[Fot] Gt6/spit diff question

[Scott Janzen]

you might want to check driveshaft angles before you offset bushings to change the height and angle of the diff.  
If this increases the differential between the driveshaft/u-joint angles front to rear, it will result in more vibration at high speeds, which I've found to be an issue with at my car at speeds above 100-110. Ideally the diff and trans are at the same angle to the driveshaft, and/or their axes are parallel.  They're not the same in my car, but I've tried to manipulate mountings to get them as close as possible with a resulting decrease in vibration.

Are the rubber bushings at the back end of the diff where it mounts to the
frame upright replaced for racing? If so by what? Rubber? Aluminum?

Thanks
