Ok I was wondering has any one took out their spare tire for maybe weight issuesand left it out? Also does any one use a full size matchin spare?

I have been driving without a spare to gain a few ponies.
The spare and jack weigh 40lbs.
I estimate this gains a little more than 3HP.

((Horse power / car weight) x pound reduction) = horse power gain
(340hp / 4066lbs = .084%) x 40lbs = 3.3 horse power gained.

The SRT8s don't come with a spare... just a compressor and a can of goop.

i took out the spare tire since i have 22s now, so its pointless. I have free towing and stuff anyway, so it doesnt matter

i left the jack inside just incase i need to jack up my car to get underneath.. but i guess i can remove that too
