CMS Performance Roll Bar for S197 Mustang This Roll Bar Fits the Following Cars: Ford Mustang S197 (2005 -2014), all except convertible Click Here for Installation Instructions HANDS DOWN THE BEST ROLL BAR FOR THE S197 MUSTANG The CMS Performance S197 Mustang Roll Bar is the strongest, safest, and most beautifully constructed roll bar on the market. In designing the Mustang roll bar, safety, strength, and structural integrity were primary goals. That's why the CMS Performance S197 roll bar is fully TIG welded from ultra-strong Docol R8 Advanced High-Strength Steel sized 1.75" diam x 0.095" wall, vs. the mild-steel tubing others use. Docol R8 is 30-35% stronger than DOM mild steel and even 10-15% stronger than 4130 CrMo steel. This allowed us to design a roll bar that is stronger and lighter. Precision CNC machined interlocking roll bar clamps, made to our specifications in the USA, make joining the main hoop and kickers easier during installation while giving the CMS Performance roll bar a premium, finished look. INCREASE YOUR SAFETY AND LOOK GOOD DOING IT Safety is the main reason to install a roll bar in the first place. So the CMS Performance S197 Mustang Roll Bar is designed to place your harness shoulder straps at both the proper angle (0 to -20 ) and distance to the driver. The rear kickers bolt to a strong existing bulkhead, requiring no reinforcement plates beneath the floor pan. Our use of state-of-the-art Docol ultra-high-strength-steel tubing throughout allows us to keep the driver's rear view unobstructed by diagonal braces, which also keeps weight down. Every detail is engineered with safety and structural integrity as our primary goal. AMERICAN MADE AND HAND-CRAFTED COOL The second reason to install a roll bar is because it really complements the aggressive, race-inspired styling of the Mustang. We get that. So each bar is crafted by hand by master fabricators, TIG welded for the ultimate in durability, and custom powder coated in our facility (at no extra charge). We've color-matched powder to most of Ford's factory paint colors for a truly customized look1, or you can choose from thousands of custom colors and finishes to give your car a personalized look that will last. Going from raw Docol tube stock to a gleaming finish, every roll bar is handcrafted by our most experienced cage- and race car builders. Nothing is left to chance. The CMS roll bar is designed to give you an unobstructed view through your rear window. None of your plastic interior trim needs to be removed or cut, just a little carpet that is hidden away. So if you ever need to put your car back to stock, it will look as though the roll bar was never there. EASY INSTALLATION AND OPTIONAL HARNESSES COMPLETE YOUR SAFETY UPGRADE Complete, detailed instructions make installation pretty simple (figure about two hours if you're reasonably handy; having a buddy helps!) All the supplied installation hardware is American made: Grade 8 mounting hardware and an industrial carbide drill bit. So you don't have worry that you don't have what you need for a flawless installation. You can add four-point Schroth Profi II ASM Harnesses specifically designed for use in cars with no sub-strap cut-through in the seat (like the Mustang). Many customers also add CMS Locking Harness Collars to keep harness shoulder straps right where you want them (they're not required for safety, but a lot of people like the look!). CMS PERFORMANCE S197 MUSTANG ROLL BAR DETAILS Manufacturer: CMS Performance Manufacturer part no.: PRB197 Materials: Docol R8 advanced high-strength steel tubing 1.75 x 0.095; CNC-cut carbon steel mounting plates; CNC-machined solid steel interlocking roll bar joints Construction: full penetration 360º TIG welding Design features: one-piece main hoop and three-piece rear kicker make installation simple; allows full seat travel with any seat Weight: 52 lbs. (23.6 kg) Designed, built, and powder-coated by CMS in the USA Includes all necessary hardware including carbide drill bit Roll bar installation in the Mustang requires removal of the rear seats. This product is intended for off-road use only. 1 Note: CMS Performance powder coat colors are professionally matched to be as close as possible to factory paint codes. However, color-matching powder is not the same as mixing liquid paint. In a few cases, slight color variance is normal and is not perceptible with the roll bar installed inside the car.

