Rear Suspension upgrade

[bubba622]

Last year i became the new owner of a 1990 build of a B&B cobra, all is good, considering its age, one thing i need advice on is upgrading the rear suspension. Forgive me for poor terminology.....it has coil springs in the rear, with shock absorbers, they do not run up the center of the spring, there is a bottoming out occurrence quite often,especially with a passenger aboard. .When i had the car inspected i also at the time had 2 rubber discs placed in the top spring cups to add a little height, it did but not enough. Would it be possible to replace the stock shocks with something beefier, perhaps something with a coil wrapped spring to stop the movement or do i need to replace the springs themselves with something stiffer, or is it possible to place some rubber blocking around the spring to help out. There is a photo in my gallery of the rear suspension setup and it is merely a street cruiser, no racing ......any advice would be appreciated...regards
