Whiteline gear is good for street applications and the odd monthly track use

But if you're a hardcore track user or have a fair bit of power, then i would recommend the cusco gear. I've had both gears on the car and cusco is great but for the $ you pay for the whiteline gear, its not a bad deal.

Horses for courses

p.s. you should watch what stace does on the track (or out of it) to see how easily he can put stress on his white (line) bits!
