Having a drilled or slotted setup does nothing to improve braking performance except potentially reduce fading and heat. When I say performance, it can mean many things though. Bigger pistons, more pistons, larger rotors could mean more brake torque. Tire compound, tire sizes/widths are things that also help in brake performance… since that’s what is in contact with the road.
Long ago when braking technology was very primitive and gases were produced during braking due to the nature of the pad technology, the slots and drilled holes served as escape routes to cool off the brakes. Now a days its mostly a look thing. Pad technology is leaps beyond than what it was when that was first introduced.
Having a slotted/drilled setup may only help in increasing cooling but nothing else. Under some circumstances and with certain poor quality rotors, they may crack as well as the rigidity of the rotor is compromised when it is drilled/slotted all over.
Less pad/rotor contact surface means less stopping power.
I only run a rear powerslot slotted rotor, fronts are blanks.
I consider S13 stock rotors and calipers dangerous to be honest. I honestly thought something was wrong with my entire brake setup when I first got the car, only to realize all 240s suck stock in ever so many ways, especially the brakes. It freaked me out how much the brakes sucked.
When I first got the Z setup on, I was expecting astronomical change in braking performance, like some ferrari or some dumb shit like that lol, because it was going from 1 piston to 4 piston, larger rotors albeit slightly, etc… but the truth is the Z setup feels to me what the car should feel like and come like STOCK… that is all. It is nice and totally rocks over the stock garbage just doesn’t feel exceptional or to put it simply, what I want.
I am thinking 6 piston lightweight willwood calipers and aluminum hat rotors/etc… actually… But I’m not 100% yet. The rotors are 13. something inch and the thickness is like 35mm which is the thickest rotors I know of. So basically that will be no brake fade from like a zillion tripple digit stops over and over again. In other words no brake fade > perfect.
If you stop from 160-200km/hr more than a few times even with Z brakes you will have mad fade… of course not everyone does that.
Also to be honest, I do not believe in the “thats too much” when it comes to brakes or… “even with my super powerful motor I do not use anything more than Z brakes”.
You can never have enough braking power, less fade, etc… Brakes are a beatiful and functional thing heh.
Where do you get EBC stuff? If I’m not upgrading/selling my current setup yet, I will want to purchase some EBC red stuff pads. I ask the guy who is in BC running PDM-racing, he told me he no longer does business with them since the last 6 years (I guess they had a little fist fight and kicking business-wise in the past).
