Doe anyone have experience with BMR subframe connectors on a 67 convertible? I am trying to eliminate some of the Cowl Shake associated with these (convertible) cars and am wondering if these will help reduce Cowl Shake. I have done most of the usual things on the car like Shocks, Front and rear Heavy Duty sway Bars, Rubber front suspension bushings, and recently updated the rubber body mounts to Urethane body mounts by Energy Suspensions. My car is a cruiser with a 326 and a turbo 350 AT. It does not see drag racing, or Track days, but does see some spirited driving. I am just so annoyed by the shakes and probably spoiled after driving my modern era BMW.
