Started with 4 door full weight GC8 sedan.
Then add the following:
Full 6 point CDS tubing roll cage
Tailshaft loop
Gearbox/flywheel shield
Parachute pack and mounting
Front mount intercooler and piping
Larger turbo
External wastegate and piping
Larger stainless 3 1/2" exhaust system
Test Dummy / Driver (82kg - Pound??? not sure )
As well as other mods.....
It all adds up.
