As per the title Has anyone used/have any knowledge of these Koni dampers?



They were on an NB. I have looked on the koni website, specifically for the MX-5 and the part numbers don't match.

Are these are the ones on eBay

Looks like it

[aka_juffa]

Yes, these are the ones on ebay.

My questions still stand.....

Give Koni a call (Top Perfomance) is the local distributor. I've had 'specials' built by them for my rally cars when the stock/sport versions didn't cut it. The numbers on these custom units didn't match anything in the catalogue. These may very well be MX5 units.

They look custom too me based on the spherical bearing set up on the bottom (and that they appear to be the same shock with differ lengths "extensions")

Ditto
Were they advertised as Konis? I can't recognise any of the parts, 'cept maybe Vogtland (spelling) springs.
the "extensions" on the right-most pair look rather dodge to me, and they would have to be extra-strong to withstand the forces associated at that part of the suspension.
Actually.... when you look at them for a bit, the damper bodies are actually rather short aren't they? rather VERY short.

Home brew.

I've never seen a Koni shock body that looked like these either. They have a Koni sticker, but they don't look like any Koni's I've ever seen.
+1 on the extensions. Super mega ultra dodgy. Definitely not the way Koni makes a shock body.
The damper bodies are rather short. Kind of like someone bought two REAR pairs of shocks and then welded together some homebrew extensions.

The extensions themselves should be ok I would have thought as the spherical bearing probably had enough movement for the angle change of the control arm with out inducing bending and they look reasonably solid. I would be more worried about their travel.

Ask the seller for the contact details of the shop the made them for him.

Appear to come from their dedicated racing line. So it solves for the dampers.

But assuming these have very little travel due to track-only purposes, and assuming very little travel = very stiff bump and rebound... the spring rates are now questionable.
Generally speaking, the stiffer the spring, the fewer the coils, so unless they are speficially made, on face-value they have too many coils to be stiff enough to match the dampers.

Ask them about the spring rates Jeff.

[aka_juffa]

From the e-bay listing the rear springs rate is 275 lbs./in and the front is 350 lbs./in. The seller states that the setup was supplied/fitted/setup by a race engineer for track use.

So who bought these?

They ended up going for $500 which is a steal! Seems like there were set up very well, and i'm pretty sure the stroke was >100mm with soft-ish spring rates.
