Solo Series Sponsors

MiDiv Solo Series Sponsors

R & S Racing Inc. was founded in 1993 and is operated by Ron & Sonya Ver Mulm.
The lack of knowledgeable SOLO racing tire support in our area prompted us to become a Hoosier Racing Tire dealer in 1994.
We could always find a Drag Race or Stock Car tire dealer, who would order tires if we knew what we wanted.
We found the lack of knowledge and inventory of most dealers unacceptable. We obviously can’t stock every tire size and compound, but we have an extensive inventory and if we don’t have it in stock, we can “Drop Ship” from our warehouse which is located just down the street from the Hoosier Racing Tire manufacturing plant.
R & S Racing Inc. stocks Hoosier Racing tires for SOLO, Vintage, and Road Racing. We provide trackside service for SCCA SOLO in the Midwest, Central and Great Lakes Divisions, and at many SCCA National SOLO/ProSolo events around the United States.
We cosponsor the MiDiv SCCA Solo Series with Solo Performance Specialities.
We are the offical tire supplier for the Gateway Autocross Association.
We participate in SOLO Tour, ProSolo, and open track events.
In addition to competing, we spend 8-12 days per year testing tires for ourselves and the Hoosier Racing Tire. This ensures when you purchase tires from us the recommendations we give have been tested and verified, not just a guess or second-hand information.
We provide Real Racing WheelsHoosier Racing Tires and services, specializing in Autocrossing.
We also provide Trackside Tire Mounting, Balancing, and Tire Disposal service at an extensive number of events each year.
We keep our trackside service charges among the lowest in the industry and invest in the latest equipment to provide quick turnaround and limit the possibility of damage to your racing wheels. We take extra care to protect your investment in your wheels.
We also modify and fabricate cars and components in our shop, and provide computer chassis analysis to get your car set up with a minimum investment.
