If you're not familiar with OCRC,
check my review of their last event.
Their next school is on 10-2 and 10-3, and this time I've signed up my wife as well. She'll be driving her Dinan S2 540iT and I'll be driving my Z4 MC. We might bring down my Dinan S2 M5 the second day and trade off. This is a very good school, and it's well worth the money! Think of it as 2/3 as good as BMW's Spartanburg school for 1/3 the $$$. And it's nearby in OC!
