Yes, stock sport springs on 2013 128i. Wish I understood how to create the footer with modifications that have been installed though. Lots of suspension upgrades - M3 front and rear pieces; ECS sway bars (squeak wildly), etc.


Interestingly, the left upper strut mount was full of dirt/mud and on its way out - with 38k miles. Not sure why it was so grunged up?

The Flatter in the corners feel comes from rebound dampening as well. If your old shocks were worn out & not good at rebound dampening OR if the Koni Special Actives have stiffer rebound dampening than stock they will move up slower, in effect holding down body roll.

When I changed from stock to my new shocks it was a massive improvement in cornering "flatter" feel.

Only had 39k miles, no track time, on the suspension prior to going to the Special Actives. After ditching the Run Flat tires, the suspension seemed to be too soft/mushy for the performance all-season tires in 17" diameter.

I replaced mine when I installed my new springs and shocks etc. at 50K the old bearings made a lot of crunchy noises. I think I picked up new ones for around 20 or 30 bucks a piece. I bet the mushy feel is from the stock springs.

Springs remain as the OE sport suspension pieces. I just think the 'mushiness' has to do with being set up for the run flat tires where the suspension has to provide all of the damping/cushioning. Without run flats, there are other parts that can now be recalibrated for performance without the sacrifice of ride comfort.

I think I made the right decision for my needs as a DD. Still want to consider RTABs at some point, but again for street use, maybe not necessary. Need some more time with things!

MAMSport - now that you have some miles on your Koni shocks what do you think? Still a good choice. At 70K on my 128i with sport suspension I'm looking at new shocks.
