Anyone try these coil-over sleeves?

[1991 318is]

Where oh where were my coil overs made?

What'd you have to bore those centers to? I've a buddy that works at a machine shop that can probably do it for next to nothing.

Open them up enough to fit over the raised locating area on the trailing arm.
I checked those springs on a spring checker and they're just 2-3 pounds short of 350 and 450 ( within Eibach's tolerances). I put the 450's on the rear. They are still going two years later.
In almost 30 years of racing sedans on oval and road courses I have never seen a failure of sleeves or adjusting rings.
I wouldn't be surprised if most of them weren't made in third world countries or in Eastern Europe like my Bilsteins. Most coil over kits are repackaged with springs by the retail sellers. I'm curious where most of them are originally manufactured.
Coil overs are a dick dance for the street. I got over them pretty quickly.

Well I have those $100 knock off coil overs on my car, but basically the only thing I'm using from them is the springs, and the rear threaded sleeve. I had to do a LOT of modifications to make them fit and ended up buying new front sleeves similar to what Ireland sells for the fronts and new rear spring seats for the rear. I've had them on the car for over a year, and the car has seen track duty the springs do great for an e30 if the rest of the car is setup correctly(mine stays flat)

That picture was taken mid way threw turn 1 at Road Atlanta

Notice it's people with actual experience with them that praises them and people with no experience bashes them? :P It's the way it is with every cheap product on eBay, the only thing i wouldn't buy would be an eBay turbo, i have talked to people with experience that blew them due to a bad balance, but some had ran them for years.

What issues did you have with fitment? Why did you change the rear later? What issue did you have with the fronts? details details details!

Haha, i was just curious because i'd likely take them to a machine shop with measurements and tell them to bore to that. I don't mind the ride, roads here are pretty good.

well for the front sleeves to fit over the bilsteins I had to completely open up the center and remove the flat portion that was at the top. But then once I got them to slide all the way down the strut housing they were too short, I had the adjusters almost at the top to get the height I wanted. So I ended up buying new sleeves that were over 1" longer(allows for more adjust ability).

In the rear I had to open up the sleeve a ton to fit over the nub on the trailing arm, plus I drilled holes threw the trailing arm so I could run a large bolt straight threw into the sleeve from the bottom(to keep it in place as they didn't fit very well on the nub till I removed a lot of material).

I was planning on just resting them on the origional spring purch. I have some other sleeves laying around, maybe i can make something work.

We used a kit like this on my brothers car.

In order to do it properly we did this:

1.ordered cheapest kit on ebay :) $38 shipped

2.threw away springs which were way out of spec

3.cut stock spring perch and installed front sleeves after cutting them to length.

4.ordered eibach springs 400lb front/550 rear. all 6" long

5.installed fornts with Ireland camber plates and Bilstien sports

6.install rear springs without adjusters. just sitting between the two nubs like stock. Bils sports were used in the back too.

The rear has no adjustment, but the ride height is perfect.

I have a full ground control setup on my car and consider it money wasted compared to this setup.

YOU MUST USE CAMBER PLATES AND SUITABLE SHOCKS. Otherwise it is a total ricer hackjob.

Yeah, read the description, 450 front 350 rear.

Please allow me to chime in. This is the equally cheap kit as sold by another brand x eBay retailer located in Montreal: Cosmo. I saw that kit at a friend's shop. My friend (57 year old BMW specialist and racecar builder) was scratching his head trying to install the kit for a client. Pure shit. Also, with the 450fr and 350 rear spring rate, expect some MAJOR understeer. As a rule of thimbs, on e30, the rear rate should be 150% of the front. So, if front is 450#, then rear should be 675#.
