Hello!
This listing is for a complete Z3 SUBFRAME REINFORCEMENT SERVICE, performed at our shop in McKinney, Texas. This service modifies the original chassis and installs a "Randy Forbes" style (dual mount) reinforcement kit into all Z3 and Z3M chassis variants.WHY:It has been observed that all E36 Z3 variants, especially the higher performance Z3M roadsters and coupes tend to suffer from distressed sheet metal and trunk floor failures in the trunk areas and above the stressed member which supports the differential. Indications of failure may include visible cracks, popped spot welds, and delamination around the trunk floor panels. Not all damage is visible however, but the driver may still notice creaking, popping, or looseness in the rear of the car.The factory chassis supports the rear differential mounting via ONE connection to the trunk floor. The Randy Forbes method resolves the inherent weaknesses in the design with stronger metal plates, replacing the factory mounting AND reinforcing the connection points in the trunk floor with a beam and plate design between the frame rails. The OE style "single" mounting point is offered for a robust and long lived solution recommended for owners not wanting to drastically alter the vehicle. This reinforcement method also provides for the option to add a second mount ear, enabling the upgrade to an E36 M3 style "dual ear" differential cover (pictured above). This method significantly increases rigidity of the differential mount and trunk floor, and is recommended for Z3M models and performance driven Z3.This listing is priced for the "dual ear" option and includes the parts and labor required for the conversion. The job can be customized if the single mount version is desired.
**THIS IS PRICED AS A PREVENTATIVE JOB PACKAGE. PLEASE NOTE THAT ADDITIONAL DAMAGE, BROKEN SPOT WELDS, SEPARATED SHEET METAL, ETC WILL RESULT IN ADDITIONAL LABOR AND ADJUSTMENT OF THE FINAL ESTIMATE AFTER YOUR VEHICLE HAS BEEN ASSESSED.***
This reinforcement service is relatively involved and requires disassembly of the rear suspension and trunk for roadsters, and the rear interior of coupes, cutting away of factory body sheet metal and trunk floor. During this job we perform disassembly carefully and document any trim components, clips, or hardware that we find damaged or missing to be replaced on reassembly (added to total costs as needed). The interior is protected with special weld paper to avoid damage to interior parts during the cutting and welding. All welding is performed by one of our fabrications experts via gas shielded MIG in a way that minimizes excessive heat transfer into the body. Weld-through primer, cavity wax, seam sealer and factory color e-coat are utilized strategically to provide the longest lasting results with no chances of new rust formation. Our process is performed in a way that best mimics factory type processes and appearances for a seamless job. The body colors in the coupe trunks are matched as closely as possible. For dual mount differential case conversions, the differential is disassembled, fully cleaned in our aqueous and ultrasonic part washers, aluminum components vapor honed as needed for as-new appearance. The speed sensor ring is removed and modified on our lathe to the correct new diameter and a new speed sensor included. Finally, it is reassembled with new seals, o-rings, hardware, and gear oil, then reinstalled in the vehicle. Vehicles are road tested afterward to ensure a satisfactory job. As each job requirement is slightly different, we consult with each client to perform the job to their spec.
