So are there any sources out there that still do this service? Mazdatrix no longer does it and I can’t seem to find anyplace that still does it. I want to shorten my final drive but thinking the 4.3 off the gtus may not be short enough to make a big enough difference for me. i may still go for it but the more i think about the 4.88 or evem something in between I think that makes more sense. Does anyone have any leads on a reputable person to do the work and what ring and pinion’s are still available to do the work? Mazdatrix still has a 4.88 available but thats all i know.

 

the popular (cheap) one is the Kia 4.77 set, its under $300 new

i can't be the only one, but every time i ask a welder to weld something they don't want to do it...
