Default E36 subframe



Hey guys I’m the new and proud owner of my first M3 and need some input please.

I had a inspection done which pointed out an issue with the subframe arms for the engine mounts. The mounts had probably worn out and flogged the arms causing cracks. The PO had the mounts replaced and the repairer did some spot wields across the cracks. Not a tidy nor permanent solution.

Question is should I pull the subframe and have repaired properly or should/can I use a subframe off a standard e36 subframe with a m50/m52 engine?

Same subframe. Add front subframe reinforcements at motor mount mounting points. Cheap and readily available. Also do RTA pockets.

Check out garagistic if you want something ready-made. They sell nice powdercoated subframes with the reinforcements already welded in. You pay for it, but they're still reasonable IMO.

Or, source any used and intact/unrusted E36 front subframe from wherever and get the welding done yourself.

Unfortunately shipping alone to NZ would double the price.

Reinforcement plates are cheap though and will go this route.

Thanks all for your input

Huh, must be the white balance. Looks a lot more blue than normal.

So does the ROW M3 have the same subframe as a regular e36 6 cylinder? Looks like a 3.0 L car

Hi from NZ!

"Subframe arms"? Do you mean the subframe cross member (under the engine mounts) or the engine support brackets (that sit on top of the engine mounts)?

The cross member doesn't have arms... but if there are cracks on the cross member where the engine mounts bolt up you can simply weld in reinforcement plates, no need to replace the whole thing.

Engine support brackets are unique to the engine and I was going to say the cross member was the same across all e36's but according to RealOEM the M3 part is unique also... I'm not sure what the differences are.
