you really need to do some research before you post. read up stoptech.com
Drilled rotors do not crack under normal conditions. its the people who road race and constantly heat up the brakes to the extremes of the sport. i bought some ebay drilled and slotted rotors for my car, been holding up just fine to my stopngo all city driving.
for daily driving, the rotor will not crack (assuming you buy a quality rotor in the first place.) fastbrakes.com is a legit site and dealer.
i'm sure most of you know, drilled slotted rotors, ss lines, bigger rotors generally do not help braking ability. they are mostly for cosmetics. -drilled/slotted-keeps pad cleaner and cools better, but CANNOT be resurfaced and reused after several pad changes. this is bad b/c deposits from old pads do not let the break-in compounds of the new pads to properly burn off on the rotors. so you'll end up replacing rotors every year or so. also, do not road race with drilled rotors.
-bigger rotors-increase surface area, BUT adds unsprung weight and counteracts benefit of bigger surface area.
-ss lines-more for pedal feel, if u're concerned with brake fade, get ATE blue brake fluid or Motul RBF600 Dot4.
if you really want added braking ability setup, you have 2 options.
-OEM blank rotors and better brake pads. SS lines and ATE/Motul fluid are extras. Hawk HPS and Axxis Ultimate pads are the best for daily. Axxis outperforms Hawk a bit but gets REAL dusty.
-Wilwood brake setup-bigger rotors, BUT aluminum center hat so less unsprung weight vs. weight of bigger solid rotors and even OEM rotors. 4 piston calipers, and all the benefits and cosmetics.
StopTech is the proven BEST aftermarket brake setup thats cheaper than Brembos. but at the moment, i dont think they have a kit for the Fit.
