From the owner

I purchased my 2015 Scion FR-S July 4th, 2014 by accident. I always knew I was going to get a track car and I wanted something light, quick, and reliable. After I finally settled on a 2014 FR-S, we discovered while doing the purchase paperwork that the Vin number associated with the car that I chose was registered as a 2015. It was the first 2015 in the state and one of the very first in the country. This came as a pleasant surprise because I knew they updated the suspension on the 2015 model and improved the handling. Back to back comparison of a 2014 vs 2015 confirmed it.

Regardlees, my mindset was, it's easy to add power, but hard to remove weight. So I decided to buy this car and turbocharge it. I figured, "brand new Subaru engine platform... They WILL turbo it in something, so it will be sturdy enough to turbo it." and I was right (ie 2015 subaru wrx). The first thing I focused on where wheels, tires, brakes, and life support mods. I needed to make sure the car would survive a track day. I bought the brake components, 1 of my 2 catch cans, and a Mishimoto oil cooler (I've since sold it for a different style). That setup worked great for the track but when I got to forced induction my plans took a slight change. I decided to supercharge the car instead of turbo because I too had discovered this thing called autocross. It was originally going to be a passing fancy. Something fun to do that I wouldn't take seriously. But I had a blast and got hooked. Turbo lag, 350 whp, and a 2700 lb RWD sports car do not mix well with autocross, so I opted for the response and more precise control ability of a supercharger. The intercooler it came with prohibited the continued use of my oil cooler, so I got the dual radiator oil cooler from Jackson Racing which uses a water/oil laminova style cooler. This car in its current configuration has run a 1:25 lap time at Roebling with the Porsche Club of America and it matched the lap time of a black group 2016 Porsche 911 GT-3 RS

Owners notes:

The Skunk2 race header eliminates the catalytic converter which bumps the car into DSP. However with a weld or bolt on cat it will drop back to STX. I choose to not cut into the exhaust and run in SMF as I take the rear interior out on autocross days and have similar competition in that class.

Beard vs EPIC Beard - Subaru STI - HUGE Autocross at Daytona Speedway

[BLOG] Going from a Mustang to a Subaru in Autocross

Once a year the Central Florida Autocross Region hosts an event at Daytona International Speedway. Though this year instead of being on the tiny gokart track it was in the gigantic guest parking lot. 

My competitor and good friend Ben had just bought a very nice set of adjustable coil over suspension. One of the best ways to dial it in is to simply get more seat time in the car. 

Holding on tight in this bumpy course

Some background. I have only driven one all wheel drive car before. a 2007 Subaru Forester converted to STI specs. Though I did do one run in Ben's car in December of 2015 but back when he was on Pirelli Super-Sport tires. I have about ~4 years of competitive driving experience.

The car is now on 265/35/18 Bridgestone RE-71R tires, with full bolt ons, a turbo swap, and a MCS coilover suspension (more detail below).

This car was just stupid amounts of fun to drive. Ben says its putting down around 340(wheel HP) and 360 (wheel TQ). We were running the car on a lower boost tune due to the excessive heat that day and to be honest it still felt more powerful than my Mustang which makes about the same to the wheels. The power just SURGES on with minimal turbo lag. I still had to slightly change the way in which i drive. Was a bit strange going into a turn and putting my foot to the floor in order to spool up the turbo for the exit. In the Mustang this would be very bad and result in massive amounts of over-steer (running into crowds of people). My strategy seemed to work pretty well and I became very attuned to the car quickly. I placed 1st out of 6 competitors that day, and a ~20th raw time out of 120.

Back to the suspension and the whole reason I was co-driving. Ben's new adjustable suspension was made out of some kind of dark unicorn-magic. The course at Daytona was very bumpy and I actually managed to slightly sprain my arm that day from the ultra death grip i put on the steering wheel when I drive. After that first run though we dialed down the stiffness and the bumps just went away. Really goes to show you that a very expensive suspension system won't necessarily make you faster but can make you more consistent. This particular suspension was a Motion Control System (MCS). They usually run in the upper 4k-5K ranges and are very high quality. 

We managed to each bring down our times and clean up our runs by the end of the day. Mission success and I hope I helped out Ben by showing him a different driving style and giving him more runs to dial in the suspension! See Ben's build page on our site and follow us on YouTube to see how the competition goes this year against him!
