Default 2003 wrx slotted rotors OR H-6 blanks

Right now, I have drilled and slotted rotors on my 2003 wrx (prev owner installed). I am debating either just upgrading to slotted rotors OR blank H-6 rotors. The slotted 2003 rotors will also be vented, the blanks for the H-6 upgrade are not, but the diameter of the rotor is bigger. Opinions or personal experiences in which I should choose? Thanks.

Unless you are using incredibly ****ty brake pads, there is no need for drilled or slotted rotors. There is no problem with non-vented rear rotors, unless you're tracking the car a lot.

You talking front or rear?

You can't have vented rears on one option and non vented as an option.

For the rears assuming single pot calipers, h6 all the way.
For two pots, doesn't really damn matter

the 02-03, 04-05 used two different styles of floating calipers. Both of those used a solid rear rotor. As narrow/thin as that rear rotor is, I wouldn't trust a vented rotor (if one exists) for that application.

the 06-07 (and earlier JDM cars) had a 4-pot front, 2-pot rear fixed caliper. The Fixed 2 pot rear caliper used a vented rotor.

You will need to determine what you have before you order rotors.

I have an 03 with single pot rears. The H-6 upgrade uses a caliper bracket from an 00+ outback/legacy allowing for a wider caliper.

the bracket moves the caliper out allowing you to use the slightly larger h6 rotor. you still use your factory caliper.

Yeah no, the vented rotors are 18mm thick, non vented are 10. You need different calipers and brackets to use the wider vented rotors.

The 1st gen legacy turbo had a small (266mm, wrx sized) vented rear rotor, but those calipers and brackets are hard to track down and use a funny pad shape.

The 290mm "H6" sized rear rotor does come in a vented version that goes with the 2-pot rear calipers, and also the 05-09 legacy gt. You can bolt the lgt brackets and calipers on and use the wider, vented rotors.

Oh okay. Thanks everyone for the feedback I was under the impression I could get the 290x10 vented.
