Girodisc D1-220 Replacement Rotor Rings (400mm) Girodisc replacement rotor rings are direct replacements for the iron discs on your Girodisc A1-220 400mm two-piece rotors, with no modifications necessary. New cap screws and washers are included with these replacement rotors. We do not recommend re-using the old hardware. (This kit is contains two cast-iron discs and associated hardware. No aluminum center hat.) The replacement rotor rings and hat mount together through a floating mount system which utilizes 8-10 high strength alloy steel drive pins manufactured by Girodisc in the USA and are cadmium plated for corrosion resistance. The alloy drive pins transfer the load from braking while maintaining the axial and radial float between the disc rotor and hat. The pins are secured by grade 12 cap screws with hardened washers and mounted with anti-noise spring washers to allow for heat expansion while eliminating the rattle and noise associated with floating rotors. Rotor ring-only replacement helps to minimize costs and deliver outstanding performance. Sold/priced per pair.

IPD Competition Intake Plenum for Porsche 991.2 TT/TTS FITS: Porsche 991.2 Turbo/Turbo S (2017+) The 991.2 Turbos don't substantially benefit from any one particular upgrade, but the sum of IPD's improvements in the intake tract deliver a superior overall 991.2 Turbo/Turbo S compared to the already impressive stock car. Porsche made a number of substantial upgrades to the 991.2 Turbo engine, including revised intake ports, larger injectors, a higher-volume fuel pump, larger turbo compressor wheels and more efficient intercoolers. But the factory intake system remained relatively unchanged from the 991.1, giving IPD a window of opportunity to upgrade and improve it. The IPD 991.2 Turbo Competition Plenum delivers excellent engine power and torque gains that raise the performance of the already potent supercar (as well as the hair on the back of your neck). Horsepower gains are made throughout the power band, with the bulk being realized between 3500-5000 RPM. Max gain of 45 wheel horsepower come at 4300 RPM and hold strong all the way to redline. Torque is even more impressive at 60 lbs-ft. in the midrange with a massive torque gains from 3500-5000 RPM. When combined with the IPD 991.2 Turbo Y-Pipe, available in the drop-down above, gains jump to 70 lbs-ft. of torque and 50 wheel horsepower!

IPD Intake Plenum for Porsche 991 Carrera 3.4L FITS: Porsche 911 Carrera (2011-2015) The 991 Carrera is arguably one of the sexiest Porsches to come out of Stuttgart. But like most Carreras, power output is controlled to meet a performance target below the Carrera S, one that satisfies the masses but not necessarily the dedicated Porsche driving enthusiast. IPD helps scratch the proverbial performance itch for Porsche drivers looking to elevate the already visceral driving experience to the next level. The 3.4L engine in the 991 is relatively unchanged from the previous 997.2 Carrera. It continues to employ the 82mm throttle body just like the Carrera before it. IPD's new specifically-designed 3.4L DFI Carrera intake plenum is a direct bolt-on upgrade that replaces the factory air distributor and utilizes all pre-existing factory hardware including the OE factory throttle body. INCREASED POWER & TORQUE ACROSS THE REV RANGE The improved IPD intake design creates increased air velocity and air speed resulting in impressive power and torque gains of 15 HP and 14 lbs-ft. at the wheels on an otherwise-stock 991. As with most IPD plenums, the bulk of the power gains are realized in the mid-range where they are most used and enjoyed. Unlike other mods, though, the IPD Plenum delivers net power gains across the entire rev range. Installation time is four to five hours and should only be performed by a qualified Porsche technician. Feel free to give us a call at (844) 438-7244 with any questions!

IPD Intake Plenum for Porsche 997.1 Turbo Designed for the 74mm throttle body to maximize performance and durability! FITS: Porsche Carrera Turbo (2007-2009) In 2007, the incredible 997 Porsche Turbo was the most revolutionary and capable Porsche Turbo to ever come out of Germany. This already-explosive power can be further increased with the 997.1 Turbo IPD Intake Plenum. The patented IPD Plenum design unlocks power and torque increases over factory power curves from launch to redline. Maximum power increases take place in the midrange where they're most needed and most critical. The 997 Turbo ECU requires an adaptation period through either a series of hard pulls on the dyno or 10 to 50 miles of hard driving (on a closed-circuit or race track). Turbo customers looking to increase engine power and torque without pushing the motorsport envelope to redline would best benefit from the 74mm IPD Turbo Plenum. This version of the plenum uses the factory 74mm throttle body and delivers impressive performance gains for both stock and slightly modified Turbos with exhaust and software. To push beyond these performance mods, we recommend upgrading to the larger IPD Intake Plenum for 82mm Throttle Body . Add IPD's extraordinary high-flowing 997.1 Turbo Y-Pipe for even more dramatic increases in horsepower and torque. This IPD Plenum and Y-Pipe are designed to work perfectly together. We recommend installation of this IPD Plenum be performed by a qualified and trained Porsche technician.

FITS: CHEVROLET CORVETTE C6 WITH Z51 PACKAGE (2005-2013) Thunderhill is an Authorized dealer for GiroDisc products and we are one of the largest stocking dealers in the country. We ship most products same or next business day to ensure we meet your delivery deadline. The GiroDisc system is an upgrade to a 2-piece steel rotor and aluminum hat combination and is a direct replacement for the OEM brake disc. The 2-piece floating disc will bolt directly to the car and work with OEM calipers perfectly. By upgrading your brakes with these lightweight high-performance replacements as opposed to a big brake kit, your factory bias is maintained as well as your ABS efficiency. The Giro Disc rotors are lighter than OEM pieces. The reduction in rotational and unsprung weight allows for quicker acceleration and suspension response. When used with Pagid or PFC performance brake pads, and Thunderhill RF-1 brake fluid (also available from CompetitionMotorsport.com), you have an amazing solution to overheating, cracking and warping rotors. The central hat section of the disc is made from 6061-T6 aircraft specification aluminum. The disc is manufactured from cast iron which is constructed in the USA and is made to the same specification with the same material used by professional racing organizations. The rotors curved vane design was developed in racing and acts as a centrifugal pump to force cooling air through the disc. The rotor and hat mount together through a floating mount system which utilizes 8-10 high strength alloy steel drive pins manufactured by GiroDisc in the USA to our own specifications and are cadmium plated for corrosion resistance. The alloy drive pins transfer the load from the brake action while maintaining the axial and radial float between the disc rotor and hat.
