Dammmm ..
I hate to hear you broke the engine mounts, Gary. Did the pan hit the bumps in the road or what?
Ride height can be affected by spring preload AND tire diameter. Your low profile tires may be contributing. May want to consider taller tires. The GY Billboards that are meant for original Cobras are 26.7" diameter. ERA says 26.5" is max for their car and they're right .. my Billboards rub the wheel wells in the rear on hard bumps. I prefer to have an occasional rub rather than set the ride any higher
But ask Brian what diameter LSC assumes for their design.
Holler if you need any help!
