go with Sol's brake upgrade at board sponsor perfectpower.com. With all due respect to the great opinions thus far, no better bang for the buck than the larger floating rotor (less weight than stock and larger cross drills), they fit in all 18" wheels, same calipers and new pads (your choice). add the larger snap on stock ducts and BANG. Trust me.

 

BCS996TT,
You need to answer a fundamental question before making any sort of decision regarding brakes...what do you want out of the system?
If you are looking strictly for performance, than I would argue that our StopTech front 355mm BBK is the best bang for the buck option on the market. It is the same setup that the car that won the One Lap of America this year had on it: http://www.stoptech.com/press_releas...pofamerica.htm It has substantially more heat capacity than the stock setup.
The bigger rotors are a superior heat sink, which is key for a BBK. One of the biggest advantages is that our rotors flow more air than anything else on the market. We have patented vane technology that draws significantly more air through and out of the rotor. You can see what the vanes look like here: http://www.stoptech.com/faq/data/faq16.html Metallurgy is important as well, and plays a role in how much heat the rotors can take before they crack, etc.

ColorChange is correct on this point...the Big Red's have 36-44 piston bores. Our kit has smaller pistons in the front in order to maintain proper front and rear balance. Not only will it maintain proper bias, but as a byproduct, you will have a firm pedal with less travel because less fluid is displaced to move the pistons.

If you want aesthetics, then maybe an expensive 8 piston system is the way to go. You don't need to spend an arm and a leg to have superior performance however! We continue to prove this point each day. In fact, Bill Auberlin's BMW 3 series clinched the World Challenge Touring Car championship running our brakes this weekend at Laguna Seca, and the Tripoint Mazda won the Touring race using our brakes while setting a race lap record: http://world-challenge.com/news/04press163.html

The parts on those race cars are identical to the parts in this kit. We only make one line of brakes...our race brakes are our street brakes...literally no differences whatsoever. Those cars were running smaller rotors than the Porsche kit (and the piston bores in the calipers would obviously be different)...that's it! The best part is that you can run these full out race parts on the streets with no ill-effects, and then take them to the track on the weekend and wail on them until your heart's content.

ps your car looks killer with the black rims with polished lips.
