"The standard pad we ship with kits is the Axxis ULT. It is a high performance street pad with good initial bite, modulation and release. It has a higher maximum operating temperature than most OE pads, but is not recommended for powerful cars to do extended lapping sessions on the track. The ST-40 caliper uses an FMSI #D372 pad shape, which was once used as original equipment on a popular performance car and is available from most brake pad manufacturers. We carry 19 different performance street and race pads for the caliper from eight different manufacturers and there are many more we don't carry."
But it's not just their track performance that makes StopTech brakes so good. It's also pedal feel and their modulated response, the linear way pedal force translates into braking force. Simply put, the StopTechs feel better than the factory system. They feel more connected and visceral.
Our buds at VF Engineering...
Our buds at VF Engineering have just finalized the software for an M3 supercharger system. Looks like those big brakes will be put to good use.
In any case, I'm pleased with Project M3. I'm becoming more comfortable with its capabilities and am ready to take it to the next level.
OK, I lied. Two months ago I mentioned Project M3 was being fitted with a supercharger. The truth is, I wussed out and cancelled the install. I feared changing the M3's character would kill it. During the 2006 SEMA show in Las Vegas, I queried every single person I met-even complete strangers-if they'd like a supercharged M3. Everyone, including the polyester jumpsuit-clad guy playing the nickel slots, said yes. And then there are guys like Aaron Neumann, guys I respect who say it's a solid idea. And even if it doesn't work out, the supercharger system (and everything else for this matter) is easily reversible. That's the beauty of bolt-on performance parts.
