General Information:
The 22 shocks fit with almost zero modification
The 22 shocks are the same length as b4 shocks (at least to the eye)

Mounting the front shocks:
upper mount:

I removed the blue aluminum AE shock bushing, since they are smaller in diameter than the 22s. The issue now, is the shock screw is A) not secure to the shock tower, and b) a little short. So I replaced the stock length screw with one that is just a tad longer. I think 7/8ths, but don't quote me. To secure the screw to the shock tower, I used a tiny 4/40 lock nut. The ones I have I think are losi, small, and gold in color. (Something like this: http://www.amainhobbies.com/product_...inum-Locknut-5 ). Not only does the lock nut lock the screw to the tower, but it provides the EXACT right spacing to keep the shock from rubbing the shock tower. Simply use the factory 22 shock bushing, and a larger sized locking nut for the very back, so the shock doesn't pop off the bushing.

lower mount:
The lower mount onto the arm works just fine, but there is a little play as the 22 shock eyelets are skinnier. I simply used a 1mm shim from this package here: http://www.amainhobbies.com/product_...lstud-Washer-8

Mounting the front shocks:
upper mount:
The rears were just a tad trickier, but still painfully simple. The top shock screw issue is the same... I jused a slightly longer screw, with the same locking nut on the back to secure it to the shock tower, but the issue now, is that when you use the factor 22 shock bushing, it pushing the shock TOO far back, and the shock spring will bind on the camber link. However, there is no clearance issue with the shock tower. So all I did was bust out my sand paper, and file down the thickness of the 22 shock bushing. So instead of there being like 5 or 6mm of "standoff thickness" on the side of the bushing, I have about 1mm. (you can see the difference in width in the middle picture below)

lower mount:
The shock is still a tad close to the camber link, so the bottom just needs to be shimmed out a bit. I used the thicker 2mm blue washer from the link posted above, and clearance is perfect.

Springs/Oil:
I did a bit of testing to determine which spring rates are needed for symmetry in rebound rate between the front and rear of the car. Considering the front of the car is much lighter in the front compared to the front of the 22, it was no surprise that red/F and yellow/R wasn't a good match. it was too soft in the rear. I ended up with red/F and pink/R. What piston and oil you run from there, is up to you. I am running 56 pistons with 25/F and 20/R.





Nice writeup, thanks for taking the time and effort to do that.
