derling bushings
 

Sup guys?! Am in need of some new bushings and as looking into the super pro but unfortunately they don't make them for the FC. I have been browsing and have come across these bushings made by Derling. My question is has anyone tried them on their car? Here's the link...

If it's a street car stick with the polyurethane bushings. The suspension system is bombarded with vibrations while the car is moving. The stock bushings are designed to reduce those vibrations a significant amount. Polyurethane transmits more vibration to the chassis but still dampens out the "hard" vibrations, or the damaging vibrations. Delrin on the other hand begins to transmit some of those more damaging vibrations to the chassis; which if in use on a street car can, and most likely will, lead to stress cracks at the pickup points and eventually mount failure. Delrin bushings should be kept to the race cars, or the street cars that aren't really street cars.

You can however use Delrin bushings on the subframe. It helps keep wheel hop down and doesn't transmit (perceived) vibrations to the chassis.

My car is for street, not a daily driver. My bushings are in pretty bad shape and need to replace them, so i would like to get something better, that will increase the performance of my 7. I don't want my ride to be too rough either... What do you guys use for after market?

Poly bushings. Energy suspension sells a master kit which works quite well.

If your old bushings are shot, even a fresh set of the stock bushings would still be an upgrade. Since you're going to be driving on the street, you ought to consider the quality of the roads in your area before you buy the 'upgraded' bushings. Harder bushings in general mean a harder (read: harsher) ride.

I live in the NJ/NY our roads suck azz!!! there are more pod holes in any NYC street than any other street in the US (maybe except PR) :rofl: luckly i don't drive my 7 daily and try to avoid NYC whenever i go for a drive :suspect: Jersey roads are avarage... I don't want bushings that i'm going to be able to feel every part of the engine, trans and diff, or put stress on the chasi of the car... I'll look into the energy suspension, but i was told that their products are not of good quality...

have you used that kit, i was told that their quality is not good?

Mazdaspeed bushings, mazdatrix sells them i think, maybe corksport.

Neither one has them, if you know of a site let me know... I'm going to ask kg parts see what they carry...

Yes I've used them, as have a majority of owners from what I can tell. The ride is a little stiffer, but compared to worn out bushings they're amazing. Have not had any problems with them what so ever.

I have energy suspension bushing on the '91 and will soon be installing another set in the '86. I like them and think they perform well (although neither of these is a race car).
