Watched video #58 last week and thought it was fascinating. The engine builder mentioned how a piston flexes and how they control the size of the port that expands the compression rings. Race part versus a production part.
Topic that got me the most was at 20:10 talking about front wheel toe and tie rod placement. Robbie says in the front youre always striving to have toe out. Is that because its a 4 wheel drive vehicle? I know some front wheel drive cars purposely have toe out, because under load it goes back to neutral. I would have guessed a sxs had toe in like a quad or truck on the highway.
