Good thing you got the master cylinder brace transferred over. When I first learned about that I was a little shocked at how much it moved. That has to be one of the first mods for all the people that buy these haha.
i wish i transferred it. it's all new parts going on here haha i had the mod coverage on the old car, so i let most of the stuff go with it so i could get a little more back. i'm going to get all the same parts though the only parts sitting around are oem frs ones...which are now acquiring duplicates the rpf1s will be used again though, that's about it.
i did like the master cylinder brace on my frs, so i bought one for this car almost immediately haha. for daily driving there isn't much of an issue with movement, it's mostly under hard braking. i was surprised too when i first saw it, that's when i bought the brace i had on the frs haha.
