Registration

The registration logic between the Championship Main Events (Sunday) and Practice Race Events (Saturday) is the same:

You have to renew your registration for each event of the championship
Separate registration lists between Saturday (Practice Races) and Sunday (Championship Race after Weekday Qualifying)
Registrations for every race weekend usually open on Monday of the same week
After submitting your registration for this week's championship event, you can immediately join the championship qualifying server by default* **

*Usually, you will immediately be able to connect to the qualifying server successfully. Until the next automatic 2-hourly restart of the qualifying server, you might see a different skin than the booked one on your car on this server. This condition always gets corrected by the next 2-hourly autorestart of the server.

**Only in rare cases, joining will continue to fail with the message "No slots available". If this continues to happen more than 2 hours after submitting your championship event registration for the week, please inform the @Orga team in our community discord's #drivers channel.

Cars

Bizzarrini GT 5300 Corsa

Bizzarrini, after contributing to Ferrari and Lamborghini, created the 5300, the first car fully credited to him, putting him in competition with his former employers. The 5300 project originated from his work with Bertone and Iso Rivolta, specifically the Iso Rivolta 300, which used a Corvette V8 engine. Bizzarrini wanted to race, but Rivolta initially disagreed. Eventually, Rivolta financed the more sporting Iso Grifo, the 5300's predecessor. The 5300 and Grifo shared the Iso Rivolta 300 chassis and independent suspension but had a shorter wheelbase. Breaking with Italian tradition, Bizzarrini used a reliable and powerful Chevrolet V8 engine, tuned to 365 bhp, and strategically placed it in the chassis for optimal weight distribution. A competition version with racing features was also offered.

Chevrolet Corvette 1967

The second-generation Corvette (C2), known as the Sting Ray (1963-1967), evolved from experimental racecars designed by Zora Arkus-Duntov and Bill Mitchell despite a racing ban. Zora championed the innovative independent rear suspension, a game-changer for American performance cars. While Zora was against the split rear window due to safety concerns, it was retained for the 1963 model year only. The C2's debut was impactful, boasting a distinctive design and performance. Small changes came in 1964, and the C2's powerful L79 327ci engine (1965-1968) also boosted the performance of other Chevy models.

Ferrari 250 GTO

The 250 GTO model was the pinnacle of the development of the 250 GT series in competition form, whilst still remaining a road car. It made its public debut at the annual pre-season Ferrari press conference in January 1962, and was the only front-engined model on display, with its monoposto and sports racing counterparts all having a mid-engine configuration.
The 250 GTO was the ultimate expression of the Ferrari 250 GT car. It was equally at home on the road or track – perhaps the last dual-purpose road/race car produced – and has achieved legendary status amongst aficionados of the marque. With only a relatively small production run of thirty-six cars, and with many of the examples produced having a great racing pedigree, it has become one of the icons of Ferrari's production history, with a revered position in collectors' circles.

Ferrari 250 GTO Series II

The first Ferrari 250 GTO was built in 1962, with bodywork refined by Scaglietti. In 1963, an improved version designed by Pininfarina, sometimes called the Series II or '64 GTO, was introduced, but only three were originally made. When the FIA rejected the homologation of Ferrari's mid-engined 250 LM for the 1964 season, Ferrari had to rely on the GTO. To keep the GTO competitive, revisions were necessary. The chassis had to remain the same, but a wider track was allowed. The engine remained largely unchanged with slight tuning modifications. The Pininfarina-designed body for the '64 GTO was lower and wider, but the shortened frontal area created more drag than the original.

Ferrari 275 GTB Competizione

In 1965, Ferrari introduced competition versions of the 275 GTB to compete with the Shelby Cobra, producing two limited series: ten "short-nose" cars in 1965 and twelve "long-nose" cars in 1966 (designated 275 GTB/C). These Series II cars resembled regular long-nose Berlinettas but featured a lighter, stiffer chassis, thin aluminum body, race-tuned V12 engine with dry sump, and race-developed independent suspension.
These were thoroughbred racers, the last GT cars built by Ferrari's competition department, born from the FIA's rejection of the mid-engined 250 LM's homologation in 1964. After initial homologation issues with the 275 GTB, Ferrari finally secured approval. The initial short-nose versions were similar to road cars, but with aluminum bodies and a six-carburetor setup.
The 1966 long-nose Series II featured a super-light aluminum body, dry-sump lubrication, a triple-carburetor assembly (due to a homologation error), higher compression ratio, and Nimonic steel valves. The transaxle had a magnesium alloy casing, close-ratio gears, and a strengthened limited-slip differential. Weight reduction included magnesium alloy covers, drilled panels, and a stripped-down interior with Plexiglass windows. Twin fuel tanks and bumpers were still fitted to maintain a "standard" appearance. 275 GTB/Cs achieved class wins at prestigious events like Le Mans and the Targa Florio.

Shelby Cobra 289 Hardtop

Cobra roadsters are known for power and style, but not aerodynamics. Shelby realized his racers needed streamlining for Le Mans to compete with the faster Ferrari 250 GTOs. Ford supported Shelby in 1963 to beat Ferrari, resulting in two Cobras built for Le Mans. One had an aluminum alloy hardtop to increase speed and finished 7th overall, behind three Ferrari 250 GTOs. This hardtop and other modifications like a larger fuel tank and vents were aimed at Le Mans victory. Stirling Moss managed the entry, but engine trouble caused early retirement. This marked the beginning of the Cobra-Ferrari rivalry at Le Mans. The color schemes were inspired by NWRAP's skinpack.

