Rear lifting in hard coenering, Too much spring? Options

[retrotech]

I wasn't ready to deal with the suspension yet, but today I was told my the guy behind me. In hard cornering, instead of being flat, thew rear corner would lift. Thats not good. This was the first fairly hard drive, with some R Gruppe cars.
The PO said they were 400#, I assumed he was mistaken, that didin't seem reasonable. He said he has had a track 914, and that is the set up he was successful with. So what do I need to do. It has front sway bar, don't know what the torsion bar is.
What are the suggestions. I don't care about comfort, I just want an optimal performance for street & track.

1970 w/2.8 2000#


Thanks

Sounds like the front is too soft if the rear is lifting. Of course front wheel drive cars do it all the time and I have seen some 356's do it also. Not good for a rear wheel drive mid engine car, unless you are braking really hard. I imagine you are not braking though so that if in fact the rear springs are 400# they are probably too stiff and need to be softened up about 100# to 150# or so. I run 300# in my race car but it is using Goodyear slicks and 23mm front T-bars and really big front anti sway bar. Of course you can always go stiffer on the front but that would be for a race shop to evaluate and see what you actually have. The rear springs can be measured and the front T-bars are color coded as to size or stamped.
