I know this has been asked one million times, but I need help. I have a 2014 SRT challenger 6.4 6sp, and I dynoed at 784 RWH. I have Nitto Nt05/315 40 20 and can not get traction to save my life, I need help this must stay a street car but I can run R series tires. I am contemplating MT/R with 17 inch rim, but I need a good rim at a reasonable price. I will take used rims but if it works out, but I would like the option to match the front. Six months ago I bought demon replica rims all the way around and I thought the Nitto's would work, nope. please let me know what to do I live in Florida and don't know where to turn, I m even contemplating going to an automatic just for the traction.
