Rookie here, pondering on building a Modified. I was looking for any advice or tips on the Modified class. What type of wheels, axles and canting to use or no canting to be used.
Car body designs - The Modified Class is better to have a more narrow car body design? Or the car body design does not really matter?
Are you allowed to put the 4th wheel in the car body? Or is that only in the pure, stock and super stock classes?
Maybe for a rookie, I should just stick to the Stock Classes?
Thanks in advance

Gravity Power OnlyOne Modified car per Builder name.
Once you enter a car in a builder name that car must remain
with the builder that it was entered with.
You may use multiple builder names but each car that is entered with a builder can only score points for that name.
You can use any car that you have built over the years as long as they meet the race requirements.
Cars are staged straight down the lane and the wheels pulled away from the center rail and body of the car.
We allow further staging instructions for entrants, they must be in the shipping box with car/cars on race day.
Entrants that are live have the "option" to stage there own cars.
2 runs in each lane with the lowest total average time the winner.
No running, touching, or stepping over the track.
No touching any ones car.
(other than to stage own car) Must conduct yourself in an orderly manner.
