That additional suction stage oiling system change is pretty slick! Got any pics of the baffled oil pan? Or will that be in a future article.

Just glad you guys got the oil control under control. Can't wait to see what you do in Tuner with this thing!

I too am a big fan of removing squishy rubber bushings in BMW suspension. Especially 30 year old versions that are absolutely SMOKED.

That said, after a chat with the XAutomotive crew, they supposedly have a full auto mode they say is really good on track. I'm going to load it up next time we test and give it a try. I'm definitely curious.
