Looking to build a 6hp21. Heard some guys used the PD clutches with success, while some other added more clutches for less slippage. With the PD kit not available, what clutches do you guys use?

Not interested in doing a swap as my AWD platform makes this more difficult.

I went with a mash up of pd and Ray bestos to fit as many clutches and steels in a possible. Great results. Every basket I was able to get atleast 1 extra clutch set in. E clutch h I was able to get 2. Be mindful that more friction = more heat so cooling will be a big factor
