Definitive diff mount answers?

[shakespeare]

Drive line binding in these cars is exacerbated by variation in tyre height. It may sound obvious but the first thing I would check is tyre pressure, then use a tape measure and a flat level surface to confirm all four tyres have 4mm or less variation from ground to the top of the wheel rim.

This actually occurred on mine after I had the Turbine Tech forward diff and CPE rear diff mount installed, I found that after kmh001's suggestion to vary the pressures I found a front to rear variance of 4psi reduced alot of my vibrations (greater weight over the front so had fronts at 40psi rears at 36), though the RHS engine mount on mine was also wearing out and I think that having a stiff diff made the other week points in the driveline more noticable!

Interestingly, I just went down to my mates workshop and re-did the nitrogen in my tyres, 38 at the front and 36 at the back), and it's certainly quietened it down. Thanks for the advice dude!!!