CMS Performance Bolt-In Roll Bar for Porsche 911 (991 Gen) This Roll Bar Fits the Following Cars: 991.1 Porsche GT3 (2014-15) 991.1 Porsche GT3RS (2016) 991.2 Porsche GT3 (2018-19) 991.2 Porsche GT3RS(2019) 991.2 Porsche GT2RS(2018) 991 (all) Porsche Carrera/Turbo w/ factory sunroof (2012-2019)1 THE BEST ROLL BAR FOR PORSCHE'S TRACK ANIMAL The CMS Performance 991 Roll Bar is the strongest, safest, and highest quality bolt-in roll bar on the market for your Porsche 991 Carrera, Turbo, GT2RS, GT3 or GT3RS, period. In designing and building the CMS roll bar, safety and structural rigidity are our primary goals. That's why we fully TIG welded 1.75" Docol R8 Advanced High-Strength Steel tubing instead of the less-expensive but inferior 4130 CrMo others use. It's why CMS Performance uses the strongest chassis mounting points and cross-brace the main hoop. Click Here for Installation Instructions AMERICAN CRAFTSMANSHIP & ATTENTION TO DETAIL The CMS roll bar places your safety harness shoulder straps at the proper angle (0º to -20º) and distance (as close as possible) to the driver, regardless of seat position. CMS Performance uses thicker Docol tubing and main-hoop cross bracing to give you an unobstructed rear view without the need for additional bracing. That adds up to safety superior to that of other products we've seen for sale. CMS rear kickers bolt to the Porsche 991 rear shock towers (where the factory racing roll cage mounts), the safest, strongest mounting points. This adds rigidity to the chassis and suspension. The main roll hoop is mounted to the steel frame structure beneath the vehicle just like the factory cage. CMS PERFORMANCE MEANS STRENGTH & BEAUTY Fully TIG welded by master welders and professionally powder-coated in-house, the structural integrity, fit, and finish of the CMS Performance Porsche 991 Roll Bar is absolutely unsurpassed. CMS Performance offers a full range of powder-coat colors professionally matched to Porsche OEM paint codes.2 Or you can choose a custom color from thousands of Prismatic Powders shades, including, of course, a beautiful matte black if stealth is more your thing. Powder coating is included in the price of your CMS Performance roll bar. Superior engineering, design, quality, safety, and appearance at an affordable price, backed by our legendary customer service all add up to this: you can pay a lot more for a roll bar, but you'll only get the best from CMS. ADD RACING HARNESSES FOR SAFETY AND SAVINGS! Add six-point Schroth Enduro 2x2 GT3 , Schroth Flexi 2x2 GT3 , or Sabelt Silver Series GT3 , or four-point Schroth Profi II ASM GT3  harnesses to your order with our convenient pull-down menus above. These harnesses are specifically designed to bolt right up to your Porsche carbon lightweight bucket seats. (Porsche's passenger-side seat does not typically have a sub-strap pass through.) If you're installing six-point harnesses in your Porsche, we strongly recommend adding the CMS Performance Sub Strap Mounts to your order. They provide a solid, properly located anchor for your antisubmarine straps and are very easy to install. CMS PERFORMANCE PORSCHE 991 GT2RS/GT3/GT3RS ROLL BAR DETAILS 1.75"x0.095" Docol R8 Advanced High-Strength Steel tubing for superior strength Full-penetration 360o TIG welding throughout One-piece main hoop and three-piece kicker make installation so much easier CNC-cut precision mounting plates CNC-machined steel interlocking clamps ease installation US-made Grade 8 hardware included Full seat travel with any seat Comes with detailed installation instructions & all necessary hardware for a seamless installation This product is intended for off-road use only. 1 Be sure to select "Yes" under the Sunroof Version option above when ordering a roll bar for your 991 equipped with the factory sunroof. This version is slightly shorter than the non-sun roof roll bar. 2 Note: CMS Performance powder coat colors are professionally matched to be as close as possible to factory paint codes. However, color-matching powder is not the same as mixing liquid paint. In a few cases, slight color variance is normal and is not perceptible with the roll bar installed inside the car.

Arai Positive Shield Latch System The GP-7SRC ABP uses Arai's positive shield latch system to provide secure visor closure while retaining smooth and convenient visor operation. Updated shield pivot hardware incorporates a one-piece track slider and T20 Torx adjustment system. The lower shield pivot position also increases the smooth shell area above the visor opening, supporting Arai's focus on improved glancing-off performance. FCS Cheek Pad System Sculpted FCS cheek pads help provide a secure, encapsulated fit around the driver's lower jaw. The design helps reduce unwanted helmet movement while improving comfort and reducing wind noise at high speeds. HANS and FHR Ready Integrated M6 threaded mounting points are built into the GP-7SRC ABP for compatibility with approved HANS and other Frontal Head Restraint systems. A flat mounting surface surrounds each threaded anchor location so compatible restraint posts can seat properly against the helmet shell. Eject System Ready A pre-cut pocket beneath the crown pad allows the GP-7SRC ABP to accommodate an optional Eject emergency helmet removal system without requiring significant modification to the helmet interior. Drink Tube Compatible The removable center chin liner simplifies installation of a driver hydration system. Multiple routing options allow the drink tube to be positioned according to driver preference and cockpit configuration.

A2-266 Girodisc 2pc REAR Brake Rotors GT4 ClubSport This high-performance product is built to meet the demands of competitive racing. Designed for durability, precision, and track-day performance. Engineered for Performance on the Track This Girodisc system is a 380mm two-piece steel rotor and aluminum hat combination, a direct-replacement upgrade for the one-piece OEM GT4 Clubsport steel brakes. The A2-266 will bolt directly to the GT4 ClubSport and work perfectly with your OEM calipers. There are two main reasons for replacing your OEM rotors: first, the Girodisc rotors are designed to shed heat more effectively than the original rotors; second, the slotted Girodisc A2-266 will far outlast the OEM drilled rotors. When subjected to intense heat in a racing or track-day environment, the drilled holes in the OEM rotors originate cracks which can lead to rotor failure. When paired with the Girodisc A1-266 front rotors, your factory brake bias and ABS efficiency are maintained. When used with Pagid or PFC performance brake pads, and RF1 brake fluid (also available from Discovery Parts), 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 eight to ten 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.  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. Features: • Built for racing reliability and consistent performance • Compatible with demanding track environments • Designed for perfect fit and easy installation FAQs: Is this part track-proven? Yes, it has been tested extensively under racing conditions. Does it require professional installation? While not required, professional installation is recommended for best performance. Will this fit my vehicle? Please refer to the fitment guide or contact us to confirm compatibility. Can I return this if it doesn’t fit? Yes, as long as it’s unused and in original packaging.
