i have been on euro car parts looking for a clutch kit, 3 come up for my car.

1- 3 piece LUK clutch kit (clutch plate, pressure plate, slave cylinder) £151

2- 3 piece LUK clutch kit (clutch plate, pressure plate, slave cylinder) £213

3- 2 piece LUK clutch kit (clutch plate, pressure plate, slave) £101

right the last one i can see why its cheap, but what would the differerance be between both 3 piece kits? this was searched using number plate. added bonus is they are offering 15% discount on clutch kits.
