Chassis supports and door bars – project ready

Chassis supports are now ready and welded in. Door bars still need to be painted. Templates were accurate enough to make the final fitment easy. The biggest effort was cutting the 3 mm steel plate with angle grinder. Top looks wasn’t the priority this time.

I was lucky to get help from a fellow race car builder who suggested a couple of smart changes: to add triangle plates, use sturdier tube for door bars and make them removable. It’s a street car after all. Door bars are made of 38x3 mm steel tube and bolted on to the support in the front and to the roll bar in the rear.

The idea was to weld the door bar front mounts as high as possible, and still keep the car entry easy.

And here are the results: before and after comparison. Bending reduced roughly to the half. On the road chassis feels more solid and car responds to steering inputs crispier than before. In general it felt like new set of stiffer shocks was installed. Shakiness and 60 mph shim are also gone. Am I satisfied? Yes I am. It wasn’t realistic to expect bending go down to zero. Current situation is a clear improvement and stiffer bushes are next on the list.
