Key reasons enthusiasts choose this Dinan suspension for E90 and E92 335i

• Dinan Quiet Design camber plates for one of the quietest adjustable setups available on the E9X chassis.
• Suspension packers included to set progressive bump stop clearance like a proper race-style setup.
• Front camber easily set via slotted mounts from approximately -1.2 to -3.2 degrees for road, fast road or track use.
• Top mounts machined from 6061-T6 aluminium with heavy-duty rubber and barrel shaped Delran internals for durability and low NVH compared to spherical mounts.
• Accepts 2.50 inch I.D. racing springs for future spring rate changes and further tuning.

Real-world results

On-car damping adjustment makes it simple to tailor the ride from daily-friendly to track-ready. Turn-in is crisper, body control is tighter and mid-corner stability improves. Thanks to progressive bumpstops and clever spring geometry, the car retains composure over rough surfaces even at lower ride heights. We run this setup on our own builds and customer feedback has been consistently positive for balance, confidence and comfort.

Ideal for street, fast road and track days

Whether you are chasing better traction, a lower centre of gravity, cleaner fitment with your wheels or a more precise alignment range, this Dinan package delivers. It is a proven upgrade for N54 and N55 powered 335i models seeking a serious suspension refresh with proper adjustability.
