Has anyone installed a new higher geared diff in their GS? If so, what is required to correct the speedo reading? Please help. Anyone know where I can find front and rear Black factory bumper covers for my 98 GS4?
Thanks

Craig - I have the 3.76 geared RMM differential & the speedo is still correct because it reads off the wheel sensors for the ABS & not the tranny speed. This has been verified by mile markers; another stock GS driving alongside me & lastly but most importantly, by Louisiana State Police radar ( no ticket, just my buddy from the local ride along program ). The only time that U'll throw the speedo off is when U change the overall tire/wheel diameter drastically from stock. Sorry I can't help with the bumper covers but someone had a pair for sale in the Classifieds a few days ago. I think someone had dibs on them but it wouldn't hurt to check again. Happy hunting!
