To prevent wheel hop we replaced the rear differential bushings with these hard urethane parts (part number KDT924). Whiteline also has inserts that are easy to install but we opted to get rid of the rubber all together.
We replaced the differential nose bushings with Whiteline urethane as well (part number KDT923).
The only stock suspension link remaining on our car is the upper control arm. It is a cast piece with elaborate bends to clear the frame rails. It is very hard to fabricate a part with similar geometry so the aftermarket hasn't come up with an adjustable replacement. We needed to make the camber more positive for what we wanted to do so we used these really cool Whiteline eccentric urethane bushings to make the upper link adjustable. We also use these to make other adjustments to reduce body roll which we will elaborate on later.
To do a full bushing replacement you need to drop the entire rear crossmember which is a lot of work. Whiteline's insert bushings do not require this are and are a lot easier to install but we wanted the performance of full urethane.
Pressing out the stock subframe bushings was pretty difficult. Technosquare's Howard Watanabe and Mike Kojima are grunting and cussing on the hydraulic press trying to get the bushings out. It took the presses full capacity and when the bushings broke loose they made a loud popping noise.
Howard uses an air chisel to punch the differential bushings out of the subframe. This was pretty difficult as well. Howard had to use an air chisel because it was impossible to reach these bushings with a press.

Hi Mike
Have you done any projects on the 06-11 Civic FG chassis ?
Would like to know what’s best for a better (already good stock)
road response for not too much outlay
Thanks much.

I did the Spoon FT2 which is like the FG. What is not a lot of outlay, that’s a very general impossible to answer question.
What are your thoughts on the combination of the 22mm and 18mm swaybars? I noticed that whiteline is packaging the 22mm front with the 16mm rear. Do you have any insight as to why they may be doing this?
