Free Mod for E36 M3 3.2L, E46 323/328 E39 Non-M

[330DTM]

I stumbled upon something very insteresting.

If any of you own the above cars and notice excessive amounts of clutch slip or bad engagement under hard acceleration or quick shifting, this mod may be for you.

This mod removes the check valve in the clutch hydralic circuit.

Here's the link for further details:

Does anyone know if the 97 z3 has these uses? There is mention of the M Roadster being equiped with this.

Best Regards,

I read about this a while ago, if you're not sure if your car has it, just raise it and look at the clutch cylinder line where it enters the cylinder.
