Thanks for the replies guys
@ekt: I emailed TD but they didn't respond... Since I will be picking up this project again after a few deadlines from school I thought I'd just order them. After all I can always shorten them if they're way too long
@smokes: The Litemodz shafts look awesome!

I might email them to ask if any of those sets might be compatible for a TRF417... So I could actually try them out!
I also noticed that RDRP has released 'RR' suspension hangers (the ones I use for the front suspension) with different kickup settings. Sweet!

That means the kickup it now adjustable from -3 to 3 degrees - if needed (with a 'kit' setting of 0).
