The GKTech bushings are CNC machined out of solid aluminum billet, not one bit of give here. This, combined with the lower control arm relocation will eliminate all wheel hop and make the car much more stable under hard cornering loads.
Before starting, we removed our stock suspension parts from the subframe and had the rust, undercoating, and grime media blasted off for a good base surface to be welded.
Bare steel rusts really quickly and our blasted subframe had a slight amount of surface rust that had to be completely removed for clean Tig welds. Although many fabricators blast this sort of work out with a Mig welder, Zac only Tig welds and uses a fine electrode and a small filler to reduce the amount of heat going into the work, not to mention that it looks really clean!
