Hey all, if there is anyone needing to get their competition license, there will be a Rush only comp school at MSR Houston, December 2-4 (That's Tuesday-Thursday). You will leave this event with a full competition license, no future provisional periods or races.

Rush of Central Texas will be there to support drivers in the event that repairs are needed in order to keep the cars running, so nobody has to go home early and waste their money in the event of a mechanical issue.

The price is $2350 with your own car. I cannot speak with certainty, but if you do not have a Rush for the event, Rush of Central Texas may have rentals available.

The school requires 6 drivers, and we currently have 5.
If you or anyone you know needs a comp license, sign up, or contact ROCT or MSR Houston. Having an SCCA or NASA license will allow you to race at almost any grassroots motorsport event in the country.
