Not debating doing the rear sub frame bushings...that's a given...just the bushings I use.

I am definitely not looking to cut any corners, going through the trouble of doing this I definitely want to do it right. That said, saving a few bucks isn't worth it if it's a compromise. Inserts are not an option, don't see why anybody would want to add those to their worn stock each their own.

It seem as though the Powerflex are over priced, possibly due to lack of competition? However, if they are superior then so be it.

I'm curious about the holes in one set of the Prothane bushings that can be seen in the picture above, I wonder if this was done for vibration or to soften them up a bit?

As for them being two piece, dunno :shrug: maybe so energy (vibration) isn't tranferred through a 1 piece bushing? Powerflex is pretty popular and gets good feedback and rears are one piece and fronts are 2 piece.

...and yes, I plan to track the car...first track day is March 8th.
