05+ g35 coupe master cylinder brace
 

No price listed.

I've been temped to buy one and try modifying it to make it work with a strut tower brace...

That's an amazing part for anyone who is on the fence about buying one, there is a LOT of firewall flex on the G and this fixes nearly all of that problem.

i wanted to install it so bad but it wouldn’t work with my ARC strut bar and I want removing it :52:

I was thinking of milling the brace a little thinner where it goes over the top of the strut brace bracket then drilling holes in the master cylinder bracket and tapping matching threads in the strut tower brace bracket so it would bolt the brackets together instead of using the strut bolts. You might try it out is you have access to something to cut/mod that master cylinder brace.
