I beg your pardon?

I believe he's referring to the fact that increasing the front braking power, without also increasing the rear, will change the brake bias ratio toward the front. Luckily, it's probably a small shift, in the benign direction of front-heavy bias.

Very well. Kindly thank you for the clarification.

Very nice, parts look great, and GT3 ducts can't hurt, either.

So where's that RSS sticker going? Wind deflector?

Update
November 18, 2011 - Location: German Performance Options
Vehicle - 2003 Porsche Boxster S
Parts - GiroDisc 340mm Two Piece Floating Rotorm, 997 GT3 Brake Duct Spoilers, GiroDisc Stainless Steel Brake Lines, + factory OEM brake pads.

As the title states, I pulled the trigger on a front set of GiroDisc rotors for my '03 S. Scaling in at 340mm (10mm shy of the 996 GT3) versus the factory 317 OEM rotors. They are larger and lighter, advantageous. In correspondence with the rotors, I opted for stainless steel brake lines + 997 GT3 brake duct spoilers as well. The installation occurred this past Friday at my local shop, German Performance Options in Nashville, TN. For the better part of 3 years, they have squared me away from general maintenance intervals to my KW V3's + AASCO LWFW. In sum, top notch. Good work, solid work. Onto the installation.

317mm OEM Cross Drilled Rotors (L) + 340mm GiroDisc Cross Drilled/Slotted Rotors (R)


317mm OEM Cross Drilled Rotors (L) + 340mm GiroDisc Cross Drilled/Slotted Rotors (R)


317mm OEM Cross Drilled Rotors (L) + 340mm GiroDisc Cross Drilled/Slotted Rotors (R)


Progress.





Success!

Did you ever end up weighing them vs. the stock rotors?
