I'm gathering parts for my tranny rebuild and need to decide on a 3.90 or 4.25 r&p. Most of my autocross experiences have been all second gear courses. I want to stay closer to the sweet spot without being a moron and forcing myself to shift into third because I've gone too low on the r&p. It comes down to not wanting to get the 3.90 and seeing little to no results or getting the 4.25 and shifting into third and just moving my no torque problem up one gear for 500 bucks.The trans will get a lightened/balanced flywheel, quaiffe, new r&p and fourth gear cog if necessary.
