lunytnz Need new rotors: slotted?

I'm due to replace the front brake pads on my 87 and I'm pretty sure the rotors are going to need to be replaced, too (according to my maintenance records, I turned the rotors the last time I did the front brakes).

If I'm going to order new rotors, I'm thinking I might as well get slotted discs. Or, is it not worth it unless I'm out at the track? (which I haven't done in years)

If you agree, is there an obvious best choice for rotors? (I have Hawk pads)

First thing I'd do is see what type of rotors your pad manufacturer recommends for the type of pad you plan to use.

This is all based on reading so take it with a grain of salt.
Drilled and slotted will remove brake dust and dissipate heat better. The down side is they can be prone to cracking around the holes. This would be more towards a tracked vehicle.
Second is slotted. Dissipates dust better but not the heat like the above. More inclined towards someone that drives aggressively.
Last is your normal solid rotor for standard driving.
Slots and/or drilling will wear softer pads quicker than straight rotors.

I have ceramic pads on all 4 corners of mine, drilled & slotted rotors on the front and slotted on the back. It takes a little time to warm them up so they really grip. Why do I have this setup - because that's how I bought the car and haven't had a need to replace them yet. I don't track my car but I do love those country roads with curves and these do pull the speed down right now.

Sorry - that's all I can say on the subject. Hopefully someone more knowledgable will add to this.

Realistically you'll be fine with any. Input drilled and slotted powerstop from rock auto on mine. Look good, stop well.
