STR Autocross Project

Tire Rack and Grassroots Motorsports are excited to announce our drivers/test team will be returning in the 2010 Mazda MX-5 for another season of SCCA Solo competition and STR vehicle development. 2010’s competition success exceeded our expectations as the car and drivers scored:

• Three divisional championships
• Two ProSolo class wins
• Second place overall in the year-end ProSolo class standings
• Two Tire Rack SCCA National Championship trophy positions (6th and 9th of 51)
• STRL Tire Rack SCCA National Championship

The results were accomplished by resisting the temptation to throw all the go-fast parts at the car at the beginning of the season. Instead, we followed a systematic approach of installing and testing the major component changes so we could share the real world gains with readers along the way.

Plans are already in place for more car development and product testing -- a wet and dry extreme performance tire shootout, a brake pad comparison, further suspension changes and by popular demand, a heavy versus light weight wheel track test.

Do you have additional SCCA Solo-related comparisons you would like to see tested? Myths to bust or confirm? Give us your ideas below.
