Which width bracket do you prefer for which classes, and why? F1, Can-Am, and Stock Car.

Shown are a .750" and a 1.360".

I always use a .750" for an F1, since it needs all the rail space it can get. For a Can-Am and Stock Car, I tend to use the width that mates with the nosepiece I will use and whatever rail combination is popular at the time.

 

Lately it seems the trend is towards more multiple rails of smaller OD, which makes sense, keeping the chassis height lower. So there is that to consider.

 

What do you think? Thanks for your input.   :)

I prefer 1" for stock car but there are a lot of builds out their using 3/4" brackets.  I prefer the 1" as it is easier to brace.

 

For coupe and Can Am I use the 1.360" brackets to eliminate the need for axle tubes and makes for a stronger rear end.

 

For F1 I've had good luck with 1.360 as well as the 3/4" brackets.  I think the majority of the F1 builds utilize a 3/4" bracket but these are tough to brace for durability.

A motor is only as fast as the chassis it's in.

I always try to use the widest bracket the rail layout will allow, without tucking rails inside the motor box. Just my preference though.
I have done some F1 and Stock cars using 3/4 noses and 1 brackets with the rails inside and outside the nose that seemed to work well.

I just use 3/4" for everything!  Simplifies what I"m building as I tend towards multirail anyway. I have used 1" and 1.25 but think the 3/4 is the way to go for most applications!

I like to use 1" and wider brackets because I can change motors without removing the rear axle! The wider the bracket the easier it is.

Thanks, all answers have merit. But I like Dom's take on it best. I agree about 3/4 being hard to brace, the biggest wire you can use for the inner tubes is .032 due to some gears conflict with it for space. 

 

A corollary question would be, how wide do you like your inside main rails on which chassis? On an F1 with limited real estate to make min. weight and get enough strength, I think most will agree 3/4"

Now a 7/8" wide bracket, for a little bit room for bracing and gears.
