I would like to rebuild the front suspension on the Formula with poly bushings, including the subframe/body mounts. What kits are available, and what is included with them? I would also like some feedback on how this affects ride/handling.

Most companies offer complete kits. This should include bushings for: lower a arms, sway bar and end links, trailing arms, center link, rear sway bar and end links. Thats the basic. You could also get motor mounts and a trany mount. When buying for a full frame car you get body mounts. You also want to get strut tower mounts if possible. This may not be available from a poly company.

 

Thanks nicmike85, I guess I need to research the different kits offered by different manufacturers. I am open to suggestions.

I have heard the polygraphite kits are better than the polyurathane. They are supposed to be quieter. I have run polyurathane motor and trans mounts and I am quite satisfied with them. You can feel more engine and drivetrain vibrations but I like to feel a performance car. At first it felt strange but now I can't even tell. Guess I got used to it.

 

just did the front end with PST's kit and it made a full 100% improvement in handling. I am really amazed day to day at how much tighter the car handles. and it also seems that when I go over bumps and such now the car actually absorbs them better and doesent reverberate the shock through the body of the car. I have driven 90's Vettes that did not handle half this well.
