BMW Z4 E89 35i and 35is Sports Suspension Upgrade - Part Number 46-181275

Give your 2009 to 2016 BMW Z4 E89 a genuine fast road transformation with this complete shock and spring package. The kit combines Bilstein B8 sport shock absorbers with Eibach progressive-rate springs to deliver crisp turn-in, flatter cornering and a purposeful ride height drop, while maintaining day-to-day comfort for UK roads. If you want sharper handling without a crashy ride, this is the uprated suspension package that Z4 enthusiasts trust.

We have installed this setup in-house and the feedback from owners has been consistently excellent. Expect a more planted roadster with tighter body control, improved high-speed stability and confidence-inspiring steering feel. It looks right, it drives better and it lasts.
