Can't see spending $600 on shocks that don't last any longer or perform any better on a 50 year old street car
The reason I mentioned my sprint car is I tried Bilsteins on it. They were the worst investment.
Other racers always had one set of shocks at the bilstein truck in the pits getting fixed while running another set on the car . If you have money to waist get Bilsteins . If your racing the car Get extras . I was on a budget and I did not have luck with them compared to QA1.
Race cars? QA1 adjustable,
For a street truck or car get a shock you can replace at an affordable price for maintenance intervals.
