Lots of em out there, I personally use MDS weights, made to work with stock secondary and these weights flat rip. They pull harder than others I have tried and from other friends that have tried more set ups than me. Steve at MDS is top notch in setting these up for you, a full money back warranty if you don't like em, give him a call and BS with him on what your wanting to accomplish, you'll be thankful you did. www.mdsclutching.com
I think it depends on what you are trying to achieve. Im like my gearing/clutching very specific so "kits" really dont work for me. This is a long conversation that could easily go in circles, but for the masses, SLP does pretty good for the pull and go crowd.
Matt, I have heard from a few guys on hear that Carls Clutch job works pretty good, mine are stock so far except for a different spring in the secondary and a couple derlin washers.Here is a link on some clutch talk also,Indy Dan is very good with clutching and he is right south of Minneapolis.
just got the PAR clutch kit to pair with their ultimate combo. mds weights and small helix change. we'll see how it works, any input on your experiences????
