Koni makes great stuff, that generally works well. To do that, they have to make compromises in valving, piston/shaft diameter, fluid volume, etc...

Without knowledge of the spring specifications, vehicle weight, corner loading, etc. OK is about as good as they will ever be. That OK may far exceed the poor to OK stock configuration which often has comfort and safety as priorities over handling and performance.

If you have ridden in a car with a great suspension engineered and tuned to work together, you get to feel true performance and handling often with decent street performance.

Tein excels at building streetable and mixed street/track while RCE/KW leans more to track. Scott, Cory, Matt and myself are all good drivers, but part of what lets us be so fast in our own cars is the suspensions on them. Well engineered and setup suspensions.

You don't have to go to Scott and my Multi-thousand dollar track setups, but you can get some well engineered, good performance coils for just over $1000 or maybe under used which will likely outperform in many ways whatever you can cobble together yourself.
