Whitelazer. You are not alone. First off lose the p-dub bumper. It is too hard and puts too much pressure on the nose of the chassis. I have split 3 myself and about every other gut at my track has the same problem including even a gut with a brand new BMI chassis!!!
This is a major problem!!! Its the screws that are coming thru the chassis causing it to split. Best advice, ca the countersunk holes and use screws with bigger heads.
I am thinkinh about switching to a corally at least their chassis dont split.
And before anyone bashes me about" stop hiting stuff" just remember people do make mistakes and hit a board going thru a tight chicane sometimes. We are not pro level drivers.
