Characteristically if a person where to shift just a little before he brakes a Daytona into turn one, especially one, but really any other turn as well he would be using the engine as a brake commonly referred to as "back holeing". The boxer style motor is very vunerable to this situation. Carrillo rods Tia rods all help the situation as well as more bearing clearance but will not prevent it totally as a Carrillo rod and a Porscche rod are essentially made of 4340and the Carrillo is a little more refined utilizing a SPS bolt which is in mass more robust. the Tia rods probably eleminate the issue as they sling a signifficantly reduced mass over TDC during the exhaust stroke with no load on the piston, which is essentially what kills the rod bolts and even a Carrillo won't take the deformation of the big end unless there is more bearing clearance built in to the package.
