Road Race Engineering by E-mail



We receive a large volume of mail everyday (from various sources), so PLEASE put "To ROAD RACE", or something like that, in the SUBJECT field of your E-mail. 

We will NOT be able to answer all the mail. please phrase your questions to be as specific as possible, and include all relevant specs needed (year, make, model, mods done, driving (street, rally, road-race, drag-race, etc.)). What we have found is that a very reasonable question can be asked, but we need much more info. This leads to many back-and-forth mailings, that require a fair amount of keyboard time, that all could have been done in less than 2 MINUTES on the phone! (and done better/more complete). Short yes and no questions  are usually answered the same day. Keep it simple. Story problems and essay questions can take up to a week to respond to, if at all.  The more time we spend building race cars, the less we have for long answers. We read all the mail and check it several times a day. If  you do not get an answer with in a few days, send a simple reminder.  Some mail does slip through the cracks, cranky reminders usually get the delete button. 

We can not do justice (via E-Mail) to questions like : "I want my 8 to be faster, what do you recommend". This is a long discussion, even on the phone. These will normally receive a "please review sections --- and ---- in the website", and then "call us" , response. Please use all the resources listed on our Tech Tips Pages and our forums at So Cal EVO. Also try to use the available resources at EVOM Club DSM and and 1000 Already Asked Questions. You will find that more often than not, someone has already been where you are going. Then again... remember that while half of your problems can be solved by sitting down and reading the internets, the other half can be solved if you just stop reading the internets!

Road Race Engineering by Telephone

We do our best pick up the phone starting at 10:00 am M-F. The best time to call is between noon and 7:00pm, California time, the hours we have the most phone support on staff. Non-standard we know, but given our location (Pacific coast) and our local customer base, we have found this works best. Guys need to have a real job to pay for all these mods. It gives the people that drive from all over So Cal the time to reach us; to get off work, let traffic cool down, and stop by the shop in the evening. We do what we can to answer it when we are not talking to someone else. After four rings it goes to voice mail, we return all messages the same day. Many people that we call back we get an answer machine or because of the time difference, they are off work. Leave a number where we can reach you in our afternoon or let us know what is a good time to call.

After 4:30 or so people start getting off work and stopping by to talk, have their cars looked at, pick up parts, drop off cars. We are located in one of the larger metropolitan areas in the US, and we ALWAYS have walk-in customers here. If we are all tied up talking to people that took the trouble to drive here, we may not be able to get the phone.

When you do get someone to answer the phone, the first thing everyone does is to ask for Mike. "I must speak to Mike, some magazine told me he is the guy"  If  I am not helping someone else, I'll get it. If you get someone else, give them a chance to do their job. I could get anyone to hand me the phone all day, I got these guys because they know their DSMs and EVOs. They were all customers once and have all  been where you are going. Between all of them, they have personally broke every part on their cars twice and had to fix it themselves after fixing your cars all day. Ask them your question !  If it is over their head, they can interrupt me and get you an answer. Some guys will call 5 times asking only for me when anyone else here could have helped them.

E-mail works good as a way to let me know what you are after. Essay questions, life stories and story problems can take up to a week to answer. The best questions are ones that we can go through and answer yes, no, $100, Thursday, 25psi...  We get 40+ e-mails a day that need to be answered, I have time for about 20 to 30 a day during the week. When we are racing that weekend things get pretty backed up.

Road Race Engineering In Person

We are open for walk in customers from 10:00 am till 7:00 pm for parts pick up. It is best to set up an appointment if you will be needing advise or having your car looked at. Before the UPS truck comes at around 5:00 we are extremely busy getting the shipping ready for the day, fixing cars that were previously scheduled,  and answering the phone. Do not stop by before 5:00 with out an appointment unless you are the most patient person in the world or just need to pick up a few parts and run. We can set appointments for parts pick up and advice later in the night. We really do have flexible hours if you plan with us ahead of time. Check ahead to see if we have the parts in stock.
