The ARCA Menards Series West, formerly the NASCAR K&N Pro Series West, NASCAR AutoZone West Series, NASCAR Winston West Series, NASCAR Winston Transcontinental Series and NASCAR Camping World West Series, is a regional stock car racing series owned and operated by the Automobile Racing Club of America (ARCA) and the National Association for Stock Car Auto Racing (NASCAR). The series was first formed in 1954 as a proving ground for drivers from the western United States who could not travel to race in the more traditional stock car racing regions like North Carolina and the rest of the southern United States.
Races are held at oval tracks ranging from 1⁄3 to 1 mile (0.54–1.61 km) in length and on two road courses, 1.53 and 2.45 miles (2.46 and 3.94 km) in length. Most races are stand-alone events (i.e. not in conjunction with other NASCAR touring series), but there are four race weekends that are in combination with the NASCAR Cup Series.
Many of the ARCA Menards Series West drivers on the series are gaining experience with the hopes of moving up to one of the major NASCAR series, however some of the drivers are right at home in the series and have no plans of moving on. Notable drivers who participated in the series include Ryan Blaney, Kevin Harvick, Brendan Gaughan, Derrike Cope, Chad Little and David Gilliland.[1]
The other regional division at the Grand National level of ARCA is the Menards Series East.
History
[edit]

The Menards Series West began in 1954 as the Pacific Coast Late Model Division. Nine races were in held in the first year, many of which were held in California, in cities such as Oakland, San Diego, San Mateo and Gardena.[2][3] The inaugural series championship was won by Lloyd Dane driving a 1953 Hudson Hornet.[4]
Afterward, the series became known as the Grand National West Series, then the Winston West Series. At first, the series sanctioned races on dirt tracks and paved tracks, but as the series developed, more races were held on paved tracks, with the final race on a dirt track being held in 1979 until the series returned to dirt in 2018.[2] Though the series primarily sanctions races in the United States, the series has also traveled to Australia in 1988 and Japan from 1996 to 1998 for exhibition races. The series became the first series to sanction a championship race outside the United States in 1999, when the final race was held at Twin Ring Motegi.
In 2003, the Busch North Series was consolidated into the series forming the modern day series.[2] For the 2008 season, Camping World bought naming rights of the series, renaming it the Camping World West Series.[5] Two years later, K&N Engineering, Inc. replaced Camping World as the title sponsor.[6]
In 2020, the series became part of the ARCA Menards Series banner and was renamed to the ARCA Menards Series West.[7]

ARCA Menards Series West cars
[edit]General
[edit]As part of NASCAR's unification of the two Camping World Series in 2003, the cars can be either a 105-inch (2,700 mm, which had been used in the former Busch Grand National East) or 110-inch (2,800 mm, which had been used in the former Winston West) wheelbase. Cambered/off-set rear ends are not allowed.

The car bodies are typically a hand-built steel body, however teams may also use a one-piece composite body. The composite body is a "common" item that may be run as any manufacturer branded car (i.e. only one style of composite body for all four car manufacturers [Ford, Chevy, Dodge, Toyota]). Teams then "brand" the composite body by the grill opening, quarter window openings and the vehicle decal package (head lights, tail lights, etc.). Due to the introduction of the Car of Tomorrow in the NASCAR Sprint Cup Series, many of the vehicles on the series are old Sprint Cup cars. Another popular way to get a complete body is to buy a "cut-off" body from a Nationwide series team and mount it on a chassis.
Teams have an option of building their own engines or they may run a specification engine, similar to what is used in many short tracks. Both engines are V8, pushrod, 12:1 compression motors. "Built" motors are built to team specifications using any configuration of pieces as long as it still meets NASCAR specifications. The spec engine is built using NASCAR-Approved pieces that may be purchased from an approved supplier. The engines may be purchased as a kit or pre-assembled. All of the spec pieces are individually encrypted with a barcode for verification and tracking purposes and can be checked during the inspection process with an encryption reader.
When the series first started, the cars ran a V6 engine with a maximum 274 cu in (4,490 cm3) displacement and no compression limit . In the early/mid 1990s the V8 engine with a 9.5:1 compression and maximum 358 cu in (5,870 cm3) displacement was introduced to the series as an alternative to the V6 engines. Due to the decrease in popularity of the V6, it was phased out for the 1999 season. When the East and West series rules were combined, the compression ratio changed to 12:1.
Cars may use leaded or unleaded fuel. However, when running in conjunction with one of the three national touring (Truck, Xfinity, Cup) series, unleaded fuel must be used.

On November 4, 2014 at the SEMA Show in Las Vegas, NASCAR president Mike Helton unveiled a new body style for the K&N Pro Series based on the Sprint Cup Series Gen 6 models. The new body, developed with Five Star Race Car Bodies, is constructed of a composite laminate blend and designed with easily replaceable body panels, expected to shrink the costs of fabrication dramatically. The body style is eligible for use in both Menards Series competition and ARCA Racing Series competition, replacing the old Gen 4-style steel bodies after 2015, and the current one-piece composite body after 2016. The Chevrolet SS, Ford Fusion, and Toyota Camry bodies used in Sprint Cup are the basis of the new bodies. No Dodge option is available with this car.[8]
Along with all of ARCA and NASCAR's international series, the Menards Series have General Tire as their exclusive tire supplier.[9]
