just curious, can the stock 20" SL rear wheels be used on the front? was thinking it might be a convenient if I could run the same wheel/tire setup all the way around especially if I wanted to have a backup wheel and tire.
I know this must have been answered in some other thread, but couldn't find it in a quick search
thanks 
I run 18" base rear wheels all the way around.
I would think you could do the same with 20' - rear offset is +45 and fronts are+42 (I think)

okay - I am not well versed in offsets. would a +45 put the wheel further out from the center than +42 or further in?
never mind just looked it up and a positive offset puts the mount closer to the front of the wheel and would put the tires closer to the center of the car - not sure I like that, but it is only a 3mm difference?
From day one several of the guys have been running the same size tires all the way around.
Check with Mitch @ https://store.revdynamics.net/ He dose have some used wheels that might match your Slingshot... If you ran non directional tires you could rotate them also.

I have had zero issues with mine, love the way it handles.
There are a few of us doing the same thing. I like having every thing the same size - easy to have a spare ready at all times
just curious as to why slingshot has a bigger back wheel....is it for stance or some other reason.....like you’re always going down hill so you can get better gas mileage?
Oh, I don't know....
Adjustable shocks.
Polaris decisions.
Pick two...

You could run the stock rear 20 all the way around. You'd never notice the 3mm difference and while I have not done it, I can't think of anything that would rub. I run all kinds of different wheel sizes depending on what I'm doing but typically I run the stock SL 18s up front but my rear is typically a 15" or 17" drag wheel. Mainly because drag radial and full slick tire sizes and selections can be a little limited in an 18 or larger. But there's tons of options in 15, 16, or 17.
Drag Radial 17"
Full Slick 15"

My best guess would be traction.
Old thread but just wanted to add some info. I’m running 20x9 +32 up front, 20x10.5 +40 in the rear with no problems. Tires are 255/35 and 305/30.

Looks may have played a role, but tire size is the easiest way to change the final drive ratio.
