Background: Kulwicki grew up in Greenfield, Wisconsin, a suburb of Milwaukee known for its Polish-American neighborhoods, near the Milwaukee Mile racetrack. After his mother died, his family moved in with his grandmother, who died when Kulwicki was in seventh grade. A year later, his only brother died of a hemophilia-related illness. Kulwicki attended Pius XI High School, a Roman Catholic high school in Milwaukee, and received a bachelor of science degree in mechanical engineering from the University of Wisconsin-Milwaukee in 1977.
Context: Kulwicki began his racing career as a 13-year-old kart racer. His father built engines as the crew chief for Norm Nelson and Roger McCluskey's United States Automobile Club (USAC) racecars. Because his work involved travel, Kulwicki's father was unable to help his son at most kart races, so Kulwicki's resourcefulness was often tested trying to find someone to transport his kart to the track. Even when Kulwicki asked his father for advice, he typically ended up doing most of the work himself. "I showed him how", Gerry Kulwicki said. "And he said: 'Why don't you do it? You can do it better.' And I said, 'Well, if you do it for a while, you can do it better.'"  Many local-level American racetracks host their own season championships. In Wisconsin, numerous locations held dirt and asphalt short track racing. Kulwicki started driving stock cars at the local level at the Hales Corners Speedway and Cedarburg Speedway dirt oval tracks. In 1973, he won the rookie of the year award at Hales Corners Speedway in the Milwaukee suburb of Franklin, and the next year started racing late models - the fastest and most complicated type of stock cars raced at the local level - at the same track. That season, he won his first feature race, at Leo's Speedway in Oshkosh.  Kulwicki moved from dirt tracks to paved tracks in 1977. He also teamed up with racecar builder Greg Krieger to research, model, engineer, and construct an innovative car with far more torsional stiffness than other late models. The increased stiffness allowed the car to handle better in the corners, which increased its speed. Racing at Slinger Super Speedway, he won the track championship in 1977. In 1978, Kulwicki returned to Slinger; that same year he started racing a late model at Wisconsin International Raceway (WIR), finishing third in points in his rookie season at the track. In 1979 and 1980, he won the WIR late model track championships.  In 1979, Kulwicki began competing in regional to national level events sanctioned by the USAC Stock Car series and the American Speed Association (ASA), while remaining an amateur racer through 1980. When Kulwicki raced against future NASCAR champion Rusty Wallace in the ASA series, the two became friends. Kulwicki's highest finish in the ASA season points championship was third place, which he accomplished in both 1982 and 1985, with five career victories and twelve pole positions.
Question: did the stiffness help?
Answer: The increased stiffness allowed the car to handle better in the corners, which increased its speed.

Background: Gwen Renee Stefani (; born October 3, 1969) is an American singer, songwriter, fashion designer, and actress. She is a co-founder and the lead vocalist of the band No Doubt that experienced major success after their breakthrough studio album Tragic Kingdom (1995) along with various successful singles, including "Just a Girl"
Context: Stefani made most of the clothing that she wore on stage with No Doubt, resulting in increasingly eclectic combinations. Stylist Andrea Lieberman introduced her to haute couture clothing, which led to Stefani launching a fashion line named L.A.M.B. in 2004. The line takes influence from a variety of fashions, including Guatemalan, Japanese, and Jamaican styles. The line achieved popularity among celebrities and is worn by stars such as Teri Hatcher, Nicole Kidman, and Stefani herself. In June 2005, she expanded her collection with the less expensive Harajuku Lovers line, which she referred to as "a glorified merchandise line", with varied products including a camera, mobile phone charms, and undergarments. In late 2006, Stefani released a limited edition line of dolls called "Love. Angel. Music. Baby. Fashion dolls". The dolls are inspired by the various fashion that Stefani and the Harajuku Girls wore while touring for the album.  In late summer 2007, Stefani launched a perfume, L, as a part of her L.A.M.B. collection of clothing and accessories. The perfume has high notes of sweet pea and rose. In September 2008, Stefani released a fragrance line as a part of her Harajuku Lovers product line. There are five different fragrances based on the four Harajuku Girls and Stefani herself called Love, Lil' Angel, Music, Baby and G (Gwen). As of January 2011, Stefani has become the spokesperson for L'Oreal Paris. In 2016, Urban Decay released a limited edition cosmetic collection in collaboration with Stefani.  In 2014, Stefani announced the production of an animated series about her and the Harajuku Girls. Along with Vision Animation and Moody Street Kids, Stefani has helped create the show which features her, Love, Angel, Music, and Baby as the band, HJ5, who fight evil whilst trying to pursue their music career. Mattel have signed on as the global toy licensee and the series itself, Kuu Kuu Harajuku will be distributed worldwide by DHX Media.
