ZX-5 Advice and help needed please

[delorean_dude]

Hi

I have a lazer ZX-5 Sp with alot of upgrades. Brought that way. Been running great for a while now. Several things Id like to fix or clarify. Are the front or rear suspension arms the ones with 3 settings on. all the manuals show as the front but mine are the other way around. 3 spring attachment points at the rear.

The second thing... my car after running a while down the park testing setup etc started to make a grinding sound under heavy acceleration. sound like it a gear slipping or something. Its comming from the back I think so stripped it down and looked at the diff and it doesnt look like the diff gears are warped or melted (seen that before on a car i had some years ago).

Any idea what it could be.

Thanks in advance
