Measure the friction plate thickness. If within wear limit in the manual should be no problem using them again. If you need to replace them then EBC plates are very good. Don't buy Gecko from Wemoto, people have had problems with them.
Took me a while to find the minimum thickness measurements in the Haynes one its 2.3mm, my other manual doesn't give any.
I've measured mine there seems to be some variation between individual plates though none are near the minimum.
All but one are 2.65-2.70mm with an end one measuring 2.96-3.01mm.
Any idea what brand DS supplied ones are?
