ZHP front rotors are 325x25. ///M3 front rotors are 325x28. Guys think these would fit on ZHP with fresh pads?

Looks like you'd have to run the M3 calipers.

Yeah, if I remember correctly there's not a whole lot of wiggle room when you're puttin in the new pads. Not sure they'd clear.

Nope. You'd need a lot more than just the rotors to make that work.

What they all said.

If you want a brake upgrade...I'd look into the Porsche Carrier conversion (if you can even do it on Non-Ms)

3mm when dealing with brakes is a LOT... As I reinstalled my front brakes today, I compressed the pistons ALL the way into the caliper and after installing them loaded with the new pads, I don't think there's 3mm to spare...

Can someone explain the two-piece rotor design to me? Like why is the rotor bolted to the black part? Does it cut weight?

Not to sound like a dick, but if you read the info on the link, it explains quite a bit... The biggest thing is cutting weight. Of course, its unsprung weight, so its even more beneficial... There are other benefits too... But the biggie is unsprung weight.

I think someone on M3 forum makes good kit as well, cheaper price too.

I'd be concerned with what material that kit is made.

If it's the same/better, go for it. If not...I'd be worried with a shear becoming possible.

Ok, let me know, I'm willing to let them go for cheap since I got a really good deal on them from a dealership...

My cousin (a car genius) told me the rally road kit isn't really that good, the M3 forum kit is apparently better built. I'll try to find the link.

The guy on M3Forum who makes them is one of the most knowledgable people I've met - and *really* freaking anal about making everything is absolutely perfect. I'd trust them more than the RallyRoad brackets actually
