Accusump mounting

+1... once proven to work and not leak, you'll very rarely need to get in there. Some rivet nuts holding down the sheet would probably even be fine, or dzus if you really wanna be fancy.

Are there oil pan baffling options? It sounds like you may have already made your decision... but do you actually have starvation issues? if your car is NA, stock power, and your not running a cheaty tire/making a ton of grip, you may be fine with just an oil pan baffle. Unpopular opinion, but stock cars running a harder tire, I prefer avoiding adding extra failure points to the oiling system (accusumps/coolers). One broken line or component and you've littered the track with oil and concurrently damaged an engine. A good modern oil can tolerate the elevated temperature and abuse, and I think most of our cars are slow enough in the corners to not oil starve with a baffle (so far our miata and 735i we've been able to avoid starving no baffle+overfilling oil 1/2qt). My TA miata will starve for a split second under hard braking or sustained cornering, but pulls more G's. I don't know how close the margin is for the 2 Lemons cars, but so far there's about 150 hours on the miata engine, and about 70 hours on the BMW engine.. both junkyard engines w/o a baffle, cooler or accusump, just decent synthetic oil.

  Sadly we have broken 2 bottom ends due to oil starvation. One at a track day and one at a race. We already have a Moroso baffled pan, so it’s time for the next step.

Maybe I've just been insanely lucky, or blissfully ignorant. All of our cars have a low oil pressure buzzer/light that goes off at sub-7PSI. We've had that go off for the time attack Prelude and Miata, which run stickier tires and was fixed with a baffle and/or accusump. The two Lemons cars (miata and 735i), running an RS4 (slower) compound hasn't been able to set off the buzzer. The miata has been corner balanced, and aligned per years of pyrometer data, so it corners decent, and still hasn't set off the buzzer... for all we know it could be dipping to 8-10PSI, but we're also typically not WOT until we've exited the corner. We could have been playing with fire for years but it seems fine... miatas have a factory shitty baffle, but better than nothing. I don't think BMW factored in oil sloshing when engineering a 735i... but I'm not a BMW guy so I don't know, I just bought it because it was cheap, but it hasn't set off the buzzer with RS-RR's and a decent alignment. Was the oil topped off when the failure occurred? I'm sure we'd see our buzzer go off if we were a quart of two low on oil but we always keep it full to slightly overfilled and it's been okay. But I guess YMMV... we are running a BMW and a miata so maybe I'm not the best for advice here.

By cheaty tires I mean any super 200 tires... RT660, A052, RE71RS, etc. We run RS4s and they're quick but they're not making 100TW or (sometimes) hoosier levels of grip like the super 200 category.

Interesting the moroso pan didn't do the job. I have a door/gated style baffle I DIY'd for the time attack miata and oil pressure is solid even with hoosiers.
