Andy Kuo’s 2007 WRX: ‘Function = Form’

For someone who has been in the car scene for a while, it is beyond refreshing to see a person’s love for their car and a real and genuine love for the scene. Andy Kuo has owned and been building his 2007 Subaru Impreza WRX for over 11 years.

Andy’s mentality is function equals form, and his goal was to build a car that exemplified that symphonic harmony. Every part of the car serves to address a specific functional, or practical, purpose to meet his ideology.

Over the last decade, Andy has created a raw, time-attack and track-oriented daily driver that corners like hell, pulls hard, breaks necks and sounds utterly badass with the GrimmSpeed 44mm External Wastegate screaming under boost below the car. It certainly has the power, performance, and style we love.

Under the hood, Andy has kept things simple, yet efficient. His Stage 2 EJ255 is YimiSport Protuned putting down 302 whp and 324 tq at a conservative 17 PSI. A ported and polished VF39 is fed cold air from a ported and polished STi Top Mount Intercooler and scoop splitter. The Walbro 255cc fuel pump makes sure the car doesn’t get too thirsty. The exhaust is made up of a PDE Catless Bellmouth downpipe, and a Grimspeed 44mm External Wastegate Uppipe with dump tube. These are mated to an STi Genome Axelback to accentuate that Boxer rumble.

The Rally and JDM influence are evident behind the wheel with the myriad rare Prodrive pieces bolted on. From the Recaro Speed bucket seat, a rare JDM version 8 Prodrive STi gauge cluster is seen, complimented by an equally rare JDM STi 5-Speed shift knob. Wrapping around the interior is a full Cusco 6-point roll cage, and a Takata Racing harness secures the driver during heavy cornering.

 

Invisible but equally important, are all the suspension and chassis upgrades that help stiffen up the car. A beefy Cusco 25mm rear sway bar reduces understeer and sharpens turn-in response while Cusco bushings eliminate all the factory slop of the softer rubber bushings. The Cusco front power brace and rear subframe brace stiffen things up even more to make the car handle like it’s on rails.

The car sits on a set of BC Racing BR coilovers with gold 18×8.5 +48 Advan RS wheels. To fit the 235/40/80 Nitto NT05 rubber, front and rear fenders were trimmed and rolled, along with the addition of Cusco rear camber plates and Eibach rear camber bolts. The ICHIBA 25mm front and 3mm rear spacers push the wheels out to fill out the fenders, even more, giving the WRX an aggressive stance.

Other exterior highlights include a Chargespeed front lip, Chargespeed Bottomline side skirt extensions and the awesomely aero Chargespeed carbon fiber mirrors. At the back of the car is an SYMS spoiler adding downforce, Voltex carbon fiber rear diffuser, and a subtle Ureshi Industries window spoiler.

All around the car are subtle nuances that only a true Suby enthusiast would notice, such as the STi shifter trim, STi floormats, STi door decals and Type RA-R Pignose trim on the nose of the car.

“The car, as it currently sits, has been built strictly for my own personal gratification; not for any exposure, hype, fads or conformity that all too often undermines the community,” Andy said.

His ultimate goal is to reach a point where he can step back and be genuinely content with how the car sits in all respects. According to Andy, he’s nearing that point, and in the time he’s owned the vehicle he’s modified it in ways he could never have foreseen and is already far beyond satisfied with how it sits; not an easy thing to do.
