Volkswagen Fox by RDX Racedesign

The Volkswagen Fox may not be on the top of your list for an aerodynamic make-over, but RDX Racedesign caters for a niche market of Fox fans. RDX designed a new front spoiler with integrated grille, side sills and a new rear apron to give the rather conservative small car a brand new look.

The RDX badgeless front end lends the Fox with a Golf GTI-look while the new Audi S6 daylight running lights are an optional extra. The side sills and rear diffuser match perfectly and RDX has left the rear bumper without tailpipe cut-outs, leaving that to the discretion of their customers.

The body kit is fully TÜV certified and approved and costs just over Euro 615.

Mercedes SLR Mclaren 740hp by Renntech

When we first heard of the Mercedes SLR Mclaren 722, we all licked our lips at the prospect of a 722 horsepower engine, but when the final figure of 650hp was released it left a sour taste in our mouth. Renntech soon put that sweet taste back with their own tuning package which boosted the supercar's power up to where it should be at 722 horses, and now by popular demand the tuning house has pumped yet more ponies out of the 5.4-liter supercharged engine bringing total power up to 740hp

For the upgraded tuning package Renntech have re-worked the ECU software and added a less restrictive motorsports-style exhaust system to get the extra ponies to the new Renntech Signature 10-spoke, 3 piece performance wheels.

For an extra bit of added spice the tuner has also provided a nice little video in which you can hear the engine.
