This weekend my son and I installed this bushings kit from FT86 Speedfactory
http://www.ft86speedfactory.com/perr...combo-435.html and it took about 2 hours on our backs with the car on Jack stands. 1 person could do it but 2 makes it a lot easier.
I didn't remove the FP, but I disconnected the rear part of it from the MP. I also didn't remove the underpanel I just removed 3 bolts and bent it aside. You need a set of sockets and some extensions but not much else. I'm no mechanic but I'm good with this sort of thing; my son doesn't know a socket from crescent wrench. So anyone can do this mod really.
I expected a lot of gear whine but there's very little extra. There's a little more general noise and vibration in the car but not a ton. This is the most subtle mod I've done to my car. One caveat is that my exhaust is pretty loud and I already had a lot of vibration so YMMV.
Shifting is better and a lot tighter but but not like a short shifter kit tight. There used to be a lot of slop shifting into 5th but this mod took care of that. Also acceleration feels different which I didn't expect and I can't explain. It's subtle.
So far after 200 miles I love it but it's not a huge change. I'd do it again considering it's a cheap mod and FT86 speedfactory has excellent service.
