They always had to meet two conflicting requirements in their product developments: On the one hand, the rim diameters and wheel widths are to become ever larger, but on the other hand, the designers are also to reduce the rim weight. AC Schnitzer engineers and designers have found a solution for this feat: technically particularly innovative and interesting in design. Thanks to their particularly innovative production method, the Type VIII Lightweight Wheels meet both criteria in an optimum manner. Due to their special design, they open up completely new design possibilities: numerous variants can be realized by combining a partially polished or lacquered surface. What is your personal benefit? - high quality lightweight wheels save approx. 25-35% weight, compared with conventional casted wheels - elegantly spun star-shaped centres - slender design of the wheels thanks to high strength material - perceptible reduction in unsprung mass and gyroscopic forces on the car, therefore - significantly improved driving dynamics - significantly improved acceleration and deceleration due to lower masses - improved cornering handling - machined original AC Schnitzer logo - high quality clear lacquer protects the wheel against corrosion, therefore - long-lasting - open design in BiColor, giving a clear view to the brakes\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMaterial\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAbout 97 percent of the melt consists of aluminium, but the remaining three percent of the wrought alloy also helps to influence the desired properties of the material for the ideal wheel. In addition to the main component aluminium, the alloy also contains one percent magnesium and one percent titanium each (which ensures finer grain size). The precise composition of the material alloy has a decisive influence on the subsequent properties of the wheel. Pure Aluminium Approximately 97 percent of the alloy consists of pure aluminium. The remaining three percent of the wrought alloy is important for the properties of the material. Chrome The AlCr20 master alloy with the hard metal chromium improves recrystallisation resistance. Master alloy means a mixture of aluminium with other materials, in this case it is a maximum of 0.25% by weight of chromium, i.e. a very small amount. Magnesium Together with pure silicium, magnesium leads to a higher strength of the total alloy. The maximum proportion of these materials is 1.2 and 1.3 percent by weight, respectively. Titanium These glossy ingots are the master alloy AlTi5B1, which serves a finer grain structure of the total alloy. The proportion of the expensive raw material titanium is only 0.1 percent by weight. Silicium These irregularly shaped lumps are only added to the alloy together with magnesium. This increases the strength. The silicium content is between 0.7 and 1.3 percent by weight. Manganese The addition of 0.4 to 1.0 % manganese makes the alloy tougher. Manganese has a positive effect on recrystallisation behaviour.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eManufacture\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eForging - an elaborate process that must offer maximum safety. In many steps the wheel is prepared for its important task for a long car life. The process control guarantees excellent material properties, which are the reason for the low weight of our wheels. Even in critical driving situations, these wheels offer the occupants optimum safety.\u003c\/p\u003e\n\u003cp\u003eStep 1: The nozzle\u003c\/p\u003e\n\u003cp\u003eA cast block more than 6 m long manufactured by OTTO FUCHS is the starting material from which a socket, which is precisely matched to the later wheel, is sawn off.\u003c\/p\u003e\n\u003cp\u003eStep 2: Pre-forging\u003c\/p\u003e\n\u003cp\u003eIn the first forging stage, the nozzle is pre-forged into a rotationally symmetrical blank with a force of 4,000 tons.\u003c\/p\u003e\n\u003cp\u003eStep 3: Design forging\u003c\/p\u003e\n\u003cp\u003eIn the second forming stage, the styling is pressed into the pre-forged blank under a 7,000 ton press, which gives the wheel its later appearance to a large extent.\u003c\/p\u003e\n\u003cp\u003eStep 4: Punching\u003c\/p\u003e\n\u003cp\u003eIn the last forging stage with 800 tons of pressing force, the later ventilation hole windows and the hub bore are punched out and the burr of excess material sheared off at the outer circumference.\u003c\/p\u003e\n\u003cp\u003eStep 5: Flow pressing\u003c\/p\u003e\n\u003cp\u003eThe outer edge of the blank is heated.

Now the surfaces, which are later to shine metallically bright, are turned off and then polished to a high gloss. Finally, a two-layer clear coat is applied, consisting of a polyester primer and the acrylic clear coat.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTest Procedures \/ Safety\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAfter their design, the first sample rims are manufactured under real production conditions. These must undergo a multitude of tests. Among other things, the strength is tested. The \"rim life\" is simulated in the bending circumferential test. Every AC Schnitzer rim must withstand this intact in order to be allowed to be produced and sold at all. This is followed by vehicle-specific tests, including test installations with check of unobstructed movement and driving tests on public roads and on race tracks. Only after these procedures our rims receive their homologation, i.e. the approval to be used in road traffic. Wheels are safety-relevant components. Therefore, they are checked and tested with the greatest care. This starts with the first chemical material tests and ends with hard testing machine endurance runs: - § 30 StVZO wheel guideline - ECE R124 - Bending-rotation tests - 90° impact test - unwinding tests\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eUniqueness of the lightweight rims Type VIII:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMade in Germany\u003c\/li\u003e\n\u003cli\u003eWeight-optimized\u003c\/li\u003e\n\u003cli\u003eDeveloped exclusively for BMW vehicles\u003c\/li\u003e\n\u003cli\u003eWith exclusive AC Schnitzer\u003c\/li\u003e\n\u003cli\u003eCompatible with standard RDC system - also available as a complete wheel\u003c\/li\u003e\n\u003cli\u003eWarranty 2 years\u003c\/li\u003e\n\u003cli\u003eProduction monitored according to ISO standard\u003c\/li\u003e\n\u003cli\u003eBi-Color Finish\u003c\/li\u003e\n\u003cli\u003eKDS mount for wheel alignment according to BMW specification is available \u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WJ Wheels","offers":[{"title":"5x120 \/ 19x8.5 ET43","offer_id":45867089625244,"sku":null,"price":914000.0,"currency_code":"KRW","in_stock":true},{"title":"5x120 \/ 20x9 ET22","offer_id":45867085627548,"sku":null,"price":1016000.0,"currency_code":"KRW","in_stock":true},{"title":"5x120 \/ 20x10 ET33","offer_id":45867086053532,"sku":null,"price":1016000.0,"currency_code":"KRW","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0566\/6534\/2108\/files\/AC_Schnitzer_Type_VIII_20_Wheel_for_BMW_M3_5-Series_M5_6-Series_M6.jpg?v=1766835092","url":"https:\/\/cargym.com\/en-kr\/products\/ac-schnitzer-type-viii-20-wheel-for-bmw-m3-5-series-m5-6-series-m6-7-series","provider":"CarGym","version":"1.0","type":"link"}
