Girodisc
MP-1082-2 Girodisc Magic Pads (Rear)
$95.00
GiroDisc "Magic Pads" are the solution to your squeaky, dusty, expensive factory replacement pads. They have lower dust than typical factory pads and much less than other performance pads. You won't be cleaning your wheels nearly as often!
Additionally, they have great initial bite, something most less-expensive pads lack. But the real reason people like Magic Pads so much is they are the "silver bullet" to brake noise problems. Magic Pads are a semi-metallic composition that is easy on rotors and on your wallet.
We recommend always replacing pads as a whole car set when switching compounds. All Magic Pads come with anti-noise shields pre-installed and included in the price.

SPEEDCOM SCC-SEIH SINGLE EAR HEADSET DETAILS
Manufacturer: Speedcom
Manufacturer part no: SCC-SEIH
Flex boom length (including mic): 18cm (7.1 in.)
Cable length: 1.1m (3 ft. 9 in.)
Cable connector: IMSA 4C, male
COMPACT AND COMFORTABLE EARPIECE
The actual speaker portion of the Speedcom SCC-SEIH Single Ear Intercom Headset is quite small. Measuring approximately 3.5cm in diameter and 2.0cm thick including the pillow pad. This pad compresses easily with the right amount of give for comfort.
FLEX BOOM MICROPHONE
Attached to the speaker is a flex boom noise cancelling microphone. The flexible portion of the boom is 14cm long and the mini microphone adds 4cm, making it 18cm (7.1 in.) long in total to easily reach the user's mouth. The compact size works in every helmet we've tried it in.
ROBUST WIRING MEANS LONGEVITY AND RELIABILITY
Why do students pull the earpiece out by the wire? That's a question for the ages, perhaps. Recognizing this, Speedcom changed how headsets are built by making the SCC-2MPI with a built-in molded plug. Other brands use the two plastic earpiece halves to hold the cable, but Speedcom uses cabling that has a security block built in during the manufacturing stage, so you can pull on it all you want.
Is this a more expensive way to build a headset? Yes. Is it the better way to build a headset? Also yes. Using the popular IMSA wiring protocol, the cable is 1.1m (3 ft. 9 in.) long, easily reaching a communication unit that's dash-mounted unit, shoved next to the seat of a D.E. car, or in the instructor's hand.

Girodisc Titanium Brake Pad Shields
FITS: Porsche 991, 992, GT4 Rear
The problem of brake fluid boiling is due to heat transferring from the rotors and pads directly into the fluid through the caliper pistons. When brake fluid boils, it releases air that is normally part of the molecular structure of the fluid. This air is compressible, of course, and the brake pedal goes to the floor instead of moving the caliper pistons. Production cars tend to suffer from this on track days because they don't have the extensive cooling ducts and exotic brake materials found on race cars.
Race-only brake calipers generally come with titanium caliper pistons for one reason: titanium has low thermal conductivity. This means it's very bad at transferring heat, which is good if you're trying to keep your brake fluid from boiling. Here's a comparison of materials and their relative thermal conductivity ratings (lower is better):
Titanium 6AL-4V = 6.7 W/mk
Steel = 52 W/mk
Aluminum = 130 W/mk
Most fixed calipers use aluminum pistons which are, unfortunately, excellent at transferring braking heat to your brake fluid. Our solution is to place Girodisc's thin titanium shims between the brake pad and the caliper pistons. This helps prevent braking heat from transferring into the pistons and, thus, into the fluid.
For cars that are going to see hard or multiple track days, these shims are affordable protection from losing your brake pedal at the wrong time and making your track day very expensive.
Water jet cut to exact size; no cutting, grinding, or swearing involved.
Price is per axle (four shims)
