Ive just had my otherwise standard fabia vrs remapped at Big Fish Tuning and ive noticed the clutch is starting to slip. Ive been looking at a Sachs clutch but i was wondering if the standard sachs clutch will be strong enough or ill need to buy the competition one ?? The car has been mapped to around 170 bhp im not sure about the tourque.

Any help would be appriciated

Don't boot it below 2K revs.... If its slipping after then, then I would be buying a new clutch.

What's the mileage/age of the car?

2005 and its on 65k