Shelby Cobra 289 Competition

The Cobra combined Ford's V8 power with AC's chassis, becoming a successful English-American hybrid thanks to Carroll Shelby's refinement and Ford's funding. AC Cars modified their Ace chassis to accommodate Ford's V8, initially the 260 cu in, later upgraded to the 289 and the 427 with a stronger chassis. The Cobra quickly won races due to its excellent power-to-weight ratio, with a 289 Daytona Coupe placing fourth at Le Mans. Shelby Cobra 289 Competition models were factory-spec roadsters with features like a bonnet scoop, roll bar, Halibrand wheels, flared wings, competition brakes, dual fuel tanks, racing seat, and a full race-spec 289 V8 with Weber carburetors and high compression.

Shelby Mustang GT350R

The 1965-67 Shelby GT350 was a performance-focused car, with 34 "GT350R" race-spec cars built for SCCA competition, winning the B-Production championship for three years. Mustangs were stripped and sent to Shelby for modification. They received a fiberglass front apron, fender flares, Plexiglas windows, suspension modifications, traction bars, a new differential, and a roll cage with a 34-gallon fuel tank. The suspension was upgraded with Koni shocks, larger brakes, and a beefier rear-end. The 4.7-liter V8 produced 306 bhp in street trim, while the 'R' competition cars had a blue-printed version making 340-360 bhp. Ken Miles debuted the GT350 R in 1965, winning its class, and the GT350 went on to a successful season with drivers like Jerry Titus and Mark Donohue.

TVR Griffith Series 200

Jack Griffith, a sports car enthusiast and former Cobra retailer, aimed to create a car surpassing the AC Cobra. Teaming with TVR distributor Dick Monnich and engineer Mark Donohue, he fitted a Ford 289 V8 into a TVR Grantura III. Griffith secured US marketing rights in 1964. Inspired by Carroll Shelby, Griffith aimed to build a superior car. In 1965, a Griffith 200 briefly led factory Cobras at a race. However, Griffiths were known for overheating, electrical issues, axle failures, leaking gas tanks, and fiberglass body mounting issues, making them challenging to drive.

Tracks

Riverside

Riverside International Raceway is a track that bakes under the desert sun, a place where dust swirls and challenges visibility. Its demanding layout, particularly the uphill esses right after the start/finish, tests both car and driver. The track surface, often bumpy and unforgiving, demands respect. While offering some straights for potential overtaking, the real challenge lies in maintaining momentum through its winding sections. The desert heat and the relentless nature of the track mean that stamina is key. Taming Riverside requires a balance of raw power and careful car placement.

Stardust

Stardust International Raceway is a flat-out speedway punctuated by challenging infield sections. The oval portions encourage high speeds and close racing, while the infield tests car handling with tight corners and elevation changes. The transition between oval and infield demands a versatile setup. Finding the right balance between straight-line speed and cornering grip is key to a fast lap. The unforgiving walls and limited runoff areas demand respect. Overtaking opportunities abound on the oval, but require bravery and precise timing in the infield. Mastering Stardust means conquering both the high-speed oval and the technical infield, finding the perfect compromise for a thrilling ride.

Laguna Seca

Laguna Seca is a circuit of dramatic elevation changes and iconic corners. The blind crests and plunging turns demand absolute commitment and precision. The track surface undulates beneath the wheels, making car setup crucial. The Corkscrew, a legendary downhill chicane, requires a leap of faith and a perfect understanding of the car's balance. Overtaking is a challenge, demanding bravery and exploiting even the smallest opportunities. Mastering Laguna Seca means dancing on the edge of control, finding the limit, and pushing just beyond it.

Paramount Ranch

Paramount Ranch is a tight, twisting circuit nestled in a picturesque setting, but don't let the scenery fool you. The track is a relentless series of corners, demanding precise car placement and quick reflexes. Its short straights offer little respite, placing a premium on momentum and cornering speed. The varied surfaces, from smooth asphalt to dusty patches, test a driver's adaptability. Overtaking is a real challenge, requiring patience and a willingness to exploit any opening. Taming Paramount Ranch is about mastering the art of the short track, maximizing every inch of pavement, and maintaining focus from start to finish.

Watkins Glen

Watkins Glen is a high-speed, flowing circuit that rewards bravery and precision. Its long, sweeping corners demand a car that is stable and responsive. The "boot" section adds a technical challenge, requiring drivers to find the right rhythm. The elevation changes and blind crests test a driver's commitment. Maintaining momentum is key, as even the slightest mistake can upset the car's balance. Overtaking is possible but requires a daring move and perfect timing. Conquering Watkins Glen means finding the flow, trusting your instincts, and pushing the car to its absolute limit.

Bridgehampton

Bridgehampton is a fast, undulating road course that demands courage and precision. Its blend of high-speed sweepers and tight corners tests every aspect of a car's handling. The track surface, known for its bumps and imperfections, requires a compliant suspension setup. Blind crests and challenging cambers add to the complexity. Maintaining momentum is crucial, as losing speed can be difficult to recover. Overtaking is a risky proposition, requiring careful planning and nerves of steel. Mastering Bridgehampton means attacking the track with confidence and finding the delicate balance between speed and control.
