Hi Guys,
Today I bother you on behalf of a friend who recently bought herself a beauty of a GX Coupe. This would be her second GX and this one's being built purely for drag racing. The car's drivetrain is entirely original from the engine down to the tires. Unfortunately the former owner did a lot of highway driving and the diff moans quite a bit at 130km/h. Now her A12GX engine and gearbox are being rebuilt for drags as I type this, but she's worried her diff won't hold up with her heavy foot. However, yesterday she spoke with a gentleman who said GX's were produce with 2 types of diffs:
1 -imported - diff center removes to the prop'shaft's side
2 - local - diff center removes through a rear backing plate

He also said she'd be better off rebuilding the original diff if it is an import, rather than buying another. We have mentioned to the man that the car would be driven abusively as its a drag car.

Any advice would be highly appreciated
