Bushings?
 

What mileage did you replace your suspension bushings with, and what brand did you replace them with?

I am replacing all of mine on my rx8. the rx8 I purchased and has 129K miles.


All of the stock bushings have major wear, the rear differential mount bushings were completely destroyed and was probably causing shifting problems in the transmission (speculation as of right now, and hoping) and it also felt like the rear wheel(s) were out of balance.


I replaced all of them with Whiteline bushings except the rear front bushing which is not offered by Whiteline, so I am replacing that with Superpro.


Whiteline and Superpro are the best bushings on the market as they are chamfered and built correctly for smooth operation, energy suspension bind some and so do powerflex. I run Superpro bushings on my rx7 FD and am very satisified.




Tips for removal.


everything is straight forward to remove the front of the suspension. in the rear the rearest lower control arm you need to place a long socket over the rod end and hammer it out. The others are like tie rod ends and you can hit the side of the knuckle to release. there are 5 multi-links. Whiteline is kind of confusing on where the bushings all go but they are all different sizes.


The car is still down for winter as I am updating the entire car with things that are going bad, but I am hopeful that these bushings will make a LARGE difference in handling like they have done on my Honda civic, Chevrolet aveo and FD.

How'd the bushings turn out? Thinking of doing the same thing.

car handles great now that the bushings are updated. whiteline feel and ride great, no noises at all. driveline feels super solid. I used one superpro bushing on the front lower control arm where whiteline doesn't offer it.

If you need new bushings then you also always need new suspension arms too

Again it's my assertion that unless you change to heim/spherical bearings for racing that most of the OE suspension arm bushings are superior to poly bushings. The OE bushings have internal steel inserts that limit deflection. Most people think they're just soft rubber and that's not the case on the RX-8.
