Anyone who has really built a car will tell you that it's easier said than done, especially when there is a deadline involved.

There’s something about deadlines that encourages the universe to throw “wrenches” your way. That’s exactly what happened with Seibon Carbon’s SEMA Subaru STI.

Before getting into the details on how the universe tried to conspire against our build, let’s talk about the build.

Snail Performance’s STI is in no way a trailer queen! This build enjoys plenty of track days and was built and tuned by Snail Performance. These guys work on GTRs, Porsches, and Subarus on a daily basis.

The goal for SEMA was simple: to revamp the STI while maintaining its functionality for the track. Believe it or not, SP drove the STI out from SEMA and straight to the track!

Introducing Carbon Roof Fin Spoiler

The first order of business was to wrap the STI with Intense Blue Avery wrap. This color was chosen for obvious reasons.

In terms of carbon fiber, the STI received the Seibon Carbon treatment: hood, trunk, front lip, side skirts, rear lip, and roof fin spoiler. SEMA 2015 was the first time the public was introduced to our CW-style hoodintegrated duckbill C-style trunkMB3 front lipMB side skirts, and MB rear lip. Also introduced at the show, the Beat Sonic/Seibon Carbon roof fin spoiler. The fin spoiler was a special collaboration piece with Beat Sonic and is only available through them.

The C-style trunk lid is not a style we usually offer for Subarus. This year we decided to make the STI’s trunk a little more aggressive. The feedback Seibon Carbon received was exceptional!

Also on the exterior, Rays/Volk Racing ZE40s in Matte Blue Gunmetal accompanied by Yokohama’s ADVAN Neova tires. This combination allows the STI to maintain driving control on and off the track.
On the interior, Razo/Carmate’s competition RP123 MT Super Grip pedal set, black 46g shift knob, and wide mirror.

Not everything was smooth sailing at SEMA. One of our show pieces was damaged while in transit to the show! Luckily, and with the help from the crew at Mothers Cleaning Supplies, we were able to restore the roof fin spoiler to its intended glory!
