This is my spare tire setup I had for my 392 SRT Challenger. It cleared my front calibers but I never needed to use it. I believe this could be used on the Hellcat on the rear. (If you had a flat on a Hellcat front tire, you could replace a good rear tire with the spare and use the rear tire for the front). I am asking $130 for the spare tire and spacer. I prefer local pickup but shipping is possible. Amazon has just the spare for $300..
