I have a 04 Coupe and want to do the 4.083 final drive up grade will this work with my stock pumpkin and will the kit that you buy have all the stuff included for install and does anyone know the best place to buy the gears at the best i have found is like 470.00 shipped is this good or is there better to be had. thanks

 

you should consider upgrading to an aftermarket LSD at the same time

the $470 is probably just for the RING and PINION and doesn't include the spacers or anything

 

Yeah i think it is just for the RING and PINION where do you find these spacers and stuff why dont they sell the whole kit together where do they expect people to find all the stuff to make this work?? Does any one know of a place that sell the entire kit for install???

 

plenty of places, search z1 auto, they have good stuff
