Front Stabiliser Bar Mount Bush Kit 27 mm for BMW E46 M3 - Powerflex PFF5-4602-27

Transform the front-end response of your BMW E46 M3 with this uprated polyurethane mount bush pair from Powerflex. Designed for a 27 mm front bar, these precision-fit bushes replace ageing OE rubber to tighten steering, cut body movement and keep your geometry stable under load. Expect cleaner turn-in, better mid-corner support and improved confidence on B-roads and track days.

We run these bushes on our own builds and customer cars. Feedback is consistently positive, with drivers reporting a noticeable lift in chassis precision, reduced roll and more consistent tyre contact. Powerflex polyurethane resists oil, salt and heat, stays firm far longer than stock rubber and is backed by the Powerflex Lifetime Warranty.

Why upgrade to polyurethane

• Direct-fit 27 mm front bar mount bushes for E46 M3 front axle
• Stiffer compound controls unwanted compliance and maintains alignment under load
• Sharper steering feel, flatter cornering, improved braking stability
• Helps reduce uneven tyre wear by keeping the front end planted
• Durable, corrosion resistant and long lasting compared to OEM rubber
• Perfect for fast road, track use and performance-focused builds
• Covered by the Powerflex Lifetime Warranty
