4 bar lengths

[money17]

I have top bars that are 17 and lowers that are 15 1/2. If i changed top bars to 18 or changed both top to 18 and lower to 16, what would that do? Good in dry slick on a super?

Thanks

Just by making these changes you will lengthen the wheel base some, changing the top bars by 1" and bottom 1/2" you will change the indexing of the birdcages also slow down indexing reaction on the birdcages in motion, move some rear % out very minor. Unless you need to change the wheel base for track rules I would not make any bar changes. Try and stick with chassis manufacture specs on bar length if any I would want to shorten the bars.
