Whose got the best deal on Konis?

[BDK]

I thought I read a post that someone carries rear adjustables that are adjustable from the top like the fronts, is this true or was I just dreaming...

[Mossman]

Search around for mustang konis, I think that's what people use if you don't buy them from klein or GC

if you give me a part number i can see what i can do!

I think I had BMA price match Shox.com for mine. Shox.com had a quoted 4+ week delivery time and is known for poor service. BMA had them to me within a week. Best price and excellent service.

[xLibelle]

I bought mine from an ebay suspension shop for 520 shipped i believe

Koni rear

Koni rear top adjust. The prices on these went up in September, so be careful if you are internet price shopping. A lot of people just cut and paste catalogs and haven't done the new prices yet.

For a Mustang, the lowest price any authorized dealer can sell for is 134.06 each.

Because Ground Control is both an authorized Koni dealer and an R3V sponsor, I will include shipping AND I will include actual shock dyno sheets to help you dial the car in. Also, the warranty will be legit.

I do not know if this is the cheapest deal, but I have tried to make it as attractive as possible within the bounds of my agreement with Koni.

PS. GC has the Konis on the shelf, ready for shipment. The fronts are now $193.80.

when you say mustang, you are talking about the ones that work with our cars correct?

Yes, there are three different Mustang rear shocks, any will work on an e30, but two have valving that is 50% of what you need, and the other is about 65% so it works a little better.

When I say 50% I am not talking about spring rates or anything like that. The Mustang has a solid axle that is very heavy, and the valving is designed to work around that. (remember the shock valves work when the suspension moves up exactly as when the car moves down, so thats what I am referring to.). The valving is different for a heavier unsprung weight.

The e30 has a rear suspension that is 10 billion times more sophisticated than a Mustang, so the shocks for solid axle don't work as well as shocks designed for independant, however it usually more desirable than pulling the shock to adjust it. (But if you are REALLY into it, the e30 M3 arguably has better valving but you cant adjust it from the trunk.)

By the way, any of the Koni top adjust rear shocks including the GC ones that are actually designed for the e30 rear suspension have a 12mm top pin (instead of 10mm) to retain strength. This requires drilling that is not fun or new aftermarket upper shock mounts. Although e30, e36 and e46 rear shock mounts from BMW are interchangeable, all of them are for 10mm.

Hope this helps.

What's the pricing of those trick short Konis for the front? I have a dead Koni and need to replace the pair pre-season and weighing options. (And unfortunately don't have the receipts and all)

If the difference isn't great, maybe. But purpose is just DE-ing... maybe eventually TT, and slamming the ride isn't necessarily important, so I may have the my M3-type tabs welded on and call it a day. (But the GC adjustable sway bar links would be a good fit though, right?)

This is a quick reply, just to clarify, and to make sure that this thread does not turn into another fountain of wrong.

Post dyno graphs.
Because I have some that show the Koni for a Mustang and "special E30" almost exactly the same.

Whatever dyno graph you are referring to is wrong.

The GC e30 shocks are designed completely different than what Koni designed for the Mustang, they have different Koni internal parts, valves and codes, and virtually not a single part in common with the Mustang shocks.

I'd even be willing to bet that the difference is in gas PSI so as to save Koni the work and everyone selling "special shocks" the costs.

You would lose that bet.

Besides that, it wouldn't save any money, and gas pressure is an incredibly small factor anyway.

A mustang has a solid rear axle and more unsprung weight. The compression damping is stiffer for the Mustang.

Completely backwards. The Mustang shocks are valved by Koni to be comparatively soft to reduce the influence of the unspring weight of the solid axle. This is the same approach as Bilstein, Monroe, KYB and every company who designs shocks for solid axle cars. There are other differences too, not just valving.

Everything else the same.

100% incorrect.

This post is not an invitation to an argument. I have posted truthful replies and corrections, in order to slow the spread of e30 misinformation, for the benefit of R3V.

Koni lowest advertised price allowed for the 8641-1198 sport is $193.80.
The Koni short struts that I designed for the e30 we sell for $183.00.

Triple check the dead Koni. The last FOUR warranty requests I had were Vise Grip victims. So triple triple check that it is really dead.

The uber cool ones are cheaper? Neat.

Yea, the shaft fell like a rock if I let go while trying to re-install my GC's/plates. And yea, the shaft is abused - at least after the nut was seized inside the stock upper strut mount and conventional technique wouldn't work (and warranty was already out of the picture).

The insert also wouldn't come out when I tried to swap housings previously, so I'm figuring just nab housings and inserts and get it all together.


But it might make sense to have GC modify housings and add the tab and install short inserts and have them arrive ready to go (under my springs and plates) vs. buying OTS variety and having the local shop weld on tabs... but shipping may be $$$.

Post shock dyno graphs.

Umm, the word "proprietary" springs to mind . . . .
