Your garage will advise you on if you need a replacement DMF when seeing it(Which by your planned use will be upto the job & reliable)
I did need a new DMF as the 'give' / play in it was too much too risk leaving it in.
I have read & heard however some tuners say theyve never seen one that needs doing.
I have been very happy with my Sachs upgraded clutch kit & OEM provided and fitted by VWR 40k miles ago...
A slightly stiffer pedal feel but feels more purposeful, I hate light fluffy over assisted pedal feel on brand new cars
SteveP recently had the same decision to make on DMf /SMF & clutch kit, he opted for Helix & SMF
I think, do a quick search for his thread or drop him a PM
