Text messages have the 1st answer priority. Emails will be answered within 12 hours.
We kindly ask you not to send repeated inquiries. Multiple messages increase the number of requests, which leads to a longer response time. Submitting an inquiry only once will save time for both our customers and staff. Our goal is to provide the fastest support possible.
When communicating please include the following information if possible:
order number, original and current issue with the car, parts replaced, test and procedures done, history of the car (flooded, engine swapped, timing chain done, etc), any other information that might help to diagnose the problem (trouble codes, photos), scan tools available.
Please allow reasonable time for answer, especially if you are in a different time zone.
Remember more relevant information will bring about quicker and better answers.
