Want to give your 992-generation Porsche 911 Carrera 4S a dramatic makeover? Well, German tuner Keyvany has you covered with this new "GTR" kit.

The package for the Zuffenhausen-based firm's sportscar features new carbon-fibre panels and an increase in power.

The company has added a new engine cover, wing, side skirts, bonnet, front bumper attachments, front lip and rear bumper, all fashioned from carbon. Additional bits include side-mirror housings and sill guards along with Keyvany badging, fore and aft. Three 21-inch front and 22-inch rear forged alloy wheel designs are furthermore available.

Inside, changes are also fairly comprehensive, and include a carbon-fibre and partial leather steering wheel, aluminium pedals and branded carpets. In addition, the entire cabin has been reupholstered in premium leather.

Keyvany says it has upped the 911 4S’s twin-turbo 3,0-litre flat-six’s standard peak outputs of 331 kW and 530 N.m of torque to 441 kW and 700 N.m. The package includes a new exhaust system with a catalytic converter delete.
