Complete Rear Upper Polyurethane Shock Mounting Kit For BMW E30 E36 E46 Z3 Z4

The metal plates on top of the E30, E36, E46,Z3,Z4 rear shock towers have a well-known weakness: the metal is prone to tearing over time, especially when subjected to strong impacts.
It is the best insurance for the shock mount to install the Complete Rear Upper Shock Mounting Kit to avoid repairing expensive shock mounts in the future!

Features:

• High Performance - Eliminates deflection of factory shock mounts under load and reduces the negative effects from rear shock damping, especially with improved suspension and additional shock valves. Helps to keep the rear shock absorber in the proper position for its proper operation. Also improves ride experience by eliminating rear end knocking caused by rubber wear in the original rear shock mount.
• 85A Polyurethane bushings with superior performance - Polyurethane has less compression variability, high stability, shock resistance, and aging resistance. It is superior to the common rubber in the market.
• Perfect fit - 10mm hole pitch.
• 3mm High Strength Steel - Sturdy and durable, efficient reinforcement, prevent tearing.
• Value for money - That old saying - "you get what you pay for" could not be more readily applied here!

Fitment Note:
We found that the factory E30 M3 had too much seam sealant near and around the top of the rear shock mounting area, causing the reinforcement plate to not lie completely flat.
Please modify the plates to accommodate the manufacturing tolerances of these specific models.


IMPORTANT:

The 10mm/12mm sizing refers to the inner diameter of the shock mount sleeve. The size of your shock dictates which size you need (OEM is 10mm; aftermarket shocks vary and must be measured). If you aren’t sure which size you need, measure the OD of the top threaded portion of the shock, or check with the manufacturer.

10mm (shock shaft diameter) fits standard shocks and some coilover systems such as for BMW OEM Shocks,For Bilstein PSS9/PSS10.For H&R Coilovers,For FK Coilovers,For Raceland,For ST Coilovers,For KW V1, V2, V3,For Koni Sport/Dinan and For All AST 4XXX/5XXX Series .
12mm fits racing coilovers such as for Tein（some), For MCS, for JRZ, For Ohlins and For TC Kline S/A or D/A. Does NOT fit convertible models.
