will build you a setup to reflect your car, for example my car never fell on it's face while shifting once I started flat footing it. The car should transfer a bit (lower spring rate) but the valving should let it stay there and not try to level the car back to a neutral state.

Also, keep in mind the off the shelf stuff was designed around a stock car with the weight distribution of the car greatly different than that of a stock car. Some guys have hundreds of pounds more in the front of the car, and hundreds less in the back half (okay maybe 100 tops as there isn't much there but you get the point) But this all plays a pivotal role in how the chassis behaves.</TD></TR></TABLE>Thanks for info.More $$$$$ :

The obx part was a joke about knock offs, and the rest is well Honda-Tech every time someone goes fast that has a odd part on their car, the odd part get's 100 percent of the credit. Then everyone gets in fury buying the odd or new part.

I haven't seen enough positive reinforcement, so I'm saving the time and running a normal setup. But I think I will have provisions for mounting them in there as a just in case sort of deal.</TD></TR></TABLE>

thanks ryan. cant wait to see your hot rod GL with the build.

on a rwd a torsion bar uses the weight distribution of launching and rotation of the rear end to slam the rear tires in the ground. a less severe setup, or less violent setup is a set of ladder bars. with a light car not making much power a very very short set of torsion bars is the way to go. i know this means nothing to this forum due to we are all mostly fwd's, but we have played and played with torsion and ladder bar setups on our superstock, along with shock adjustments.

there was a guy on here that incorporated a ladder bar system into his fwd civic.

My 1970 Duster had torsion bars on the front suspension. When I'd launch the car the whole car raised up 2-3" to plant the rear tires.

The bars ran from the lower control arms back to a someplace under the floor pan under my feet.

Has anybody thought about this type lay out?

Sorry to hi jack the thread.

didnt practically all dodge/mopar cars have front torsion bars in the 60's and 70's. some guys pick those chassis to run in stock/superstock just for this reason. many have their arguements about this being beneficial. yes they run back and connect to the frame i believe

its always fun building pair of equal length stainless steel headers on a mopar with front torsion bars...especially if they want tri-y's

Yes, I believe all did.

Yes the headers on the drivers side came in 3 pieces from some companies.

I do believe your right. If I'm not mistaken they used them from late 60's to mid 70's on most of there cars. I know my dads 70 T/A has them.

most of which parts and suspension have mixed results. only the few will know how things work together in unison. having all the trick suspension parts dont do **** if not used and setup properly. torsion bars are not anything new. actually there pretty ancient.

lets see if the pat pending jj suspension stuff comes out. love to see what that can do for 330s

what if an NA car is lifting the front-end right off the start and putting much flex on the wheelie bar ... what would you rota92 suggest to keep??

...26x8.5 fronts

to the OP, sorry to jac' just heard that rota92 was the man to talk too
