Hello again guys I know its a little late but if any of you still wanna have a crack at the Rivals Unlimited Weight challenge I’m happy to share my build/tune with you all. This is the only Pontiac G8 GXP in the top 50 last I checked I was sitting 38th and there probably isnt more than 10 in the top 500. Its a fun alternative to the Holden, which no doubt the Holden IS faster but I often find it more satisfying to still be up there (maybe not as high) but with a completely different vehicle.
So lets get to it.
