Revo Front Brake Disc Upgrade Kit Audi TTRS (8S) – RA551B200400
The Audi TTRS comes with a fairly substantial 8-pot brake setup straight from the factory. Whilst the stock calliper works very well the same can’t be said for the discs or the factory specification pads that seem to perform best at lower temperatures or very light road use. The factory 370mm ‘wavy’ discs certainly look the part but the design flaw is that both discs are identical; when fitted, the cooling vanes in the right-hand disc face the wrong direction and do not offer any cooling benefit. The excessive heat this generates combined with the factory pad compound causes big issues with braking efficiency and longevity of the disc and pads.
The Revo disc upgrade is designed to directly replace the stock discs and comes complete and ready to fit with left and right-handed, directional 380mm two-piece floating discs. Saving 1.2 Kg each side the disc not only weighs less than the OEM part but also features much larger, more efficient cooling veins individually designed for each side of the vehicle to ensure even braking performance, pad wear and cooling capability. This is a premium upgrade that should have come from the factory. As the Revo discs dissipate heat much more efficiently the factory pad compound works much better in real-world conditions, only when you’re using the vehicle on the track would we recommend considering a different pad altogether.
Key Features
- Left & right handed discs
- + 5% braking surface
- Two piece floating design
- + 10mm larger disc
- Larger more efficient cooling vanes
Heat Management
Heat is an unavoidable by-product of friction. Managing this heat efficiently is extremely important in order to avoid it transferring to the pads, caliper and fluid. The OEM RS3 discs are manufactured as a single part, pumping air in different directions on each side of the vehicle. This causes varying levels of cooling efficiency and temperatures leading to judder and brake fade.
Revo Discs
Revo discs are manufactured by Alcon and utilise over thirty years of motorsport expertise in their design and manufacture. Internal vanes are used to draw air through the centre of the disc outward, allowing the heat to transfer as it passes. The rotation of the discs and vanes play an important role in brake cooling as it acts like a pump to move air and unlike the OEM brake discs, the Revo upgrade consists of a right and left-hand disc to optimise cooling and ensure consistent stopping power for your vehicle.
Two Piece Floating Design
Utilising a two-piece floating design allows the disc and hat to expand radially and axially as they absorb heat generated from use, avoiding the most common cause of warping and cracking seen in single-piece rotors. Due to the efficiency of this design, Revo discs last considerably longer than factory discs. The friction surface features crescent groves that increase bite and remove debris from the pad surface giving the perfect balance between brake feel and longevity while minimizing the pedal pulsations normally associated with straight-slotted rotors or cracking issues common with cross-drilled rotors.

In the words of the Vehicle Standards Agency (VCA), type approval provides "confirmation that production and samples of a design will meet specified performance standards".
For emissions components this encompasses noise, emissions and balanced back pressure, which have a strong influence on maintaining engine performance (power), and fuel efficiency. Type approval ensures that an aftermarket component will reach, or exceed the performance standard of the corresponding OE part.
Type-approval then, is a certain guarantee that an end user will receive a product of OE equivalent performance attributes.
Products on the Progressive Parts website that meet this approval will be clearly marked or labelled EC or ECE approved.
