Don't know if this would help but from what people tell me and my experience with ksport's the rears don't go as low as far as sleeve adjustment and not messing with the pre load. Here is how my ksport's looked on my wagon, 2500lbs +/- a few >>
Car: Honda Civic Wagon RT4wd
Wheel size: 15x8 0 offset
Tire size: 165/50r15
Before:
Brand: Ksport CHD010-KP Kontrol Pro Damper System (F)9.8/549kg/lbs (R)5/280kg/lbs
Front and rear slightly tucked
Front: i still got an inch lower on the sleeves, pre load not touched.
Rear: bottomed out on the sleeves, pre load not touched.
Camber: (F) -3.8 (R) -4.0
Suspension setting: I'm on the highest setting.
After:
Brand: Ksport CHD010-KP Kontrol Pro Damper System (F)12kg replacement spring from ksport (R)9.8/549kg/lbs
Front tucked and rear got a inch gap due to the stiffer spring.
Front: i still got 3/4 of an inch +/- lower on the sleeves, pre load not touched.
Rear: bottomed out on the sleeves, pre load not touched.
Camber: (F) -2.5 (R) -2.0
Suspension setting: I'm on the highest setting.
I moved my 9.8kg springs to the rear and got some 12k replacement springs for the front and as you can see since i got a higher spring rate on the rear they don't go as low as with the 5kg that i had which makes sense if i'm bottomed out already and add a stiffer spring which isn't going to compress as much ending with a higher stance but better suspension feel.
