The Scion Tuner Challenge projects have been unveiled ahead of their debut at the SEMA show next week.

Scion's annual challenge invites tuners to apply $15,000 worth of modifications in a 90-day interval on a Scion for the SEMA show and this year rather than giving the cars to tuners, Scion decided to ask three media outlets to participate in the project: Super Street, Speedhunters and GT Channel.

First up, the FR-S by Super Street like all customized cars is based on the Release Series 1.0 but with a wider body, 18-inch wheels, six-piston front & four-piston rear Wilwood brakes as well as a KW clubsport coilover suspension and an Eibach rear camber kit. Inside it gets Recaro Sportster CS seats, six-point rollcage, quick-release steering wheel and uprated sound system. A lot of work has also been put in the engine which benefits among other from a Borla header, catback exhaust with quad tips and Wilwood master cylinder kit.

Second on the list is the FR-S by Speedhunters with a custom front splitter and rear diffuser as well as tinted Lexon taillights and an AeroJacket trunk. The cabin boasts bespoke leather trim, bucket seats, four-point rollcage, quick-release steering wheel hub and four-point harness. The 2.0-liter boxer engine has received a Cosworth supercharger kit as well as a three-inch single exit exhaust.

Last but not least, the Scion FR-S by GT Channel has TRD headlights, side fenders and side skirts, Avest rear wing and mirrors, along with a carbon hood, rear diffuser and trunk cover. There's a TRD steering wheel inside the cabin where the customized FR-S also has Recaro seats, Takata harnesses and a TRD shift knob. Other upgrades include KW Suspension Clubsport coilovers and a HKS GT supercharger kit for the engine which also gets a Ganador exhaust.

Aside from these three cars, Scion will also be showcasing a targa FR-S along with customized xB and tC models at the Specialty Equipment Market Association show which will take place between November 4 and 7 at the Las Vegas Convention Center.

Full specifications of all three cars can be found at the source links below.
