smackdown chassis

[W2racing]

We're looking to buy a newer MB smackdown chassis. What do you guys think, square tube or round? Or doesn't it really make that much difference?

I would say square tube. They are stiffer so more responsive to adjustments and don't wear out as fast.

I asked this same question of EPJ a few years ago. His answer was, and I quote, "I cant tell the difference between the two."

I second what Huck said.

I agree with hucktyson and MasterSbilt_Racer, heavy rail square tube car worked a lot better for us than our round tube smack. Round tube car wasn't nearly as responsive to adjustments.

Yup sq. here too

Thanks for all the responses. It sounds like we'll be going to a round tube smackdown, based on our shock builders advice. He also said the chassis is worn out after 75 nights. Comments?

I had a square tube and then bought a round tube for this past season. I preferred the round tube over the square.

Maybe the round is. I have seen squares with well over 125 shows win races.

Is there any correlation between round tube and square tube based on engine horsepower?

i had a round tube with 35 or so races on it and started to crack up to where i had to weld on it every week and i had a square tube car that had about 40 races on it and never welded on it, just my thought but never felt any difference until it started cracking up
