That's an incredibly low price Malacoda! When did you purchase your set?
I have just put a few hundred miles on my car now, and can respond to how they handle/operate.
Seconding exactly what Natedog wrote in post number one, they are set to the middle setting front and back, book says they adjust differently front and rear, but I get level action as the car hits/absorbs/rebounds over large bumps. Still get passengers who get air time in the front seat when dipping and rebounding through very deep/tall and long road "imperfections", much like half height bus speed bumps. Not an issue with the suspension just the way a small light weight car handles stiffer coils I assume. Much more controlled than any drop spring and Gr2/ExcelG combo I have tried. Super bumpy roads will give you lots of feedback in the car at the middle setting, and I can't see that changing much as the suspension "loosens/works in", but the feeling of control from the stiffer springs and reduced oscillation/control of the springs, is really eye opening. I have yet to experience the tires dancing sideways when loaded to the side in corners and experiencing a bump or two. This bodes well got these coilovers. I am running Galant/Eagle wagon wheels, with 205/50 R15 Dunlop Direzza DZ102 tires. Tires were produced Dot code 4114, so other than sitting on the car for a year waiting, they are brand new and handled the Gatineau hills very well the other night. Short of Calabogie Raceway, the Gatineau Hills are the only local spot with lots of nearly blind twists and turns (lots of grassy shoulder), and the chance to avoid raccoons as most people go up at night to "see the stars and the city from elevation".
I give the K Sport Kontrol Pro an initial review rating of "great product for the price".
I have my trunk roofline adjusted near to stock height, with the front wheel well ago showing larger than the rear, as it should given body lines, and the car handles so much better. Also my rear over axle exhaust section no longer hits the solid rear axle on big bumps as when the suspension used to hit the urethane bump stops. If I had a choice, so far without having had to adjust/readjust the height or lock ring tightness's, I would never have bought replacement sets of factory style replacement suspension. Go straight to these coilovers with braided stainless lines for the brakes. Also, bigger front brakes and rear discs should be priority number two after that.
