Which post forward did you do? C3 or doo Frankenstein?
C3, At the time I did it I think it was the only viable kit out there.
MASSIVE differences but don't forget the added geometry change by swapping out to the '14 spindles and skis if you can find them.
Those few degrees of angle change make a big difference too.
To be honest, I wasn't that fond of my XP after giving up my '05 REV.
The REV was just super easy to sidehill, carve, whatever I wanted with very little input from me.
The dang XP was really pizzing me off and I thought I made a huge mistake by buying it.
That's all in the past now since the mods I did, I'd never go back now.
It's even more fun than the old REV now.
Just need snow!
After the post forward I also got a gauge re-locator/vent kit
Also added a 3rd rear wheel in case I lose a bearing, I can get out on the other two.
With only one you're screwed.
