1967 Valiant Suspension Dilema

Although I'm heavily in favor of just beefing the stock system, it all depends on the class you will run in.

The Sandberg's are the only ones that have won a top trophy spot in C Prepared at Nationals with a mopar. Both front and rear suspension were changed - not because it couldn't be done - but because it saved time and money working within the expertise they could bring on board. It still took some testing and development. Nothing is a bolt in winning combination in classes that allow alot of modifications. And if it was good this year, next year you can be sure the ante will be upped by other top competitors.

The other mods mentioned will take it out of the Street Prepared based classes. So whatever you do, whether SCCA or another group, need to know the rules for the class.
You might look into CAM-T if you're looking at SCCA autocross classes. A couple mopars on the west coast have been running in it, and there's prob others I'm not thinking of. Hotckhiss should have entered in it. They kept hinting at it. I think they needed to make some changes to fit into the rules, but I don't think thats the real reason they didn't enter. They should have done well - the car seemed well set up and they had good drivers. Who knows.
