I was recommending only the slotted rotors, not the drilled + slotted. ECS offers both with a marginal price difference.

Main benefit of the slotted is to allow the gas to escape when braking.

 

def. slotted only the drilled is more for looks and from talking to the hard core track people they have also said drilled will crack under alot of pressure i am running my next track weekend feb. 21-22 i am going to keep the brakes as is because the pads are pretty new still but after that i will need rotors and pads so i will upgrade them as needed as far as exhaust goes i have strieght pipes after cat (loud) im not too worried about the hp stuff there's not alot out there but 340 is enough right now when i start to take some weight off the car it will feel like enough for a while by the way i got bilstein pss9's today and rear sway bar anyone know how hard the install is ?

 

if youve got the money buy the Supercharger

 

Here is a light weight option less then the ECS rotors

you can get a shifter and If you are racing get the upgraded mounts. Other people seem to say they really help
