I did & I don't like it! I've heard that they are great & I'm not saying their not, I just didn't like mine!
Its a Fioroni Turbo sliding clutch & I installed it on my Storm Pro with a Medial Pro M2K 8 port eng. I didn't know about the special clutch bell thats supposed to be deeper & about 1/2 mm bigger, I found this out after I installed it so I only ran it for about 20 laps total & never bought the bell.
I'm going back to my 3 shoe that I really liked. So if you deside you want one (its the small flywheel for Kyosho & GS, the carbon shoe set, nut & washer) I'll sell it for $45.00 shipped (in the US) thats alot less than the new price!
I have the regular sliding clutch on my Lightning. I will never use a regular clutch again. I was chewing up AL clutches all the time. I put on the sliding and have yet to wear out a set of shoes!!
