Fortune auto 510 vs 500

[project925]

I'm new to this and I don't know much about coilovers. But my goal is to get my car ready for the track asap! Iv been looking into coilovers and I have my mind set on fortune auto coilovers. But Im no sure if I want the 510 series or the 500 series. The only difference I see is the price.

can any one tell me the difference between the two and if the 510 series are worth the $400 difference?

my s13 is my daily driver but i'm not to worried about comfort. I just want coilovers that preform well on the track.

There's already a thread dedicated to the review of these coilovers. Search.

For performance on the track, get 510s. Just don't complain a few months down the road that they're harsh on the street.
