We have always run a mini-spool in our factory stock on a 7" DOT tire rule. Been bench talking about stagger, tire slippage (inner VS outer) in the corner vs straightaway, Coupled with our limited tire tread width and horsepower limitations. Is it possible a One legger or limited slip set up may do better? A track promoter for an out of town open show made a statement to me that no one had ever won his hobby class open show with a locked rear end. Just got me thinkin........Crazy?

Maybe its just becasue I'm a skeptic, but it sounds to me like this guy don't want any out-of-towners to show up and take his money! I would definately lock the rear end. You may do allright with some sort of locker type rear end, but you won't go anywhere with a one legger. JMO.

We are talking dirt track right? I believe there would be some advantage to it on asphalt with a low horsepower hobby stock type class. The idea being, the car will roll through the corners alot easier and actually be a little more stable. I guess the same thing could apply to dirt, but I would still lock it.....my $.02

I agree, I wouldnt run without the spool. My thought was runnin' towards tire slippage in the corner- inside tire out runnin, outside tire, etc. The whole idea started with a conversation about stagger and how we use it to track tune the car. When you raise or lower your stagger amount you change that relationship of rear "tire slippage" with the track. The theory that if A tire has a certain amount of grip, and you throw away or scrubb off a percentage of that grip in the corner because your rear tires are fighting each other, Your giving up cornering speed, and stability. I still wouldnt unlock my rear, but what about a way to find the best stagger amount for my track? Radius, Banking, Etc. Anybody ever done anything like this?

Thanks True Blue. Hey Outlaw, Detroit locker? Are you talking about an air locker type? Or is that a Centrifigal locker like A Gold Track? I've even seen Napa selling A centrifigal called Powertraxx. I've never heard of, and wouldn't even think an Air type would be any benefit. Thanks guys.

Boy is it good to be back on the "dirt forum" after an extended absence (down computer)Atleast we had the car on the track this year.


As far as the post on locked rear ends,I wouldnt put a car on the track without it.Its the diffrence of spinning out our slidding through the turns.I perfer spools over welded spider gears

LOW horsepower cars that have to use stock suspension will not push as bad with a single trak,but you hope it is dry slick and not tacky or you will get passed
