Subframe reinforcement

rstoughy · 15-07-2019, 10:53 AM

Ok folks,
With the CSL currently going under a restoration project I am contemplating fitting the reinforcement plates to the subframe mounts.

The car had a new panel fitted by BMW Elms and had the foam / Resin injection at that time. Upon dropping the sub frame the mounting points look perfect.

Now is it as good idea to fit these plates now while it is all stripped?
What will happen to the foam / Resin with the welding?
Should I leave as is and fit Polly bushing to give a flat surface for the subframe to mate to the panel?

Just don't know, I was tempted to just leave it all OEM but have been advised otherwise.
Anyone done anything similar?
Be interested to hear from anyone that has done the plates post foam / Resin injection.

Ta.
