I’d be willing to bet 90% of the people who read this blog know the car I’m about to feature. It isn’t one of those cars that’s known because it has 11ty billion dollars worth of body work or a huge stereo. This car is known because the car is a subtle well built 2005 Subaru Impreza WRX STI with all the right parts.
About Dan aka BoostJunkie:
Dan began doing HPDE events in 2004, right after he bought his STi. A family friend suggested that Dan and his dad sign up for an event at VIR. No question, Dan was hooked.
Dan began branching out to other organizations like NASA, Mazdadrivers, Audi Club, Mercedes Club, and TrackDaze.
After he graduated college Dan decided to change the 2005 Subaru from a daily driver into a full time race car. At the beginning of the 2009 season, he completed a NASA TT license evaluation and went on to do a full season in the TTS class. Dan won the season championship for his class. Winning the class championship is a huge accomplishment and shows Dan’s dedication and ability.
Every (ok 90%) of STi owners think it wont be necessary to modify their new car and we’re all wrong. Dan is no different and if you have followed Dan’s car over the last few years you know this is true. Dan had the opportunity/pleasure to work with the Myles @ Race Comp Engineering, this was two fold. RCE helped Dan learn the technical aspect of suspension tuning and RCE also began using Dan’s car to test new products on the street and track.
Over the next few years, Dan’s 2005 Subaru Impreza WRX STi went through many different suspension setups, and continued to modify other aspects of the car as well. Initially the goal was to create the ultimate dual purpose street and track car, and he was able to find a good balance between the two. A year or so ago, Dan got to the point where he was able to turn the car into a purpose built race car. Doing so is alot harder than it sounds. Turning a Street Car into a purpose built race car is more than “gutting and caging”, Dan learned this first hand.
Dan trusted IAG Performance in Westminster, MD with building a custom roll cage. A huge amount of weight was removed from the car, which meant pulling out all of the HVAC components, gutting the doors, and basically taking out everything in the car that wasn’t serving a purpose on track. The incredible increase in chassis stiffness required a suspension setup to match, so a set of JRZ RS Pro dampers were installed. IAG rolled and pulled the fenders to make room for a set of 275/35/18 Hoosier R6’s mounted on Enkei NT03+M’s in 18×9.5 +40. Leaving no aspect of the car’s setup untouched, a SARD carbon kevlar wing and a custom alumalite front splitter were installed to add some much needed downforce. Dan spent many hours stripping the cabin wiring harness and rewiring most of the electrical components to reduce weight.
Once the car was back together, Dan focused on dialing in the new suspension and getting used to driving the car. Dan’s lap times continued to shorten once Dan started fine tuning the new JRZ RS Pro’s. The car was now able to compete with the front runners in its class, and with a win and a second place finish in the two races during the second to last race weekend of the year, Dan had secured the TTS Championship.
The final race weekend of the season at Summit Point started off well, and Dan took second place on Saturday behind a very fast Corvette Z06. During the Sunday morning warm-up, the car suffered a brake line failure while entering Turn 1 at nearly 150mph. The car entered the gravel trap sideways and rolled 3 times, landing on the other side of the tire wall. Miraculously, Dan suffered only minor injuries and was able to climb of the car under his own power. The car, on the other hand, was damaged beyond repair. However, Dan already has started to rebuild the car, and already has a GD Impreza chassis to work with. With any luck, we will see a new and improved version of the car during the 2010 season.
Dan’s relationship with RaceComp Engineering goes back to 2005, when he began working there. Throughout the years, they have provided many parts for the car, including their swaybars, kool brake kit, GTWorx camber plates, and many parts from other manufacturers. They have also provided a great deal of input for chassis setup. Myles Williams, the company’s founder, has given Dan personal driver coaching, drawing on his many years of racing experience.
IAG Performance in Westminster, MD came on board as a sponsor about a year ago. They have done extensive fabrication work on the car, including the construction of the roll cage. They have also provided their header and external wastegate uppipe, as well as a few miscellaneous parts. IAG has performed much of the maintenance work on the car, including regular alignments, tire mounting and balancing, and ECU tuning. They have committed to being a key part of the build process for the new car, and even provided the chassis as a starting point. Their meticulous attention to detail produces incredible results, and their support has been essential to Dan’s success over the past season.
JRZ Suspension Engineering:
JRZ joined this project in the middle of the 2009 season, providing a set of their 2-way adjustable RS Pro dampers. They are externally adjustable for both compression and rebound, and also feature remote fluid canisters and adjustable nitrogen pressure. Their build quality and performance are both outstanding. Bryan Hise, the east coast representative for JRZ USA, has offered invaluable support and setup help.
Stoptech provided one of their front big brake kits for this project, featuring ST-60 6 piston calipers and 355x32mm rotors. They have also offered ongoing support, supplying replacement rotors and a great deal of expertise pertaining to pad selection, operating temperatures, and more. Dan plans to continue his relationship with Stoptech and use one of their big brake kits on his new STi build.
Kaminari Aerodynamics/Racetech North America:
This past season, Kaminari supplied a set of their race lateral links, featuring 6061-T6 seamless tubing and rod ends that are rated at 28,000 lbs. They also provided a pair of their brake duct inlets, essential in feeding cool air to the front brakes. Dan also uses a Racetech RT4009HR seat, although he purchased it before his sponsorship agreement with Racetech North America. He is looking forward to working with them on his new project, as the quality of both their aerodynamic and mechanical parts is top notch.
Dan’s 2005 Subaru Impreza WRX STi was an amazing car and we all were stunned when we heard of his accident. Dan being “Ok” after his accident says a lot about Subaru and IAG’s cage work. This is a risk all of us take while we’re track our cars but we can choose to build and own safe cars.

One thought on “Boostjunkie From Daily to Track Monster”
Would I require spacers to fit those Enkei wheels on a 2005 sti to clear brembos? And would I need to modify the fenders for a 245 or 255 or 265 tire?
