    Doe's anyone else had a bad clunck from the rear when they change gears hard in a manual? Mine sounds like the diff housing is hitting the floor pan?

    Hey there ive had the same problem recently, and the best way to check if its ya diff, jack up the back end of ya car, and leave the hand brake on. start ya car, and go from Park to Drive. Does the tail shaft move more then 1/6th of the way, if so you got major diff problems. Thats what ive learnt, i had the diff clunking for a few months, but had to buy a new one. LSD is the way to go

    Yep lsd and a good one at that no prob's with diff itself, thinking it must be something else as i know of another vx r8 manual that does the same, only happens with trac/off and changin real hard.

    it might even be your exhaust or mufflers hitting the floor .... maybe check the engine mounts to see if the engine isnt twisting under load ( hard excelleration ) ...
