Koni Sport Springs and rear shocks.

[BlackbirdM3]

Koni Sport Springs for sale, front and rear set.
Part # Front: 2220-1048
Part# Rear: 2220-1049

I don't know much about these. I'm told they are about like a set of H&R Sport Springs. They lower an M3 20-25mm. They were way too soft for my use, I upgraded to a set of H&R Race springs. They came on my car, I have no idea how many miles are on them, my guess is not that many since the previous owner never drove the car. $200 obo.

I've also got a set of Koni Sport rear shocks with upper mounts. No idea how many miles are on them. I upgraded to TC-Klein externally adjustable ones with mono-ball mounts. $150 obo.

$300 for springs and rear shocks? I'm open to offers, shoot me a PM and we can go from there. I need these to go away so I can get some new bushings for the back of the car.

Shipping will be about $20 or so for the springs.

Morning bump. I'm a motivated seller, please make me an offer.

Price reduced, how about $175 plus shipping? I need these to go away, but I won't give them away. Make me an offer I cant refuse.

Thanks for looking,

I'm thinking about this, just can't find anything on the spring rate. If I could figure this out, it would be perfect since I'd be running them on an M3.

I have spent days looking for spring rates on these, but the best I could do is having other people tell me they are about the same as a set of H&R Sport springs. They are not a firm ride, but I would suggest running a set of Bilstein sports with them. I had BS on the front of the car and the set of Koni shocks I just sold on the rear and the ride was nice, but when I tried to autoX the car it didn't work well at all on tight corners, it pushed like a wheel barrow. The pics I included of my car were shot with the springs and bilsteins on it. I think they really do need the higher initial compression damping the Bilsteins offer rather than what the Koni's can provide.

You can try and calculate the spring rate, the wire dia is 12.64mm for the fronts and 14.21mm for the rear. The dia of the rear springs is 13.5 cm and the fronts are 14cm on the nose. I can say they are less firm than the H&R Race springs I have on the car now.

Any takers?

You wouldn't happen to have the compressed and decompressed length, would you?

This calculator is asking for it:

The free length of the fronts is 9 7/8" and 7.5 for the rears. I don't have any way of safely compressing them. I'd guess the compressed fronts would be about 5/8s of the free length. The rears perhaps somewhere between 5/8 and 2/3 free length.

With my TC Klein shocks and struts set full hard, the car was the most predictable car ever. Left/right transitions were perfect. The trouble I had with them was when pushed hard into a corner autoXing, I'd bottom the outside front struts. The struts flat out didn't have enough travel to keep from bottoming. Even though the springs were made by Koni, I think the higher intial compression damping of the Bilstieins would mate better with the soft initial compression of the springs. I didn't have the bottoming issue when I first got the car. It understeered horribly but didn't bottom. I suppose the cheaper fix for the problem might have been to just get a matching set of Bilstein Sport rear shocks back when I did the upgrade. Now with the H&Rs, I think I might have undone the predictability I had. Either that, or the soft springs were masking the worn bushings in the rear of the car (hence the reason I'm selling the springs to pay for all the related stuff that needs to be replaced while I'm in there.)
