E30 Shock Option Thread

[drumsauce]

Year later bump, but for the good of the thread, I emailed Koni as well about the actual measurements, looking for a shorter shock in the rear than the Bilsteins currently allow because air bags.

(Quote): The 8041 1186sport and 8042 1134sport are the same length and are the shorter of the two. They measure 503mm extended, and 321mm full collapsed metal to metal. With the bumpstop installed, the stop begins to contact at 372mm collapsed. (end quote)

1186 and 1134 are the mustang rear and made from the same shock body. 1186 is the single adjustable and 1134 are the double adjustable.

1186/1134 lengths:
Extended: 503mm (19.8")
Compressed: 372mm (14.6") w/bumpstop
Compressed: 321mm (12.6") w/out bumpstop

And while I'm here, I've been trying to find the difference between the two rear Mustang Koni options and finally decided to send Koni an email. Here is the response from a Koni rep:

The 8041-1026 Sport is shorter by 5mm in compressed length position, however it does not use a bump stop.
The 8041-1186 Sport does have a bump stop installed from the factory which makes contact with the shock body 50mm before full compression is reached.
The dampers are valved exactly the same.

^I'm planning to use a piece of smaller OD steel pipe under the insert, maybe weld a plate to each end to close it off (but probably too lazy for that)

Not sure how this impacts the oil/antifreeze in the housings they bmw/koni use for heat transfer. Seems like the oil would just drain down into that void, but I haven't heard of any problems from this?



And while this thread seems to have been abandoned, I'll say that Koni 8610-1437 Race are a good/stiffer alternative to iX konis, and will work with a stock (Non-Bilstein) Gland nut if you shave the bottom of the nut down 1/8" so that it contacts the body of the shock before the outer tube/cover.

I have a question about using the iX struts up front. I plan on getting the Koni's but Im not at the point of sectioning the housings and going full coilover yet. I have IE3 springs so the whole unit will be more compact, but I thought I read somewhere that I would need a spacer or something in the housing itself to fill the gap between the shorter strut and the original housing.

So my question is what are you using for a spacer?
AND
Should the spacer go on top of the strut or underneath the strut?

I've had the KYB AGX 8-ways for the 87-93 mustang in for a few days now. They are a direct bolt-in installation. And the droop is 16" from late fender to the center of the wheel. As far as driving impressions, I set them at 3 out of the box and they drive very well-controlled and not harsh at all. I was concerned that they felt soft before install but they are great on the road. I have H&R sports. I have my Feont Konis at about a turn and a half from soft and these are about even at 3, maybe just a bit softer. Will try 4 and above tomorrow.

Any confirmation if the Mustang Koni 8041 1186 SPORT rear (Mustang 94-04) is going to work in the E30 rear.
This thread says that they have used it and it seems they use the same rear as E30.

Confirmed that 12mm rear shock mount is required. stock is 10mm.

I can get 60% retail on Koni's. What should I go with? I plan on dailying the car with occasional track and autocross days. Suggestions?

My concern is whether my konis have a 10mm or 12mm shock pin.

edit: Tried pulling the nut off the top of the rear shock to measure the thing, difficult in the dark though. Browsing around the interweb I found a pic of what mine look like though... from my understanding my rears konis are the hydraulic adjustable.



another edit: Called up UUC and found out that the meyle HD rsm kit fits the konis... and they're prices are ridiculously cheap compared to bavauto

I'm using the IE alum/poly rsms. Had them since about this time last year and I've had no issues while running H&R Race/Bilstein Sport combo.

[e30slidewayz]

Quick question... I need to order some rear shock mounts. I'm thinking of going with the meyle HD set UUC offers. I'm running e30 koni yellow adjustables, will the shock pin fit these mounts? I was messing around on turner and saw that they have an aluminum version that takes a 12mm shock pin that they say fit most koni shocks. The only thing is they cost twice as much. Hoping I can get away with the UUC set. What you guys think?

Here is the skinny on IX inserts.

P/N-----------------Avg $-----------

Koni: 8641-1144Sport--------$170
Bilstein: P36-0251-------------$110 shipped each @ autopartswarehouse.com

Both come with lifetime warranty. Konis are SA, which is nice. Bilstein is less expensive to buy, rebuild, and revalve. Bilstein is also easier to exchange on warranty thanks to http://www.bimmerparts.com/ (just order a new strut, once received ship back the bad insert, they will refund your payment for the new insert. Essentially warranty costs shipping two ways, but it is a very simple process)
