Cool. You guys can run the tires off of a BMW i3.

Maybe, I guess. Dunno if the load rating is gonna fly.

Found this pic on the ol' webz. Can't make out the details on the sidewall other than it's a Bridgestone Potenza.

Got an answer back from Weld. 20x7, 4.2" backspace and High Pad and requires an 1/8" spacer.

Now to figure out that tire....


CORRECTION:
- The fitment above is for a narrow-body Hellcat.
- Widebody Hellcat 20x7 fronts come in two options... High Pad, 2.25" backspace and -45 offset OR a High Pad, 3.8" backspace and -6 offset. The 2.25" BS wheels fit flush with the fender, but have the wrong offset/scrub radius. The 3.8" BS wheels have the correct offset but sit inboard 2" from the fender.
- Both wheels require a 1/8" spacer.

I'm picking the 3.8" BS version. Would rather have the car drive better and don't mind the wheel being recessed into the fender.

Did Weld have a suggestion on the tire?

I made a correction in my post above on fitment. Weld specs out different offsets/backspacing on Narrow and Wide body cars.

Same choice I would have made. you planning on that being track only, or are you going to drive around innocently with skinnies on the front on the street?

It'll see some street. Not all the time, but there are times that I'll be on them out in the world. That's why I wanna do the 20x7 S71s. Should be more durable than a track-only 18x5 and handle better. Won't be as light, but will be lighter than the factory 20x11s.

Not 100% sure till I go to bolt them up. Weld's fitment guide said it was required...guess we'll see.

Now I just need to measure ID to order my hub-centric rings. I'll unbox them and post pics when they hit.
