Yep I had the Southbend SMF and uprated clutch pack, it was very noisy, it came out in the end. on a petrol engine fine but a diesel I wouldn't recommend at all. Some people may not be put off with the noise but I am very particular about my cars and it has to be 100% or it gets replaced.
If you go for the SMF and uprated clutch then dont go for any uprated mounts or bushes, I had the pendulum mount bush in and I couldn't get reverse or 1st gear?? sounds weird that a clutch can do this sort of stuff but there you go.
Speak to Scott or Ryan at Darkside Development im sure theyll sort you out with the right advice and a good price
