Experience with C4 suspension kit for '47-'53 from Flat Out Eng.?

[1MADTEXAN]

Anyone here have experience with the C4 suspension kit for a '47-'53 from Flat Out Engineering?

I'm asking because I'm hoping someone who's installed this kit can comment on what wheel diameters, widths and backspacing I can expect to fit inside stock fenders/fenderwheels.

Ideally I'd like to run an 18"x7" or 8" front and an 18"x10" rear, widening the rear fenders 2" or slightly more if necessary for the latter.
