Koni NA - Big Thumbs Up!

[Moto-Mucci]

Anyone have the part# for those bump stops? Are they stock? My car never had them.

I had a leaky rear Koni SA shock with my Ground Control setup, so I called Koni NA to send both rears to be revalved for my spring rate.

Great experience! Repaired the leaky shock, revalved for 1000lb springs and repainted the bodies - they look brand new. All in a 2-week turn-around time. $234 for the whole deal.

What front rate are you running? Somewhere around 800?

do you ever post anything worthwhile?

It's a sticky because there is contact information that you could use to get your shocks rebuilt.

lol;)

I discovered today that I have the exact same problem. One of the rears is leaking badly and I am not the original owner. I called Performance Shock Inc. and he is going to check with Koni and see if they can cross reference the shock. Koni's from GC have their own part number and are specific to GC. God knows I dont want to have to deal with GC if I dont have to. I'll update this post when I get an answer along with PSI's contact info.

Good times...

I should mention that I ended up going through GC and they were EXTREMELY helpful. Warrantied the bad one even though I was not the original customer.

Thumbs up to GC's customer service.

Bilstein will also rebuild and revalve any shock to any spec. I think rebuild is $60 per and respec is a few more $$ since all they do is change valve body during the rebuild.

Well, I ended up just buying new from GC. Word to those of you that are interested in getting your Koni's rebuilt from Koni, the warranty is only 6 months.

Fred - Keep in mind that shock valving has a HUGE effect on ride quality and harshness, much more so than spring rates.

Cool. I am going to run J-stock suspension, and the damping and spring rates are pretty high, though the springs are progressive.

I stickied this thread so I people who want to have their konis revalved/rebuilt don't have to dig for the contact info.

[Teaguer]

Thanks for the info , that will definitely come in handy .
Now I just need to figure out what spring rates I want to run . :???:

[Mike B.]

I just run stock E30M3 sways, that can be disconnected depending on the track. I am a proponant of less bar and more spring to help with lifting the inside rear tire.

I don't think 1000lbs is too high as my lap times indicate the opposite. Heck, the Grp. N factory dry setup is 1142lbs front and 1368 rear and I've also seen an 800/1143 Grp. N setup as well.

Teaguer - These were installed on the car when I purchased it last February, and I had no original documentation for the shocks. I think they may have been 2-3 years old. I don't think you will have any issue with what you have to be rebuilt. My contact was:

Stereo - The shocks were fully rebuilt (along with the revalve) as one was leaking oil like a sieve.

[Teaguer]

This is good to hear as I have a set of E36 front inserts and two pairs of E30 rears that I need to have rebuilt as they are leaking .

Sure I knew they offered rebuilding but I wasn't aware of the costs and I did'nt want to have to send them back through GC, so I was actually considering in buying new ones eventually .

Mike , how old were they when you sent them back and were the original purchase records needed ?

[StereoInstaller1]

Hey Mike, sounds like a happy deal. Since that was a "revalve", did you ask about a full rebuild?

Sure is nice to hear of a company that takes care of its customers AFTER the sale!
