'70 Dodge Challenger R/T - big-time understeer!

[tomcat7]

I'd appreciate any help I can get. My '70 Challenger is fixed up with all the extra options (750hp), but I can't get the front end to bite with soft racing tires. Even high-speed tiny directional changes (i.e. Nurburgring) are like skating on ice.

I've tried almost every combination of suspension and ride-height settings, but I just can't click on anything. I need more front-end downforce... How can I get it?

should have race modded it.

How/when should I have done that?

Mad FinnTuners co. has a tune for it. While the understeer hasn't been entirely cured, give it a shot. I have a nasty hunch that the huge lump of metal, also known as "the elephant engine" is the culprit causing the FWD syndrome. Who knows, maybe the evolution of that setup will yield results that are more favorable to neutral or even oversteering behavior.

Thanks, I found how to add RM (didn't realize that was totally separate from tuning work), and now I've got it handling much better - not perfect, but hugely improved.

I just love that car from my youth, so that's the appeal.
