Made in the USA These are the best rear shock mounts that we have found for the E30, E36, E46, Z3 & E85 Z4! Featuring CNC-machined billet aluminum mounting base with a replaceable urethane bushing (replacement bushings are just $15 and are changed in minutes!). These mounts are excellent for either street or track because of their low NVH (noise, vibration, and harshness). Plus, the superior design will far outlast the life of stock mounts - maybe even the car itself. You'll never think twice about your shock mounts again! These shock mounts are a direct replacement of the stock mounts so they fit all shocks with the BMW-standard 10mm shock shaft, including all factory and OEM shocks (Boge, Sachs, etc), H&R coil overs, Bilstein shocks and PSS, PSS9, PSS10 coil overs (except the B16 Ride Control Kit). This is sold as a package with new shock mount gaskets, washers, and Nyloc nuts.

Must re-use factory cupped washers!

A strut tower brace adds additional reinforcement to the front strut towers, tying them together for extra rigidity. This makes the whole structure stronger with less chassis flex. Handling and steering feel are improved with better turn-in and input with no downsides. The Dinan strut tower brace is a very high quality aluminum brace with precision machined ends that match the contours of the strut tower. Other braces simply sit on top which reduces their effectiveness. This is definitely one of the stronger strut brace designs on the market. The center bar is polished aluminum with carbon fiber inlays - an unmistakable sign of precise engineering when you open the hood.

For over 35 years, Dinan has been America's premier tuning company, pioneering advancements in BMW modification while retaining a focus on balanced performance that preserves the original character and driving feel that a BMW offers. When you install a Dinan part on your car, know that it's not only carefully developed and tested, but that Dinan stands behind it with a four year, 50,000-mile warranty. Dinan believes so fully in their “total package” approach that once your car has been fitted with enough of their parts, they celebrate your conversion from stock to Dinan with an exclusive trunk badge, displayed proudly by BMW enthusiasts everywhere. This part is worth 2 points towards your Dinan badge.

Dinan Performance Springs are matched to your BMW's chassis and suspension components to deliver better handling and looks without sacrificing ride quality. Dinan BMW springs are carefully engineered to work within your car's suspension travel and to improve suspension geometry. Spring rates are slightly stiffer than stock and dialed in to reduce bodyroll. A stiffer suspension makes the car more fun to drive and the lower ride height improves the looks by reducing wheel-fender gap.

Dinan spring specs -

  • F: -5/8" (16mm)
  • R: -1/4" (6mm)

Fitment note: Dinan only recommends these springs be used with their custom-valved Koni shocks. While not explicitly required, less than favorable ride quality and handling may result without them.

This Dinan suspension system system consists of a set of performance tuned springs and carefully matched Koni adjustable front strut assemblies and rear shocks.
