IMCO standard length lowers. I'm guessing it's the additional bow lift/leverage that helps. No extension boxes. I have both labbed p5-x's and labbed bravo's to try with this combo. Appears I have the factory X of 18.5-18.75". Full cabin. I will try to post some results of the spacers, it makes sense because shorties definitely do not work on our boats.

Eliminated572 What drive ratio do you have?

Sorry for late response. 1.35 gear.

I am removing my XR Max Machine uppers (only one hour on them now), and going with SCX's. I removed the 1" spacer because it didn't do much of anything. I did repower this year with new engines and larger whipples. In the 850hp range so drives will be a constant stressor from here forward. So I have an awesome set of uppers for sale, and I would like to trade someone their SC shorty lowers for my -0 SC lowers. The SCX is about 1" deeper than an XR.
