Re: ksport coilovers
The reason they're shit is because they have shitty valving. That is why the ride quality is so bad. Stiffer springs will make a car ride harsher and stiffer, stiffer springs on crappily valved shocks makes a car ride like a nightmare.
That being said, I would buy Megans/K-Sports/D2s/etc before I ever bought tanabes, GAB, tien, or PBM as they all use the same shitty quality struts that Megan/K-Sport and the others mentioned above. It's a proven fact, the Japanese don't make good shocks, they go to the germans for that, which is why Mine's puts Ohlins and Bilstiens on their cars.
