$879.00
Brey Krause R-1032 Harness Bar For Porsche 991 & 992 (Except Targa)
Harness Mount Bar pictured has a custom powder coat. All Brey Krause Harness Mount Bars come with a wrinkle black powder coat.
The Brey Krause Porsche 991 & 992 harness mount bar has been tested and certified by an independent lab to handle the types of forces required by the National Highway Traffic Safety Admin. DOT and SAE J385 Rev.MAR 95, Motor Vehicle Seat Belt Anchorages-Performance Requirements. The 991 harness mount bar properly locates and supports racing shoulder harnesses relative to the driver. In the case of an accident, it helps protect the driver's shoulders and spine. The harness guides also prevent excessive shifting and fatigue of the driver during the high G loads of cornering and braking. Our bars are easy to install and remove, use only existing holes and mounting points, and will not damage the car in any way.
Strength requirements for harness mounts are considerably greater than those for harness guide bars since they must support the entire load applied to the belts. A mount really can't be relied on unless it has been tested to support the loads required by the National Highway Traffic Safety Administration.
The Brey-Krause Harness Mount supported the loads specified by the National Highway Traffic Safety Admin. DOT for upper torso restraints in all automobiles. Tensile tests performed by an independent lab.

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.
This Girodisc system is an upgrade to a two-piece steel rotor and aluminum hat combination as a direct replacement for the OEM brake discs. The Girodisc floating rotors will bolt directly to your Mustang and work flawlessly with OEM calipers. 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 effectiveness and efficiency. The Girodisc rotors are lighter than OEM pieces, resuutling in a reduction in rotational and unsprung weight (4 lbs per corner) allowing for quicker acceleration, stronger braking, and faster suspension response.
When used with Pagid or PFC performance brake pads, and Thunderhill RF-1 brake fluid, you have the best possible 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 constructed in the USA, 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 ten high strength alloy steel drive pins manufactured by Girodisc in the USA to their 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. 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.
The two-piece Girodisc design allows for rotor only replacement as well to minimize future replacement costs and deliver outstanding performance and cooling.
Sold/priced per pair.

IPD
IPD Competition Plenum Porsche 997.1 Carrera-Carrera S
from $850.00
IPD Competition Plenum for Porsche 997.1 Carrera/Carrera S
The IPD "Y" design plenum replaces the factory "T" style air distributor and provides substantial power and torque gains by means of a more efficient design. Horsepower gains range from 24 to 28 depending on engine displacement and engine condition. These max power gains are experienced in the mid range where is it most useable and enjoyed.
The IPD plenum not only delivers impressive power and torque increases but also creates a more linear power and torque band. Tiptronic customers even claim considerable improvements with more positive shifting after installing the IPD Plenums.
Porsche has been controlling engine output by restricting the inlet track for decades. This has been successfully accomplished by utilizing smaller throttle bodies. This simple power control solution has been a very effective way of preventing lower level models from out performing certain flagship models, especially models with prolific racing pedigree. Although the factory engine packages are fantastic performance machines, they are engineered and developed to achieve specific performance numbers that satisfy a target demographic and compete with rival brands. Unfortunately driving enthusiasts who seek an elevated Porsche driving experience require performance levels well outside the target market.
IPD Plenums deliver substantial power and torque gains, but when combined with larger throttle bodies they perform even better. All of the IPD "Competition" Plenums utilize the next largest size throttle body offered by Porsche. In this case, the Competition Plenum does away with your original 74mm throttle body in favor of Porsche's 82mm 997 GT3 throttle body (can be added above). All of our Competition Plenums are designed to perform with cars equipped with high performance exhaust systems. The more extensive the exhaust system (headers, kats and mufflers) the better. Optimizing air intake and exhaust together creates a balanced performance package that allows the engine to inhale and exhale more air thus creating more power and torque.
IPD has pioneered another new Plenum design with the Competition Carrera Plenum. Laminar flows and volumetric efficiencies have been further enhanced with our unique and innovative internal merge collector area. This completely new approach has yielded not only great performance gains but more linear power delivery and improved throttle response as well. Gains vary depending on pre-existing mods and quality of after-market exhaust installed. As we all "should" know, horsepower and torque become harder to find and typically more expensive as we climb the proverbial performance ladder. That being said, performance components yield different power gains depending on the order they were installed. IPD tests and evaluates all products on bone stock cars, this establishes a level playing field and a better "apples to apples" comparison. The Competition Carrera Plenum however is designed to work with applications that are already moderately to heavily modified. Power gains will vary with each Carrera, but the bottom line is, there will be noticeable and impressive gains that are sure to make any Porsche Carrera driving enthusiast smile.
Power improvements will be fully realized once the factory ECU/DME makes all the necessary "adaptation" requirements. This process can be expedited with a series of "hard pulls" or spirited full throttle acceleration runs through the gears. Of course this should only be performed on a closed course circuit.
This plenum requires a Bosch 82mm throttle body, which can be added to your order above for only $225 (save $100).

