:auto:
whats up G2 fam, im pretty new the game and still trying out some things…

well check it out. here the problem, Ive been looking in to suspension setups and springs rate. but have came between 2 setups. keep in mind i’m basing my setup on track use mainly so here it is!

this is the battle between the 2!

progressive coilovers series 2! rate(350/250)
(been reading good reviews,and very affordable)

then there is what most guy on the track would perfer.

koniyellows w/ gc! rate (380/250)
(best choice thus far, yet very pricey)

spring rates are nearly the same! so thats why ive came between the two.

any help from you track dudes!
