I'm about to buy the same thing. Hopefully next weekend.
I have the Ground Controls with AGX 8-ways. I used the OEM bumpstops uncut. With the car as low as it is, the rear suspension always hit the bump stops. The FM rear shock hats took care of this problem. I never hit the bumpstops and they are still uncut.
My ride is firm and can be a bit bouncey on the street but many drivers feel my car is very nice on the track. (Merv and Gary both have driven my car and commented on it.) My setup is not nearly as nice as the Tiens probably are but when I got my setup, the Tiens were not readily available.
If ya'll still wanna do a shock install tonight I have some AGXs and JR springs sitting in my room wanting to be put in!
