Sweet project!! I'd love to build something like what you're doing. Any concerns about cowl shake with stickier tires and stiff suspension underneath it? Going to put in a rollcage or 6 point rollbar at all?
I'm looking at a 4 point roll bar. I need that for a harness and race seats. I'm also tie the subframe connectors to the inner seat mount and the drive shaft loop.
Subframe I already have subframe connectors installed but I will mod with this in mind.with The US Car inner fender and lower radiator support and a custom front torque box. I think that the car should be tighter. I also welded up the K member and installed the firm feel steering supports.
