Am sure this has been asked so many times before but I can't seam to find it want to stay with 16''s and want them as light as poss looked at the compomotive mo5s but read that they are more of a rally spec wheel so not as light looked at pro race 3s but they only come in 15 or 17 also what is the widest tyre I can get away with and what off sets best should I run a different of set at the back instead of using spacers any pics would be great
