My R4-S Porterfields on my Legacy Spec.b served me fine even on the few track days I did with her.

For those looking to grab drilled/ slotted.... they do not provide better braking under most conditions. They do wear out pads faster, are noisier (cricketish sounds

) and will help with cooling but remember.... brakes are a friction based tool. The more surface area the better the braking. Unless you really heat them up and thus need the drilled/ slotted for hot air venting.

Also if you are in a cold wet climate slots can actually hold water and can give you a moment of weak braking. Most noticeable for me was always right after a car wash. Driving out of the end the brakes needed two pumps.
