hey AcsRcool, you will definitely need to lower. i had the CDR9's, they are a tight wheel, but i sold them b/c everyone around me started to get them after i had them....so now i need some new wheels.......but anyway, the wheel gap is bad. i have the Apex-i WS coilovers sitting in my trunk that have been there for two weeks waiting to be put on. the wheels will look tight and make your car look better, obviously, but the wheel gap is just as bad as stock. so a bit of advice is to start saving for your suspension very soon. just my opinion though.
