My car started launching erratic a couple months ago and I've been through basicly the entire suspension and have not found the cure. The last piece is rear shocks. It has strange doubles (the silver ones) that were one the car when I bought it so don't know how old they are. On strange website they are listed as street/strip shocks so I'm wondering if I need better shocks or just rebuilt and re valved? I've been debating everything from afco BG's to ohlins. Just don't know if the ohlins/Penske has an advantage over afco's on a car like mine. 2470lbs best 60 so far 1.13. 33x15 slicks tube chassis 4 link. What are most using on a car like mine?
