Anyone know where I can get the complete kit or be able to purchase individual pieces from that kit BESIDES Rallispec?

Vermont Sports Car sells the complete kit. They also carry motor and tranny mounts if interested. Their site is http://www.vtcar.com

are bushings really that important to change?

Anyone feel free to correct me if I'm wrong but I would say the importance of changing the factory bushings would depend on your intended use. In a rally situation where your punishing every aspect of your car I would say the Group N bushings would offer greater durability. They are also very limited to exactly what motifications they can perform to their car, hence the Group N name, which means they are homogulated for Group N use. Since they are so limited they will typically make every improvement to the car allowed by the rules. These bushings would also offer greater stiffness in relation to the chassis. Initially your money would probably be better spent on a more noticable improvement especially if you have not upgraded anything else on your car, unless you are competing at such a high level where you will notice the difference. I hope this answer helps.

bushings do make a difference if you get all the bushings changed to group n or urethane
