High-speed drifting and drag racing events will take place side-by-side at Sonoma Raceway this weekend with Sonoma Drift's Summer Jam, as well as Summit ET Bracket Drag Racing, Aug. 10-11.

The Summer Jam Series Championship event, which is hosted by Sonoma Drift, will take place on Turns 2-4 of the 12-turn road course, as the drivers work to control their high-horsepower car while it slides sideways at high speed.  Drivers are judged on execution and style rather than who finishes the course fastest.

Saturday will feature individual practice in the morning followed by tandem practice in the afternoon. Professional Formula DRIFT racers, including San Jose's Matt Field and Santa Rosa's Jason Bostrom will show off their skills during the practice sessions. Sunday's final competition is set to begin at 3 p.m. The grand prize winner of overall series points will be awarded $3,000. The winner will also receive free entry into future 2013 Sonoma Drift events.

Drifting action gets under way each day at 8:15 a.m. and admission is $15 per day for spectators (kids 12 and under FREE), and $20 for Sunday's show car registration. You can register your show car in advance by emailing bshaw@racesonoma.com or visit racesonoma.com/sonomadrift for more information.

In addition, the Summit ET Bracket Drags take over the lightening-quick quarter-mile drag strip with back-to-back days of straight-line racing. Featured classes include High School, Trophy, Motorcycle, Sportsman, Pro and Super Pro.

Gates open at 8 a.m., with racing spanning from 8:30 a.m.-5 p.m. Cost for spectators is $15, while cost for competitors is as follows: High School and Trophy ($25); Association classes ($35); Sportsman or Motorcycle ($40); Pro or Super Pro ($60).
