Just to confirm do the OTS Koni yellows have height adjustable perches & can the rears be adjusted w/o removal? Also, what increments do they allow you to place the spring (ideally @ .25" would be ideal since I'm looking to keep my car @ stock height or lower @ .25"-.40" at the most)?

 

Yes there is a threaded collar that is compatible with the front Koni SAs. Since it is a threaded collar on both the front and rear (rear is on the spring bucket) your range of adjustability is infinite withing the max and min settings.

There is also the snap ring that you can set in two places on the front damper which will determine where the threaded collar rests on the damper body.

 

I just installed these on mine. Right now I have 500lb x 2.5 ID x 8 inch springs upfront. My ride height is currently about 1/4-1/2 an inch higher than stock at the lowest settings. I have a set of 7 inch springs on the way that will hopefully fix that. IF that doesn't work I am going to get aftermarket top mounts as well. For the rear I have 8 inch x400lb 2.5 ID springs that I am using with bc racing upper and lower spring perches. Still dialing it in, but it feels awesome so far
