Brembo Front 365x29 Rotors & Four-Piston Calipers FITS: BMW Z4 (E89) The Most Sophisticated High Performance Braking System Ever Manufactured for Your BMW This is a lightweight two-piece rotor and caliper system for racing, track days, and high-performance driving. Brembo's GT System combines increased thermal capacity and lightweight characteristics of 2-piece floating rotors for an extremely versatile and durable system on or off the track. Brembo's GT Systems are designed and tested specifically for track-day enthusiasts and drivers who demand the utmost performance from their cars. These kits offer superlative performance for both everyday driving and demanding track-day sessions. The heart of the kit consists of monoblock aluminium calipers, machined from a single billet of cast aluminium to ensure outstanding rigidity and minimized deformation under heavy braking. The 2-piece floating rotors supplied in the kit feature an exclusive venting system that improves cooling capacity and increases resistance to cracking caused by thermal shock by over 40%. Cross-drilled and slotted finishes are designed and executed with meticulous precision. These features in the braking surface help dissipate heat and eliminate brake dust and gases. A set of high-performance brake pads with specific friction materials for the E89 Z4; TUV/DOT homologated metal-braided hoses; plus an adapter and high-quality fastener hardware complete the kit. Racing-Derived Monoblock Calipers in Billet Aluminium Lightweight, rigid and resistant to high temperatures, Brembo's GT-R calipers are made from billet aluminium with a radial 4-piston arrangement. They reduce unsprung weight, improving suspension dynamics and vehicle performance. These Brembo calipers are designed to provide constant, predictable braking strength and a stable, reliable pedal. Individual pistons with stainless steel radiators allow a significant reduction in heat transmission during extreme driving, reducing brake wear and fade to a minimum. Brembo GT-R calipers are nickel plated to guarantee protection against corrosion, providing longevity and high quality in the field. The Brembo logo is CNC machined in red embossing.   Two piece floating discs to reduce the suspended weight and dissipate heat quickly. GT-R braking systems include two-piece floating discs which reduce the suspended weight and dissipate heat quickly. The floating disc's anti-noise hardware is the direct result of Brembo's experience with brakes designed for Formula 1 competition. The discs are 365 mm in diameter and 29 mm thick.  Pads Provide Optimum Performance in Various Driving Conditions The GT-R range offers a series of friction materials able to meet a wide range of driving types. They offer optimum performance in various driving conditions, both on and off the track. In addition to the High Performance road pads, pads with racing/track friction material are also available. In order to guarantee correct installation without problems, the GT-R kit includes all the necessary hardware elements such as billet brackets and installation adaptors as well as stainless steel Goodridge brake lines.

DOCOL R8: The State of the Art in Advanced High-Strength Steel A few years ago, while attending PRI (the Performance Racing Industry trade show in Indianapolis), we were introduced to a newly-developed steel tubing product called Docol R8. It was designed to replace 4130 Chrome-Moly -- a World War II-era product -- in race car chassis and safety cage construction. We were intrigued. 4130 has always had its drawbacks as a metal used for impact absorption. It tends to get brittle when welded, and it lacks ductility (the ability to sustain plastic deformation under tensile stress before failure.)Docol is a modern, engineered Dual Phase Advanced High-Strength Steel (AHSS), replacing 4130 as the state-of-the-art material for race car chassis and safety cage manufacturing. We found that racing fabricators were switching to Docol R8. Engineered specifically for motorsports applications, Docol R8 is an improvement over 4130 in every way: Docol R8 is considerably stronger than 4130 CrMo. Tensile Strength of 116,000 psi vs 95,000 psi, Yield Strength of 100,000 psi vs. 75,000 psi. Docol R8's heat-affected zone (HAZ) is much smaller, meaning much less joint embrittlement from the heat of TIG welding. Docol R8 has a higher resistance to fatigue. Docol R8 is much more tolerant of heavy fabrication (such as tube bending and forming). Docol R8 is far more dimensionally consistent, with tube diameter variance of 0.3% vs. 10.0% in 4130 and wall thickness variance less than 1/3 that of 4130. So after extensive research, consultation with testing engineers, and discussion with professional race car fabricators, Competition Motorsport was the first major manufacturer to transition fabrication of all our bolt-in roll bars and harness bars from using 4130 CrMo to Docol R8. That was in 2018, and five years later we have had nothing but great experience with, and feedback about, Docol R8. Fortunately, we haven't had many customers tell us about accidents they've had that put the strength of their Competition Motorsport Performance roll bar to the test. But we have had a couple. In one case in particular, a customer told us his Competition Motorsport roll bar saved him from significant injury. He was hit broadside at an angle just behind the driver seat -- basically, right into the meat of the main hoop of his roll bar -- and the offending car didn't protrude into the cockpit even an inch further. Our own drivers have been amazed at the strength of Docol R8 under race conditions. We've had our share of race car "rubbing", and the parts fabricated from Docol are always amazingly intact.Is Docol more expensive than 4130? A little. But our prices have remained unchanged, because we believe in delivering a superior product at a competitive price. That gives us an edge, and it gives our customers an edge. That's why we design and manufacture every roll bar in-house, starting with straight bar stock and ending up with a beautifully TIG-welded roll bar. It's why we powder coat each one in our professional powder booth, on-site. And it's why we use advanced materials like Docol R8. We don't farm any of it out, because when we put our name on a piece of safety equipment, and we ask you to bolt it in your car and take it to the track, we don't take chances. The result is superior design, quality, and service, that you simply can't find anywhere else. You can pay more for a roll bar, but you can only get the best from Competition Motorsport.
