Dirt track setup help

[Mega3181]

I run an s14 at the local dirt track oval racing. My question is should I weld my diff? Currently has a lsd from factory but in trying to get some more traction to help get the car around the corners.

Also any other set up tips you guys are running.

I'm going to switch the gearing to 4.6. Still messing with tires. And will do a 240/232 cam set up to shoot for more mid range power.

Cars a beast but not winning yet, key to winning is getting around the corner, I can out run everyone on the straights
