MM uppers, huh? Got a link?

I bought them from SVTP but the poster already deleted the image from his Photobucket.

I did a quick google and found them in a cached picture, the one on the site it links to is down also.

They are red with spring perches for my non coil over rear. Grease fittings for each bushing and they are urethane iirc.

I snagged them both (uppers and lowers) shipped for $140 total which is a hell of a steal. They are brand new never installed. No scratches or anything.

OHHHH - MMR. That makes more sense. You had put MM, which in my head is Maximum Motorsports, and I was confused as they don't make a UCA.

All is well in the universe now

lol yeah I meant to put MMR. Sorry bout that.

So is that a deal or what?

Looks like those uppers are poly bushed. You're better off with your stockers.

I can't tell what the lowers look like in that pic, but those alone sound worth the money you paid. Sell the UCAs off to someone that doesn't know any better, and call it good.

[acidtonic]

My stockers are practically destroyed from hard launches.

As in the rear literally moves a good 2-3 inches laterally now. The bushings used to hardly move at all until the end of summer when I beat on it a lot more.

The way it is now it's not too safe for high speed driving since its really "wandery" and doesnt want to keep going in a straight line.

Getting on it and the car wants to jump to one side, let off and the car goes back to the other side, get back on it and it goes again the other way. It's not safe and it's getting hard to keep it going straight under acceleration.

I also dont run a rear sway bar since it broke off and the car rode fine without it. Now that these bushings are shot though I wish I still had it.

Also I recently had a full front end alignment when I replaced balljoints and tie rod ends but that didn't really help much. It's obviously the rear swaying.

That's all well and good, but poly bushed UCAs aren't going to solve your problem. You either need to replace the rubber bushings, or get some UCAs with spherical bushings in them. Reason being that the axle-side and chassis-side UCA mounts do not stay parellel during suspension travel; there's some twist that has to occur. Rubbers allow that via deflection, sphericals allow that through freedom of movement, polys fight it like a bastard.

[acidtonic]

So the lowers are fine but you suggest a spherical for the uppers?

Being a little strapped on cash do you think it's a huge deal like night and day, or just a little bind here and there? I haven't read much about the 4 links, I've been thinking I wanted to go 3 link + watts or delrin bushing IRS. Anything is better than it is now. Feels really rickety like the rear will just fall off and leave the trunk sliding down the freeway.

Car went from being my DD to the weekend car. NVH is now completely out of the picture and she will be getting gutted even further.

I know 140 shipped was a deal for those arms, but you really think I should sell the uppers and go spherical?

/me goes to read some more.

Honestly, I've never ridden in a car that had poly bushed UCAs. I'm relaying what I've read from multiple places coupled with my understanding of the geometry of the fox triangulated 4-link suspension. Don't get me wrong, I *know* it's bad, I just don't know how bad. My guess is that it won't seem that bad (maybe a little jittery) until the first time you hit a pothole, and then the lack of suspension movement will rear it's ugly head.

If you're strapped, and this isn't a drag race car, I'm honestly getting more and more enamored of the IRS. Maximum did some testing with one, and they describe it here: MM IRS Q&A. I've heard of take-off IRSs going for as low as $100 for a complete unit, you might even be able to make money if you trade your SRA to someone for their IRS.

The only concern I would have is I know you're hardcore about weight reduction, and the IRS is going to add something like 85 lbs to your car. The good news is that that weight is low, back, and sprung, so it should actually make your fore/aft weight balance better.

With as little weight as you have, and stock power, you could go with a '99 unit to save even more money, and just do the suggested reinforcements.

[acidtonic]

I too have caught the IRS bug.

I know Solids are better for smooth track conditions, but lets be honest here. I street the car and it's in Michigan with the worst roads I've ever had the pleasure of driving on.

I think the IRS would be a great match for my car if only I could find one where the owner didnt want to screw me on a trade.

Ideally I would keep my solid as a spare, then drive the car like it's meant to be without caring about damage.
