I'm upgrading my brake pads to HP+ and wanted to know which rotor would be best OEM, or something cryo treated. I know they will have to be blanks but I had read on the racing brake site that when you upgrade to racing pads, you must make sure the rotor was hard enough, or the pad would just glaze the rotor over and braking performance would decrease.

What do you guys recommend?

Car has Ohlins, Gendron FSB, Mugen Exhaust, OEM AP2v1 w/ 245/275 A6

 

I run the HPS+ (are they similar to the HP+?) on my OEM rotors for street duty. Sometimes I beat on the car pretty hard when DD'ing it, although not nearly like you would for any track/autox event. That being said so far they have been a great pad and I have noticed no long term or short term effects when banging around town.

 

Don't you have to stay stock, not cryo treated to be legal?

 

Honestly, I would not put any money into rotors for autocross. Stick to whatever is cheapest.

 

top S2000 rotors are Rockauto, Autozone, Centric, NAPA, and so on.

 

HP+'s aren't racing pads either

 

Get the cheapest rotors you can lay hands on, and redirect the savings to your tire budget.

Why are you even changing rotors, for that matter? No need to change rotors with pads unless your old ones are dead (heavily cracked or worn down to minimum thickness).

 

I run stock rotors with stock pads, same pads/rotors for 2 years of racing and daily driving. You don't need anything more than stock brakes to win (even at the national level) in stock class autoX. The s2000 pads are pretty awesome IMO (though some will disagree.) You only brake hard at the MOST twice in 1 run, most courses don't require much braking at all and it's typically only for a brief period of time. I agree with above, run the stock stuff and save your money for Hoosier A6's.

 

I'm assuming AP1 pads since you have an AP1.

To the OP, I would try AP1 pads, they give a bit more initial bite than the AP2 pads and they also dust less so it's a win win

I was not a fan at all of the HP+'s although they did provide a bit more initial bite than the AP1's everything else failed in comparison.
I've also never heard anything good about cryo'd rotors, I use centrics and have been happy.
