    These parts have done well for me. It was absolute misery removing the old bushings though. Just dont forget to put on the supplied bushing grease or they will squeak all the time.

    Zachary Kuykendall - . Energy Suspension 11.18101
    So far so good. Definite difference in handling. Awesome for the price too.
    5 out of 5 - A+
    Thomas Hyland - . Energy Suspension 11.18101
    The rear bushings didnt fit correctly, I had to cut the steel bushings for the rear in two, more like the stock configuration to get them to install correctly. The tie rod end bushings were missing and one of the end link bushings is incorrect. The instructions are vague as well, although as a mechanic i was able to figure them out.\nEditors Note: It is very important to read the instructions fully. In some cases the instructions are very simple and not explain fully. If you have any questions call Dst. If we can not answer the question we can supply you with Energy Tech Support.
    1 out of 5 - poor

    5 out of 5 - Very good
    Simon Cuartas - . Energy Suspension 11.18101
    Highly recommend these bushings. I was very happy with the quality of the bushings. They come with easy to read instructions and plenty of bushing lube. Also great price and fast shipping.
    5 out of 5 - Amazing!

    5 out of 5 - PERFECT
    JASON BOVIA - . Energy Suspension 11.18101
    Quick and easy to install. Clearer direction would have helped on rear assembly.
    5 out of 5 - Quick delivery and product could however use clearer directions
    Terry T. Peirano - . Energy Suspension 11.18101
    This kit was exactly what my RX-7 needed! I was able to replace almost all of my suspension bushings with this one kit, and at an awesome price too! The only thing that could have made this kit even better is that the stock ball joint and tie rod boots are sealed, where as the ones in the kit are not, and do not fit as snug or well as the stock boots. If the ball joint and tie rod boots could be made to fit more snug, or even be sealed around the tie rod and ball joint ends, this kit would be the absolute best. Even with that, I still rate this kit a 5 because of the exceptionally low price you pay for such a complete kit!
    5 out of 5 - Awesome suspension kit for the price!
    Taison C Wilson - . Energy Suspension 11.18101
    Good price / highly recommended.
    5 out of 5 - Nice Product / no noise / like on rails
    Don Barringer - . Energy Suspension 11.18101
    Parts were easy to install. Took all the slop out of the suspension and stiffened everything up.
    5 out of 5 - parts were just what the suspension needed
    Earl Cunningham - . Energy Suspension 11.18101
    I got these bushings because my stock ones on the RX-7 were way past worn out. The stock bushings came off fairly easy with the included instructions, and the new bushings slid in quite easily. The one thing I think would be nice is if Energy Syspension sold just the front end kit. The second Gen RX-7 has binding issues when the rear control arm bushings are replaced with urethane, and this affects camber adjustment. Also, a lot of people don't run a rear sway bar on these cars, so I didn't get the chance to use those bushings either. The rest worked out really well.
    5 out of 5 - Good.
