i know some people have had certain fittment probs with certain 17" aftermarket wheels so im wondering if anyone has had any issues with 18"s or should they pretty much all fit without any probs and if so wouldnt that be a safer bet when ordering new wheels

 

The only possible problems may be with too much backspace. My DC-1s have a 4.53" backspace and -12mm offset. A positive offset could cause some fitment problems, I guess, if the backspace was close to begin with.
