i just dont see the point in forking out the cost for good coilovers when the car has no real need for them. horses for courses really. If someone feels they need them then go for it, im just saying imo its a bit of a waste in money.
I'll add another note that good suspension doesn't have to be use on Track only.
Actually, good suspension "Work" the most on uneven, bumpy, back road that most people drive on everyday.
As track surfaces are all pretty "flat", you can get away with a lot more.
So designing a track suspension does not require the range of movement that a back road fill with bumps and holes would require.
For me personally, it is not how fast you can go around the track... but how enjoyable it is to drive the car.
If you want the car low and it is your style, I have no complains on that.
My role as a suspension designer is to make something that will fit your need AND do its job as well as possible.
Going low doesn't mean the ride have to be rubbish (well, up to a point), and having and adjustable coil overs that can work well on track doesn't mean you have to suffer a horrible ride 95% of the time when you drive on the road.
You CAN drive the car, enjoy the drive everyday, and enjoy the occasional track day if the suspension are specified properly.
That to me is actually more difficult to do than to release some ultra stiff suspension that are unusable on the road but it will take off half of a second a lap in a car that was driven by a pro racing driver.
