Grip/ Proffrsional Track Coilovers

[hachirokkos]

I currently have a D2 drift spec suspension system on the car, and i really need a new one one way adjustable (bound rebound together on one adjustment) .

I am really thinking of:

BC racing type ER two way, not coilover on the rear ( shock independent of spring) for 1500gbp ( bound rebound on different adjustments)





MCN-AVO triple way, for 3.500 eur ( hi speed, low speed, rebound )



Anything proffesional track use ? Trible ( hi speed, low speed and rebound ) or at least double ( bound and rebound ) to sugest ?

Has anyone tried any of the above ? Are they any good ?