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.

Arai
Arai GP-5W Helmet SA2020
$849.95
Arai Auto Racing GP-5W SA2020 Helmet
The Arai GP-5W SA2020 helmet is perfect for stock car, sedan, and rally drivers. The GP-5W is a favorite because of its tall 90mm (~3.5”) top-to-bottom eye port. The GP-5W uses its own exclusive shield with this larger opening.
The Arai GP-5W is Snell SA2020 certified with M6 washer/nuts installed at the factory. Drivers of any experience level will be able to easily install their Head and Neck Restraint system anchor posts (sold separately). The Arai Auto Racing GP-5W SA2020 also comes with the FIA-8859-2015 certification sticker found on the shell’s interior lining.
Arai Advanced Technology ScLc Helmet Shell
The Arai GP-5W Helmet is built with Arai's exclusive, very-lightweight ScLc (Super Complex Laminate Construction) shell technology. This ensures a low overall weight to offset the added weight of the helmet’s larger shield.
Innovative GP-5W Racing Helmet Shell Shape
The Arai Auto Racing GP-5W helmet SA2020 helps reduce fatigue for the driver due to its more natural head shape, smaller shell size, and lower center of gravity to assist with balance and stability.
Interior Fit of the Arai GP-5W
The Arai Auto Racing GP-5W Helmet SA2020 is designed to closely match the shape of the human head, allowing for a snug, yet comfortable, fit. Arai has developed this “natural” shape over more than 50 years of helmet design research and refinement.
Taller Eye Port for Increased On-Track Vision
Sedan drivers will appreciate the larger 90mm eye port, top to bottom. A visor peak is available for drivers not needing a shield on the The Arai Auto Racing GP-5W Helmet SA2020.
ARAI GP-5W Removeable/Replaceable Cheek Padding
Low maintenance, easy-to-clean cheek pads are removable, washable, and replaceable with pads of varying thickness to provide a snug, safe fit.
Threaded for M6 HANS Anchors
The FIA-8859-2015 certified GP-5W helmet has M6 threaded washer/nuts with 6mm threads pre-installed. This convenient feature lets the driver use the anchor system that works best with their Head and Neck Restraint. The anchor posts are made to rest flush on the helmet surface, accepting a variety of HNR anchor systems.
Extraordinary Air Flow and Ventilation
Closed-cockpit drivers need greater airflow when racing. The upper ventilation system of the GP-5W SA2020 helmet incorporates two exhaust vents and two large intake ducts to help keep the driver cool and comfortable.
Multiple Shields Available for the Arai GP-5W
A variety of shields for the Arai GP-5W are available here. Arai anti-fog shields come in clear, light tint and dark smoke. Standard shields also come in clear, light tint and dark smoke.
The most effective helmet is one that fits properly. To measure your head, have an assistant use a dressmaker's tape or a piece of string to measure the circumference of your head. Start at a point about an inch above your eyebrows, looping around the back of your head at the point that results in the largest measurement, and finally around to the front again. It's a good idea to take two or three measurements to make sure you have the largest one.
This helmet will ship to you with signature required for delivery.
