This article has been written owing to the increasing amount of people who ring Mini Spares stating that their 1275cc Injection type Mini will not start after fitting a new clutch, especially when they have purchased the parts from another supplier, usually a motor factoring company, rather than a Mini specialist..
There are 2 types of pressure plates, namely  Automotive Products and Valeo.
AP type pressure plates CANNOT be fitted to any original Injection engine flywheels as they will displace the position of the crank sensor trigger and reluctor ring gap when bolted to the centre hub cone (held on by 6 bolts)

VALEO pressure plates are made to fit ALL original Injection engine flywheels but will also fit any earlier Carburetor versions as there is no sensor trigger/reluctor ring gap or ECU fitted.

Injection cars use a reluctor ring in the back of the flywheel to trigger the sensor for the ECU and the Valeo pressure plate has the cone bolt holes in a different position to the AP pressure plate, so look at the chart to check what has come off your car and what is going back on.
Line up any of the 2 holes at the top and check with our chart to see how differently they are positioned.
The two different types look so different with the Valeo flywheel to pressure plate bolting rim perfectly flat whereas the AP is pressed with cut outs and a 9 bolt reinforcement ring.
The centre cone hub is the same on all cars.

Verto Clutch plate fitment is much simpler,
There are 2 diameters:

1. 180mm diameter was fitted to 998cc and 1275cc Metro.
2. 190mm diameter was fitted to 1275cc Mini from 1990 on.

The mating surface for the clutch plate on both the pressure plates are large enough to take the 190mm diameter plate,so if the flywheel is perfect either diameter plate would fit.

Our clutches are as follows:

1. GCK151AF AP product with 180mm plate
2. GCK151MS Valeo product with 180mm plate
3. GCK152MS Valeo product with 190mm plate.

The 190mm Valeo clutch plate has the best friction surface.
AP pressure plates have the highest clamping pressure but CANNOT be fitted to Injection cars unless a flywheel with a specially modified or repositioned reluctor ring is used.

Importation rules regarding vehicles are very specific: Only those over 25 years in age may be brought in to the USA without compilance to Federal Motor Vehicle Safety Standards (FMVSS).
