small tube or big tube chassis

Chassis design plays in as well .
Stiff transfers faster . Returns faster too . So not loaded as long .

It doesn't transfer as easy , when it does it happens fast , then its hard to keep it there ; ie it rolls over to the rt frt but is hard to keep that transfer .
Then it starts back to the rr and finally lft rear all suddenly .
The chassis is a spring , a stiff spring is less compliant then a soft spring .
Therefore less forgiving .
Personally i don't think they make the big tube chassis for the higher weight classes or bigger drivers .
More for the high g force tracks and high bite situations .

Flex is involved here also there is very little flex in most big tube chassis .
That goes hand in hand with the stiff spring .
Though design would come into play .

What are we calling big tube 1 1/4? thats stand diameter good for any weight, some companies offer an 1 3/8 RS rail and they are fine for any size driver, now some companies offer 1 1/8 chassis, smaller drivers and saturday night tracks, or where bite is lacking

Seems like your typical weekly racer would be better off on small tube then. I’m in NY on 33s and our tracks don’t really lock down normally.
