Our OEM+ Performance Software is simply the most effective modification you can make to a modern turbocharged engine.
RacingLine offers separate stages of performance from Stage 1 to Stage 3 - plus Stage 1+ for the later GPF-equipped cars.
And remember, it's only with OEM+ that you get FREE upgrades up to the next stage whenever you're ready to continue on your tuning journey.
Carbon Air Intake.
In all of our B9-platform R&D work, it has become very clear that whilst the laser-welded body is very stiff and well reinforced, handling will always benefit from a sharper, stiffer bodyshell.
So, our beautiful B9 Billet Body Brace for all A5, S5, RS5 tightens up the weakest point on the car between the top suspension mounts, replacing the flimsy factory version.
All with no drilling or cutting.
Carbon Air Intake.
Doesn't your pride and joy deserve better than the cheap plastic parts in the engine bay and around the car?
We think so too, so we've introduced our beautiful billet aluminium replacement caps and housings for B9 A5/S5/RS5. Hand polished, then anodised in deep midnight black to look good, and keep your car functioning perfectly for years to come.
