Services & Classes


We appreciate our customers and want them to make an informed decision.  Not everyone can attend SEMA or PRI, and with your day to day duties you may not have time to call the manufacturers direct. That is why we have the manufacturers come to CSS to give class on their products and answer any question you may have regarding their products for your build. 

These are not sales classes, these are informative classes based on YOUR input. No class will be the same.

Food is provided during the classes...we do not want you to be Hangry


If you would like to attend an upcoming class, please scroll through the upcoming classes below. Print out your form from the provided link and return it to the store with payment.  Due to limited seating, we offer pre-registration, this also comes with a discounted rate. Make sure to like and follow our social media pages for updates and info regarding these classes.  Like us on Facebook -- Follow us on Instagram
