As Gayo says. I'm currently running the UM522 shafts from the FS2 (not sp version) & RB5sp/sp2. They have slightly more dogbone plunge into the outdrive so bind up the rear end a little more on power. I personally find that it helps the car as the DB1 has a HUGE amount of rear end grip for a 2wd ... even on the shortest links!!!
If the track becomes slippery or ruts up badly I would change to the UM510 assemblies with the blue spacer on the INSIDE of the rear hub. UM510 is the original RB5 and FS2sp shaft set.
I've not got the lightweight outdrives yet but I believe you can use either length of shaft as they are (again I believe) the same dimensions as the stock outdrives.
Hope that helps.
