this is atleast the 50th time ive heard this. this is absolutely not true.
What a 'good' ride is is highly subjective. I have heard plently of people say how 'great' a coilover rides and then when I ride with them it's back breaking. I have owned several different coilovers on my cars over the years and have come to the conclusion cheap coilovers are not worth the money. Nice coilovers (atleast seperate adjustment for compression and rebound) work well on the street but are overkill unless you track your car.
