“Adding power makes you faster on the straights. Subtracting weight makes you faster everywhere”
-Sir Colin Chapman
Colin Chapman founded a small car company based around this philosophy. They made street and racing cars following this mantra, and most of the time it worked brilliantly and didn’t kill anyone. People (not necessarily the people who are running his company) still subscribe to his now legendary philosophy. Greg Valdez is one of those people.
Starting with an already modified 2005 STi, Greg did what Sir Chapman would approve of: he proceeded to rip heavy things out of it. All of the doors have been gutted. The glass windows in the rear doors have been replaced by acrylic, and the front windows are non existent. There is a, singular, Prodrive by Sparco racing seat (from his old race car) and a matching red Corbeau 5 point harness. A 353mm black suede Sparco steering wheel replaces the stock unit (and its pesky, heavy airbag), and a Splash short hub adapter and a WORKS Bell quick release make the wheel work. The interior is so spartan the controls for the center differential have been left hanging out next to the Kart Boy short throw shifter.
The car was already fairly modified when Greg bought it. The cage was already in there, the Stoptech ST60 big brake kit was already installed along with the Hawk DTC-70 pads in the front and the Pagid RS 14 pads in the rear. The APR extended wheel studs and Kics lug nuts were there too; however, the massive 18×10.5 Enkei RPF1’s and Pirelli race slicks were additions made by Greg. They fit under the Karlton fender flares rather nicely, and the flares accentuate the Cusco lip.
This car was known for it’s track ready suspension setup. A setup that never saw any real track time. The car has TEIN Super Racing coilovers at all 4 corners, with 16k spring rate springs in the front and 14k in the rear. Theres a GT Spec subframe brace, and a Carbing front strut tower bar and a tow hook up there too. The tow hook doesn’t work too well, so Greg added the pair in the front and another in the rear. There is also a mess of Cusco parts, including: a center brace, T brace, H brace, 22mm front AND rear sway bars, rear subframe brace, trailing arms and lateral links. Kartboy front and rear endlinks replace the OEM units. The roll center adjuster comes from Whiteline as does a racing version of their anti-lift kit. All of this does wonders, but is pushed aside when you notice the 30 POINT WRC SPEC ROLL CAGE. Let me say that again: A 30 POINT WRC SPEC ROLL CAGE. Serious really doesn’t begin to describe the cage. Most of the bushings have been replaced: Kart Boy shifter, transmission, and rear crossmember, TIC rear differential, and Beatrush propeller shaft bushings all occupy the places the old bushings.
The interior is non-existent, and the suspension is beyond serious. The motor has to be some crazy stroked out, big turbo monster right? Nope! Ladies and gentlemen, the very fast white Subaru is powered by what is essentially a COBB stage two tuned motor. It has a full turbo back Turbo XS exhaust, a COBB version 1 Accessport, a SPT short ram intake (with a very clever, homemade NACA duct feeding it), an APS equal length Ti header (that has been wrapped), a Koyo aluminum radiator and a 13 row Mocal oil cooler. This thing runs on 91 octane pump gas for crying out loud!
This combination of weight reduction (the car weighs just over 3000lbs with Greg in it, while a stock ’05 STi weighs just shy of 3300lbs WITHOUT a driver), heavy suspension modification and tuning (courtesy of the guys at Innovative Garage) and light power additions (that idiot kid who ALWAYS wants to race you in his STi? Stage 2 crew) have turned this “could be” track day terror into a car that laps the 2.2 mile East Course at Miller Motorsports Park in the mid 1:40’s. Less truly is more
