Update on S54 oil pan and subframe details: As for the subframe specs it is cut and reinforced with 1/8 plate, the cross member is 1.75x.095 DOM tubing, steering rack mounts are 3/16 steel. HD subframe adds 2 additional mounting points at the fire wall and is thru bolted to frame (Oil pan has to be shaved slightly on a corner to clear these) Sway bar mounts are a boxed in design that are wither thru bolted or welded just in front of the subframe to the frame rail. This takes additional stress of the subframe. Oil pan is modified using 3/16” thick 5052 aluminum. All pans are bolted down with a sealed gasket to a flat surface and pressure tested to ensure there are no pin holes or any chances there could be a oil leak. Oil capacity is approximately .75qt greater than factory. I will get better pictures soon. I didn’t have the time or space completely pull my drivetrain again. If you are willing to provide detailed pictures of install with the car up on a lift or anything like that Im sure I can work out some sort of credit back to you. If there are any detailed pics you want just let me know.
Parts I need from you
1. Oil Pan. Include one of the m6x100mm long rear oil pan bolts. (Needs to be installed before expansion tank.
2. Subframe. Complete or cut just outside of steering rack mounts.
3. Dipstick tube
4. Oil drain tube
5. Sway bar mount you will be using if different than oem.
Additional info needed:

2. Thru bolt or weld on sway bar mounts
