    All depends on your buget. Is your car modified?
    My clutch has been slipping really badly i can't go over half throttle.

    I've been doing lots of research on clutchs

    for the sachs clutch its around £550 from Thorneys or Regal the you will need a release bearing for around £90-£100. then labour of about 4-5 hours

    The clutch i'm going for is the Helix organic clutch its £370 delivered from Rallynuts.
    Mike warner and a few other people had had it for some time and has handled fine on their cars of around 300bhp and 333lb/ft torque.

    the Astra/Zaf has the same part numbers for the clutch and coverplate as the calibra turbo.
    But the release bearing is different.

    There are a few people running near 300Bhp on the standard clutch for some time, with no problems as such.
    Mind, the kit suggested by dazerc sounds reasonable.

    Yeah there are people running high power on standard clutch but there are also people running standard power and the standard clutch is slipping.
    I you are spending £200 on labour its worth a couple hundred to fit a uprated clutch so then you know its going to be able to handle the power.

    well i wont have any labour charges as i'll do it myself and i can get a slave cylinder fo £60(oe spec)
    i actually changed my slave cyl 4 months ago as it was leaking, but didnt do the clutch as it wasn't slipping then and i am saving for flywheel and clutch.
    my car is standardish power at the mo but an intercooler ans phase 2 remap of some sort will be getting done at a later stage.
    like the sound of the kit dazerc listed but courtenay do a clutch for £195.
    i like to save where ever i can

    The courtenay ones price does look good for £195 but noone seams to know what make it is? or what power it can handle? they just say that its uprated

    Seems to be good for their stage 4 Ideal for your fast road car, our uprated clutch will withstand increases in power and torque without the slipping that may occur with a standard unit yet still retain the drivability of a standard clutch. Essential for all cars running our Stage 4 Software.

    The courtenay one is a LUK cluch for a calibra turbo


    I went for a helix for mine, £370 + the slave cylinder..... Thats a calibra turbo item too but with an uprated pressure plate.
