Like Special Agent said, were getting the shocks locally. They're 125mm and I flip the rear lower link/shock mount at the axle to lower the rear end a hair.
You could probably use 120mm shocks and not flip the rear lower link/shock mount. I've had people ask about the Yeah Racing shocks, but I haven't had a chance to see/use/try them.

That's part of the reason I like to see build threads from the users if these IFS rigs - so we can see if my initial suspension setup works as good as I thought it would and what changes people are making.
All of the feedback I've gotten has been positive. I've asked the local guys what they would change, what would make the rig better, and haven't had anything suggested for improvement.
Young_version changed his rear springs (said his shocks were never as smooth as mine) but that's the only change I know of to his suspension.
If you run a motor with less power and torque than a Pro4, I suggest a lighter weight oil in the rear.
Also, DTP has been running a standard straight sway bar in the rear of his IFS. The straight sway bars don't serve as bump stops to limit down-travel of the rear axle like the sway bars I make. DTP has pulled ball ends off his rear shocks two or three times.
As I said in the first post, I
highly suggest one of my rear sway bars. It keeps torque twist under control with the big motors, keeps the rear under control during hard cornering, limits rear down-travel, and makes the front work in the rocks.
