I didn't sign up for the codes... but during a month long span when I was turbo swapping, I ordered every week and spent hundreds with them. I guess they took that as a sign and I started receiving them every month since.

88 Montero, StarQuest turbo, Kormex 5speed +tuff-pan w/phoenix f. stage2 clutch, 4in lift+33' tires, 4.875 lsd, short-throw shifter, Aisin hubs, SR big brakes, gen2 uca's, elantra alt, and so much more... 16g turbo w/hardpipes + 4.90 locking disk-brake axle soon (maybe lsd or aussie front??)
