Hey guys, I have an extra 5 mm spacer that I'm not using now but I'd like to put it on to help bring my wheels out a little bit. I have the Track 18" Rays wheels. Would you recommend putting it in the back or in the front? Which would be better so I don't sacrifice stability and traction control? The wheels are 8" front with 30 offset and 8.5" rear with 33 offset.
