If 4 of these 5 members buy in, we are definitely on. Anybody waiting to see what will happen...there you go. Once these members make payment I will place the order for the molds. I will continue to take orders for bushings until the molds are delivered which will be approximately May 11. At that time I'll have to place the order for the poly.

Right now it looks like we will be moving forward. Nd4SpdSE and hgallegos915 are the only ones on that list I think who are undecided.

I am interested, but am not entirely sure of the durometer to get. My ride is already prety harsh. Maybe 80A fronts 70A rears.

Any coments on this would be appreciated.

[fowljesse]

Someone correct me if I'm wrong, but I don't think the hardness of the bushings will not affect the harshness of the ride. The only potential affect I foresee is; if you have too soft of bushings for your swaybar, like I may... I'm getting 70A bushings, and I have the Whiteline 22mm swaybar with hard swaybar bushings + solid endlinks, so I suspect that it may have a "waggle" when I hit a pothole, since it'll pull up the other wheel.. It's hard to explain, but it's not a big deal.

[wytbishop]

No, Jesse. The firmness of the bushings will definitely affect the softness of the ride. The bushings are there specifically to provide a cushion between the rigid suspension parts and the even more rigid chassis of the car. So when the wheel hits a bump in the road that shock is absorbed by the bushing and (mostly) not transmitted through the chassis to the driver.

As far as what you should get Rece... I think there's a fine line between a car that feels tight, and a car that feels harsh. My personal opinion is, unless you're going to try to be competitive on some level, 70A is going to be perfect. Some people prefer a ride that is a little harder though, so maybe you're one of those guys. I would not recommend 80 for the majority of street drivers.

Also, I want to be clear that my "hypothesis" about the active rear suspension being tied to the stiffness of the bushings is only hypothesis. I make no claims to understanding the intention of the Mazda designers. I don't want people complaining later that I told them to buy this firmness or that for a particular bushing. I have never done that. Any experiments you all try on your cars is your own idea and attempted at your own cost and risk.

[rece]

point taken, Maybe the 70 all around wil be better suited for my car and ride preference. I will get you the deposit as soon as i can, and before the deadline if no issues come up.

[Nd4SpdSe]

I'd get the 90

[fowljesse]

My car has H&R springs with Gabriel struts, and the hardest Energy suspension bushings available all around (I dont know the durometer), and it's less harsh than all the other lowered MX-3s I've ridden in. It could be the struts
It's a very tight ride, but the RWS doesn't move much.

[wytbishop]

Well a good spring/shock combination will absourbe the bumps in the road preperly that's for sure. Butt he bushings are intended to absourbe the "shock" loads. While your ride is probably nice and soft, I'm betting you feel a fair bit of road vibration. You're probably just used to it and don't really feel it anymore.

[Mooneggs]

(Mooneggs hops off fence) payment sent for 2 rear kits!!!

Right now I'm thinking 70/80 durometers for the DD and 80/90 durometers for the race car... Wytbishop - maybe you could list the durometers everybody is requesting? I'm still unsure if mixing them is the way to go... but it seems like the bushings in the arms should be a little more flexible

[onlytrueromeo]

I posted a link to an article about miatas. Most of what is available for Miatas is 80+ Durometer. Everyone talked about how much it improved their ride, some even wanted a harder durometer. I did not want the extreme 90A, but felt the 70 was too close to stock for me (stock is around 65 I believe) I chose 80 because I felt it was a good mix between the 2, and from reading on other forums, most poly bushings are at or above 80 durometer. I have the 80 durometer AWR engine mounts, and I do not notice/mind the vibration coming from the ENGINE. I don't think vibrations/resonance from driving will be uncomfortable to me. Anything will be better than the terrible ride quality of my worn rubber bushings. I think a harder durometer will transfer the small imperfections in the road more, but will not come into play much when hitting a big pothole. The only time I think they'll be annoying is when driving over hatched concrete and possible going over bridges, the only times when small imperfections produce extreme vibrational response in suspension.

I'm amazed this isn't going faster.

Is it .. considered legit .. to start one last new thread titled Group buy for polyurethane bushings needs <x> more participants! in case people stopped monitoring / aren't noticing this thread?

I can't believe out of our entire community we can't find more than this many people who want to take advantage of possibly the last chance to buy such critical custom suspension components like this..
