itll be fine.
2yr replacement warranty is what makes it very tempting:)
i do heaps of daily driving, track work and winding roads with no probs. 20kkms a year worth. keep in mind race tracks are alot smoother than your suburban roads too.
if you are to go budget coilovers my recommendation is g4.
you can chose your springrate, dampers (street/track/drift) but if you car is still a daily driver go street spec damper.
imho they are underrated.
blaze into a corner, hit a road gap and the suspension just laps it up.
if you are going to do trackwork you will definately appreciate coilovers.
my cars been through heaps of suspension setups and only coilovers has enabled me to push my car harder than before.
i dont even bother with 2nd hand shocks and coilovers unless i know their history and its mega cheap.
