AUDI has put the TT and R8 on a high-fibre diet. What kind of fibre? Carbonfibre – and lots of it.

Available under the Audi Sport Performance Parts moniker, a range of go-faster upgrades for both cars will be available through Audi dealers, and can be retrofitted to already purchased cars. It’s not just carbon bolt-ons either – there are some genuine track-spec mechanical bits to enjoy as well.

Among the carbonfibre options are two- and three-way adjustable coilover suspension packages, as well as uprated brake pads for both the standard fit steel brakes and optional carbon-ceramics.

Also on Audi Sport’s tuning menu are upgraded steel front brake discs for the TT RS, as well as various brake cooling kits for all TT models. CNC-machined 20-inch wheels are available for both the TT and R8, and reduce overall mass by up to 7.2kg on the TT and up to 8kg on the R8. For the TT they wear 255/30-section tyres all around, while the R8 is shod with 245/30 rubber up front, and 305/30 tyres at the rear.

The headline act though is the carbon-centric aero kits, which were wind-tunnel developed in-house and bring some track-style flavour to Audi’s sports coupes.

On the inside, Alcantara-clad steering wheels with a red strip at the 12-o’clock position strengthen the racecar theme for both TT and R8, and can be paired with carbonfibre shift paddles. The wildest – and most visible – feature by far, however, is the monstrous carbon rear strut brace for the TT, which replaces the rear seats entirely (saving 20kg in the process) and ties the rear suspension towers together to improve torsional rigidity. If you’ve unsuccessfully tried to use the TT’s rear seats, you’ll know that you’re better off turfing them for this slick piece of carbon architecture.

“Our wealth of experience garnered over many years of building sports cars is incorporated into every component we offer. Along with our expertise from motor racing, which is still the best testbed for volume production.”

While currently only available for the TT and R8, other Audi models will soon be added to Audi Sport’s performance parts catalogue.
