Way Motor Works has been making our famous WMW baffled oil pans for about 9 years now, but we just updated the design. The updates we did reduced the number of parts which also reduced cost passing the savings onto the customer.
The aluminum baffles are all laser cut out of one solid piece. Then the 3 trap doors are mounted on the baffle using top notch aircraft hardware to keep the oil around the sump. The entire system is welded to a brand new oil pan so there is no way it can come loose or get bent around the sump. Others are just a wall to slow the oil rather than trap it around the sump.
So if you are tracking your MINI, or just want to be extra safe and prevent any oil starvation this is the best option you can get.
