I've been through a few suspension and wheel setups at this point (bilstein coilovers and mountune springs on OEM dampers) but one thing that has stayed consistent was a certain buzziness transferred through the car. The damping for the large bumps varied quite a bit through these setups but it feels like the car transmits all the small road imperfections up through the steering wheel and interior. Have you noticed any difference with the Konis along these lines?
Good question. Again, I would definitely say these Koni orange struts behave much like you would expect a "stock sporty" suspension to be. Meaning very OEM (or better than) with very good supression of NVH effects. Honestly the car is quieter and smoother without being the least bit harsh.
In full disclosure I must report that today while taking a very extreme righthand corner (downhill, negative camber) it loaded up the front left strut enough to hit the bump-stop and make an odd rubbing noise for only an instant. I was able to see some black tire scrub mark-off on the wide base flange (integral to the strut) that is the spring footing. I believe the interior sidewall of the stock tire rubbed momentarily. Again, this was a rather unique street corner going downhill and leaning outward which put maximum compression on the outside front corner. And I was taking it at near limits of adhesion
Two possible fixes came to mind: Looking through the rim spokes it seems there is enough "meat" on the spring base plate to be rolled (gently hammered) which would increase the clearance gap. Alternatively I thought about using 10-15mm wheel spacers up from to open the gap. Worth mentioning that the Koni front strut spring bases already come with nicely rolled/radiused edges so there was no risk of tire slash. It was a contact that left a rub-mark on the orange strut about the size of a dime.
Before you freak-out that this means a significant clearance mismatch, I can report that for the rest of today I looked for ways to replicate the incident to no avail. I zig-zagged hard at good speed and nothing. I steered into manhole covers and potholes to jarr hard enough to be a concern but again nothing. So in 99% of driving conditions can safely say it it interference-free.
For how well the car rides now, how it has gained comfort and rid the OEM harshness, I wouldn't hesitate a moment to put this setup on. And of course, its staying on!
