Additional upgrades:

Internal structure upgrades

Our fabricator designs and builds a custom stiffening kit to each car to minimize body flex and increase road handling.

The kit replaces the factory 18 gauge vertical supports with handmade 16 gauge supports that allow us to install square tubing along the inner sills, rear bulkhead, and crossmember. Also, we make a stronger lower subframe mount which is boxed in and tied to the rest of the added support structures.
