    I just got a set of 17x9 Weld S77 (30mm) wheels delivered. They fit the back great with no issues. I am having a set of M&H Racemaster drag radials mounted on them tomorrow.
    Besides the obvious advantage of the taller sidewall and larger contact patch; the weight savings are significant.
    Stock Hellcat wheel tire with ~300 miles = 64.5LBS

    Weld s77 17x9 wheel = 21 LBS.
    Brand new M&H Racemaster 17"x275 = 30.9 LBS.
    Roughly 52 LBS for the combo for a savings of 12.5 LBS per wheel. Any time you can up traction and save 25LBS in wheels/tires is a great day! I fully expect to 60ft better than any 20" drag radial, and to do so with less shock loading to the drive train.

    And without further adieu Pictures!

    Thanks for posting this. Do you think a 17x10 rim would have fit?

    If the offset stayd the same the wheel would get very close to the swaybar. It has roughly .5" of clearance as is. I think you could squeeze it in if the extra inch was added to the outboard more. Maybe you could run a 325 then?

    275 & 28" tire on a 17" rim ? I think you would have been better off with a 305 & 29" tire on a 18" rim but looks like a nice wheels just no 29" tires in 17" sizes avail.

    It's all about saving weight, I'd go 16" if I could. Also the shorter tire lowers the final drive a touch.on

    I got the tires Mounted yesterday. They look seriously meaty in these wheels. As soon as I have a chance to put them in the challenger I'll post pictures.

    DAT Sidewall...

    Pics as promised! The combo worked fairly well. On the cars first trip to the strip we got a 1.635 60ft out of them to yield a 10.985@127. With a bit more heat in the tires and a cooler day I think there is more left in it. Very happy so far with this setup.

    Nice write up/pics. Question, did you go to the drags yesterday with the OEM driveshaft still on your car?

    The OEM shaft was on the car and stayed that way!;-). Having a setup with a smaller wheel and taller sidewall helps with the shock that breaks things. I don't anticipate braking a shaft. If I do, oh well.

    Ok thanks. I am hesitating going with the 20" DR's with the history we have been reading, until the drive shaft moves up on my priority and spending lists. My favorite strip is 120 miles away, getting stranded up there will not be good.

    Why would you not go with a wider wheel than stock? I too want more sidewall, but I also want more width. Would a 17x10.5 or 17x11 not fit?

    Given I had heard of no fitment at all for a 17" wheel I elected to play it safe. Also, even though it is 9" wide the extra contact patch I get is huge due to the taller sidewalk. When warmed up I can stomp the gas pedal at the track without wheel spin. Putting an unnecessarily wide wheel/tire on the car only adds weight. If I run into a situation where I can't put power down I'll look elsewhere for wheels.
