Default Corvette 1968 rear suspension problem

Hey im new to the site.
i got issue with rear suspension , on heavy acclearion the rearend plants very hard , it good for traction but the tires rubb the fender on bumps , i got 420lbs composit leaf and Koni shocks , its a street car and more for drag race then autox.
I wonder what you guys suggest to change ?
what you think about Eaton`s ML715 spring?
or the sharkbite sys from speed direct? (you think its good for drag and can hanlde the load?)
thanks!!!!

The firmest Sharkbite coilover is only 400 lb/in spring rate.

For drag racing I'd rip out the whole independent suspension and install a Ford 9" in a 4 link setup.

Most likely the size of your tires or offset of your wheels.
Alternately you may try different rear shocks. I'm running QA1 adjustables on the rear of my car and I can stiffen the rear up enough that it doesn't feel like a suspension any more.
