wider rear wheel base ?

[mando]

I'm running in an outlaw class race. I'm running RS s with a 3 wheel design, we had an exibition "shake-down" run last night, my car seem to be running well with no wobling or fish tailing. the only other car that was any competition had a set of custom rear wheel that had a wide hub, so the rear wheel base was about 3/8 -1/2 in wider than mine. i know this would not be allowed most races, but it is O.K. in this one. Dose any one see any advantage to widening the wheel bace like this ? Would it keep the rear wheels completely off the guild rail, or at least give you a better margin of error for over steerage ? Any thought would be great, this "outlaw" race it throwing a lot of curve balls at me

The distance between the front and back wheels is called wheelbase (length) and I beleive the distance between the front or back wheels in relation to themselves is track (width).
Having a wider track isn't necessarily an advantage in stability, however it can allow you to place your ballast in tighter around the rear axle if the body is wider. Normally the body is 1 3/4" wide and everything is placed inside that. If your body is widened you would have more width to place your ballast. This doesn't sound like the case with the other car, due to the wider hubs as to why he is wider.
Something to keep in mind with a wider car is when all the cars get squirly they would be more likely to bump into each other. I think that might be be bad
The bigger key to stability is placing your ballast low.

I don't necessarily make the back wheels on my cars any wider, but I do intentionally narrow the front wheels.

The reason for narrowing the front is, when the front dominant wheel rides the rail, the rear wheels should not rub the rail. With most of the weight on the rear of the car, you really scrub a lot of speed when a rear wheel rubs.

That seems like the biggest reason to make the front end narrower than the back end.

Just my $.02 worth.
