Ohlins E9X M3 TTX Pro Coilover System

The Öhlins TTX Pro Coilover System for the BMW E9X M3 is a race-derived suspension package designed for drivers who want the highest level of damper technology on the proven E9X platform. Built around Öhlins' TTX — Twin Tube eXtreme — technology and pairing a TTX46 front damper with a TTX36 rear unit, the kit brings over 40 years of Öhlins' competition experience from Formula 1, IndyCar, and MotoGP into a purpose-built coilover system for the E90 sedan and E92/E93 coupe and convertible. TTX technology uses a twin-tube damper architecture where an inner working tube and outer reserve tube regulate fluid flow with high precision. The TTX46 front units handle the McPherson strut geometry's compression and rebound demands with the resolution needed for track driving, while the TTX36 rear units provide precise damping control through the E9X's multilink rear suspension. Independent compression and rebound adjusters on each damper allow separate tuning of each phase — a level of setup flexibility that a single-adjuster system cannot match. Öhlins' temperature-compensating design maintains consistent damping output as fluid temperatures rise during sustained track use. Recommended adjuster settings range from 10–12 clicks for aggressive track use to 15 clicks for street driving, with fine adjustments made in combination between front and rear to balance the chassis. The kit targets a ride height reduction of approximately 10mm below standard, with an adjustment range of +5mm to –20mm. Ride height is adjusted independently of spring preload so that height changes do not alter spring characteristics or reduce usable suspension travel.
