H&R Street Performance Monotube Suspension Kit (E46 M3)

Introduction

The H&R Street Performance kit is a ready-to-install suspension for a multipurpose BMW E46 M3. The shortened H&R inverted monotube struts and rear shocks are paired with a set of springs much stiffer than most lowering springs. This kit offers ride height adjustment, on the strut in the front and at the stock spring location in the rear. They will come assembled, ready to install if ordered with the optional Vorshlag spherical adjustable camber/caster plates. Having this system pre-assembled by Vorshlag means it does not require a spring compressor to install. 

Key Features

• Monotube front struts that utilize 36mm dia. pistons and 40mm inverted shafts that maximize deflection resistance under hard cornering loads
• Front struts are shorter than the OEM length, for more bump travel at the lower ride height (from the matched lowering springs)
• Monotube rear shocks that utilize OEM rear upper shock mounts
  
• Nitrogen charged for exceptional fluid foaming resistance on track
• Valved for a comfortable street ride with the matched lowering springs, with improved track performance, lower cg, and (with camber plates) adjustable front alignment specs.
• No valving adjustment on the dampers - less to fiddle with!
  
• This system fits all of the E46 M3 coupe and cabriolet models.
• Four corner ride height adjustment, to get the stance where you want and also to set corner balance
• Great price for a complete damper/spring/camber plate suspension kit
  
• Front lowering from 1.2" to 2.3"
• Rear lowering from 0.75" to 1.50"

CAMBER PLATES and REAR MOUNTS : Turn the H&R Street Performance kit into a StreetPro kit by selecting the camber plates option. These optional spherical strut top mounts are the legendary Vorshlag adjustable camber-caster plates made for the E46 chassis. These include the proper Vorshlag upper spring perch to fit with the included springs and are pre-assembled onto the front struts with the springs in place. With the Vorshlag plates, you can quickly adjust front camber track side with a jack and hand tools. Our plates are built using over-sized 19mm ID spherical bearings, designed to withstand the rigors of street and track abuse. All components are powder coated, plated or anodized for maximum corrosion resistance and long life. This Street Performance kit comes with the proper selection of components to allow the Vorshlag camber plates to fit the strut and spring perfectly - and it's even pre-installed to the strut. It doesn't get any easier than this.
