    373 swap

    Ive decided to go with the 373s as opposed to my stock 273s on my auto-Z. What tires should I use to get the traction I'll need for these gears? Also, should I consider sub-frame connectors and / or a high stall? If so, which high stall should I use? Any help is appreciated.

    Yes subframes are a must for even a stock car. Higher stall is always a great idea on an auto car. You will see .5 second gains with a high stall as long as you hook. I am assuming since you have stock gearing that you have a stock rear so therefore I would run Nitto 555r drag radials as being about the stickiest tire you will want. You should see great results from it especially being a mostly stock car. If you dont want to go the drag radial route since thetires wear out MUCH faster then you may want to look into something along the lines of BFG KDWs
