Koni Yellow Whoes :(

[fooddude]

First time I've read about this. I guess Koni shocks will be crossed out off my list.

I was also told bottoming out the konis can also do this. Which makes sense considering the pot hole nightmare my town turned into over winter. @Racecomp do you remember how much bump travel is left when using your bump stops from the yellow springs? I'm still using those with the tarmacs as I assumed they were the same.

I just installed Konis, so I'm understandably concerned. I'm presuming you're directly tightening the top mounting nut since it looks like you're maintaining the stock top mounting plates? If so, how are you tightening / loosening the nut and any idea what the tightened torque is? I purchased an assembled set-up so I only needed to mount the pre-installed top plate to the strut tower. I'm simply curious as to whether that might be a meaningful difference, or not.


Thanks.

Those are pics from last summer. I no longer run stock top hats or whiteline top hats. I have adjustable camber plates from HVT

I've been running Konis and RCE Tarmac springs for a month now. So far, one of my rears leaked a tiny bit on day one but haven't leaked anymore since then. I do check them every few days though. Hopefully you got all the bad ones so the rest of us get the good ones (Just kidding!)

I hope this thread doesn't turn too many people away from konis. So far, I've been really satisfied with them and they are definitely an upgrade from OEM dampers. I would also say to try full stiff once... and then never again (unless you like bad massages)

Also remember to grease the koni to rear LCA connection... took me a week of severe squeaking to figure that out.

I am not a fan of koni..... My 1st race car had koni's.....they wore out silly fast and provided almost no damping, especially rebound damping...car was all over the place.

I am impressed with bilsteins....much better quality....especially at their price point....

How are your HVT plates as far as noise? I have them too and my front end sounds rattly/loose from day one. I'm 99.9% sure it's not the camber plates, but figured I'd ask.


I've never seen Koni's crap the bed in such rate. I've run nothing but Konis on my car till now and never had any problems. All were autocross cars too with nearly 25000 miles driven to out of state events.


If you're running bump stops, I don't think you're bottoming out. It feels like it, but it's the bump stop. Your first picture reminds of that other dude with Fortune Auto shocks, that failed in that exact spot. I wonder if it's something about our cars that puts that kind of side load there.

My hvt plates are good. Make sure that top nut is tight. For about the first week or so it kept loosing. Also big bumps you get some shock from the metal on metal contact.

Rantoul is a rough surface for autox one of the more choppy I have ever run at. Remember I said.I needed an alignment after the one when the car was stock the toe was way off steering off center?
Have you talked to any of your autos guys who run koni.there and in winter?


Winter here and pavement was horrid. Not only that we had extreme cold which turns the oil in the dampers to sludge. Add on bad pavement blasts to oil that never heats up and leaky seals are very possible.

Never heard that much drama with Konis but again most people run performance mods in temperate climates.

What kind of spacers/bushings do you have for the rear dampers?

None, the rear dampers are direct replacements. The bottom of the Konis has some sort of bushing on the bottom though and that's what I greased.

My particular setup has metal guide bushings that fit into the bottom eyelet (heim joint + bearing) of the damper with washers/spacers that fit between the bushings and the inner walls of the LCA. The setup is all metal-on-metal, as opposed to stock which has "soft" rubber in contact with the inner walls of the LCA. So, the replacements would seem to be a good candidate for making noise, but everything is tightened up enough that movement should be isolated to the bearing. We'll see.

Thanks.

Just in case it was missed - you are installing those air discs that sandwich between the shock body and the bumpstop, correct? That's the only other thing I can think of that might cause repeated issues like this.
