XYZ Racing Street Advanced Coilovers — Audi TT 8S 4WD φ55 (Cancellation Kit for Electronic Damping) 2015-2026

The Audi TT 8S’s transverse four-cylinder sits ahead of the front axle, and even with quattro splitting drive across all four corners, the nose still carries more of the car’s mass than the rear wants to manage through a quick direction change. On cars specced with Audi’s electronic Magnetic Ride dampers from the factory, that weight bias is being smoothed over in real time by a control module guessing at damping rates rather than a driver setting them directly.

This is the cancellation-kit variant built specifically for that scenario: it defeats the OEM electronic damper control so the module stops hunting for a magnetic damper that physically isn’t there anymore, and hands full authority over to the coilover’s own valving. Street Advanced is XYZ Racing’s road-and-track spec for the TT 8S – firm enough to sharpen turn-in on a nose-heavy quattro chassis, still liveable enough for the daily commute.

What this coilover kit does for your 2015-2026 Audi TT 8S 4WD φ55 (Cancellation Kit for Electronic Damping)

With the factory Magnetic Ride system cancelled out, damping response stops being an algorithm’s best guess and becomes something you can feel change under your hand. The 720-way damping adjustment gives you a genuinely useful spread between a setting soft enough for cracked B-roads and one firm enough to control the 8S’s nose diving under trail-braking into a hairpin. Ride height is adjustable independently of that damping curve, so you can drop the quattro’s centre of gravity for track days without giving up the compression travel a daily-driven TT still needs over speed bumps and potholes. Because the φ55 shock body is doing the mechanical work the OEM dampers used to fake electronically, the front end’s transitions into and out of corners get more predictable, not just stiffer.

About the Street Advanced coilover

Street Advanced is one of XYZ Racing’s longest-running products, refined over several years of development and proven on cars running in motorsport events worldwide before it ever reached a road car. It’s positioned deliberately between XYZ’s comfort-first street kits and the fully track-focused ranges: built for drivers who use the same car for a normal commute and an occasional track day, not one or the other. The 720-way damping adjustment sits at the centre of that brief, giving a far finer resolution of control than a basic threaded coilover, and letting an owner move from a compliant road setting to a noticeably firmer track setting on the same shock. For a platform like the TT 8S, where quattro sends torque to the rear axle under load and load transfer happens fast, that adjustment range matters more than a fixed-rate spring-and-damper package would.

Fitment for the Audi TT 8S 4WD (2015-2026)

Fits the Audi TT 8S 4WD quattro, chassis code AU47-C, across the 2015-2026 model years. This is the φ55 (55mm shock body) cancellation-kit configuration specifically for TT 8S quattro cars built with Audi’s factory electronic damping – the kit disables that system so the coilover’s mechanical damping is the only damping input the car sees.
