tellin you step up to the power slot rotors since your down there they work great. I have a del sol with a b18 and i have heard of people having braking problems with stock (i did) because of the extra weight of the engine but this combo solved it ....stops really quick..

 

i used ebc greenstuff. they worked great, they had a noticeable increase in stopping power on the old ef. cost was about 60 bucks. the expensive aftermarket rotors are a rip off, they don't help you stop any faster unless its a dedicated track car or they are bigger in diameter. autozone cheapies are the way to go so when you warp them its only like 10 bucks to replace them
