3rd Time’s the Charm…Racing at the SCCA Nationals

We all know the saying the 3rd time is the charm and this year’s SCCA National Championship Runoffs was no exception to the rule.  The past 2 runoffs I have not made it to the finish line.  In 2016 at Mid-O I was hit on the first lap and punctured my left front tire.  At Indy, I retired as we developed a fault in the ECU from some beta software we were running and the car dropped into limp mode and I wasn’t able to maintain full throttle.  

We have been working on the brakes for the past 3 years and during the season it limited us from running the car as much as we like.  We have also been chasing a fault/error with the ECU/control system of the car. We were still able to get the car enough starts and race finishes to get qualified for the runoffs in Sonoma.   Granted the car was not happy at most of those races and it was a struggle to get to the finish.

2 weeks before the runoffs we sorted out the ECU problem and were confident enough in the car to race it.  The backup plan was to race my Spec Miata if we couldn’t get the Mazda 3 fixed as I ran it this past season as well and had enough starts/races.

With the Runoffs at Sonoma, it was within 1-day driving distance unlike the past 3 runoffs at Daytona, Mid Ohio, and Indy so I got to try out the new (to me) truck and trailer.

I had raced at Sonoma one time prior, so the track wasn’t totally unknown like Mid-O and Indy, which all I had was simulator time so I was able to get up to speed quickly on a test day and find out what I needed to work on for chassis setup and driving.  The driving was easy to adjust, look at the data, see where the driver was sucking, and had to man up to keep a foot to the floor in some sketchy corners.

The car, on the other hand, had what we call “a good problem to have”, too much power.  We have been running a torsion-style differential in the car which works pretty well in a straight line and relatively flat tracks.  Sonoma is not a flat track that unloads the car 3-4 times per lap. With the Mazda 3 and the amount of torque, it makes means I was unloading the tire enough for it to spin the inside tire.  Most people think what is the big deal with a little tire wheel spin? It is a problem when you enter turn 10 at Sonoma at 97MPH and you start lighting off your right front tire. Look at the picture below and you can see that the front inside tires are barely on the ground and the rear isn’t.  The speedometer would jump around and you could see the right front wheel speed turning at 5-10 mph more in the data.

Mazda CorkSport car racing

We tried several suspension changes and driving style changes to make the best of it but in the end, we were way off the pace by 2-3 seconds of the rear-wheel drive cars in the class.

The good part about not being at the front of the field, there was zero stress when race day came.

Like any race there was a fun challenge, we would be heading into turn 2 blind as the race was at 4 pm in the afternoon and the sun would be shining directly down the hill.  Since I wanted to see the end of the race I was a little cautious at the start and Ali in the other Mazda 3 got around me at the start.

We fought it out for 8 laps and he went into turn 6 too hot and I was able to get under him and pass him on the inside.

After a few laps I put a 4-5 second lead on Ali I was basically in no man’s land, slower than the front guys and faster than the back half of the field so I spent my time working on tire management (it is easy to overheat your left front tire at Sonoma) and made it to the end of the race.

My official finishing place was 10th but after some adventures in tech, I was moved to 9th in the final results.  This isn’t where I wanted to be by any means but the 3rd time was the charm and I made it to the end of the race.

Huge thanks to the support we get racing the car from CorkSport, BFGRacing, Monarch Inspections, G-Loc Brakes, and Mazda Motorsports.

Working on the Driver

I have been racing Mazdas on the track in wheel-to-wheel competition since 2013 and I have learned quite a bit.

I am nowhere near being the best driver. I have good moments and plenty of “WTF Derrick” things which happen on the track which are masked by good car control.

2 years ago I bought a Spec Miata (SM). Locally the number of B-Spec and Touring 4 classes are smaller.  This is not great for me, as I find my racecraft suffers when I get too big events where there are more than 5 cars and the racing is close.  I can always fight my way to 2nd or 3rd place but the top step has been elusive.  Don’t get me wrong, I can go to events where there are other T4 cars (they are not unicorns) but the travel cost, time away from CorkSport, and fuel gets pricey really quick when constantly towing to southern California.

I took the SM out a few times last year and found I was way off the pace I needed to be to even get into the top 25% of a Ppec Miata field at any events.  The Northwest has a really strong group of SM racers who are more than happy to beat the illusion out of you that you can drive fast on the track.

This year I have been working on the car setup and updating the drive train to the best I can get for my car.  I worked with Haag Performance to get one of their SM 1.6 engines which have been winning races up and down the west coast. I have been also talking with Joe Jordan on car setup and general SM advice as he has gone down this road before with multiple SM drivers including Joey Jordan and Will Rodgers to get them to the top.

Before the season started I knew I wanted to get some top-level coaching so I looked locally at Pro Drive Racing which offers race school for SCCA certification and high-performance driving classes.  After few emails finding which event I should show up with my SM it was determined the June 5th high-performance school would be the best bet and I could get someone on one coaching with Todd Harris the head instructor.

I have struggled with the braking too much in the corners, as past instructors/coaches I have consistently mentioned this to me. I needed to overcome this if I was going to have a chance to match times with the top 25% of the field. With Todd strapped into the “Thrill Seat”, we hit the first session at speed so he could see how/what I doing and work on it.

This was a good news and bad news sort of ride.  He found my approach and driving style to corners works but it was not the fastest way through them – I was giving up cornering speed and to be able to get back to the throttle quicker. By simply backing up my braking zones I had more control in the corner which allowed me to stay committed to the throttle without having to modulate it after the steering wheel was turned.  This doesn’t seem like a huge thing but the feedback from the SM was drastically different. I was able to roll speed into the corners and carry a few more MPH. Heading onto a straightaway this is huge. I spent the rest of the day fine tuning the changes and making sure they stuck with me.

By the time this blog goes up, I will have raced again at the Oregon Region SCCA event at Portland Intl Raceway and found out how much the school improved my driving technique.  If I don’t screw it up too bad I should be able to take a second out of my lap times which in SM is HUGE! The weekend of June 29th I will be at Sonoma racing against 40 other SM drivers to really get a feel for where I am at skill level wise, I am prepared for this to be humbling, lol.

So, my advice to you, if you ever have a chance to take a driving school I really recommend it and specifically Pro Drive if you are in the Portland Oregon area.  They run a great program and you get one on one seat time with some of the best local drivers and instructors.

Look for future updates here at the CorkSport the blog on how it went.
