What made you decide to modify your car?

From day 1, I knew exactly what my plans were for the new model STI. To have a quick street car, but mainly, to have a quick track weapon, while still being able to maintain both aspects.

Whats the next stage with your car?

Car safety is my next priority, considering a racing seat, possibly a roll cage system. Anything that will help me improve my lap times.

Do you attend any track days or other racing events? If so how have you done?

I have attended multiple racing events in this cars lifetime. I have competed at; Eastern Creek, Wakefield Park, Phillip Island, Lakeside, Calder Park in club level SuperSprint. I have also put down a 11.8sec pass at Eastern Creek Drags in the early stages of this cars build.

Whats your favourite part about the car?

There are so many things to love about this car, if I was to choose one it would have to be the cars performance on the track. I have so much more to learn to get the full potential out of this car, but with what I can do now, it just amazes me.

What would be your advice for people getting wanting to modify their Subaru?

What is the main reason for modifying your car? Track? Street? Show? Once you have determined that, plan for what you would like to modify. Nothing is worse if 2 months down the track you replace a component because you didn’t do your research, or you weren’t sure what you wanted to achieve from your car. Take the time to plan your modifications, do your research and you will come out on top.
