Also I need to order a downpipe gasket from bmw does anyone know the right part number for the downpipe with 129mm x 57mm from center of the studs.

The clutches one will be for a car with aircon and one will be for one with out im guessing

You dont want an aircon clutch they are crap

Can someone explain why there are different clutches for air con and non aircon?

why would an aircon clutch be different? surely the air con has no bearing on the amount of peak amount of torque the clutch has to transmit.
obviously when its on it will rob a little bit of power but when its off the engine is just the same?

one of those claims 228mm pressure plate with 228 230 or 235mm friction plates? while the other claims 230.

when i last got mine they asked whether it was 228,230 or 235mm, and tbh i had no idea there was any difference, iv had 3 different clutches in and out, one was even a 320 one temporarily and i see no difference?
in fact next time i do a 320 one it will get a 325 unit, as there a direct fit, the pedal feels the same, its a supposedly stronger clutch and its about £30 cheaper. i see no bloody difference in them.

Ask Dan about the differences in air con and non air con clutches you will be suprised.

Aircon or 2.7 spec Sachs clutch has a cush-drive centre plate, I dont know why they still sell these as from what ive heard they have always been sh1t. I welded mine shut in the end as it couldnt cope with the M52
