I'm with ya Van.

We've always run a t400. Bracket racing we launch in 2nd gear, shifting into high right at the 330' cone. Pro tree, leave in 1st.
I like a tall gear also but I like a shorter tire. We're using M/T's 29.5x10.5x15 w/stiff sidewalls on a 12' rim with 5 1/2 lbs. air

Last race I added 1 pound to each tire for our first practice pass. Track is normally at it's worst, first time run. Much like the very late rounds. So wanting to check how close to the edge we were I added the air and moved her to the outside edge of the groove that was forming.
Car spun, taking her out to the wall at the hit. She stayed init way to long not being a final. But on the video it's amazing how little rear tire roll there was when she got out of it, and the car swung back around when straightening up.

Short stiff sidewalls have less movement in them on the hit. Less is more when trying to be consistent for us. Just add more gear right
