I have been wanting to add to my standard Z the ZR-1 style carbon front splitter. However because my car diddn't come with the required reinforcement bar, I have to either add the factory bar, or go after market. If I go the factory route I need to remove the front bumper cover which I really don't want to do. I just see to many things going wrong in that process. Scratches, not fitting right etc. The after market is an option but I have not been able to find one the looks like the factory unit or can withstand speeds in excess of 140 mph. The factory assembled parts are retail ~$2,400.00 not including labor which I don't think I have the skill to do this myself. If any of you out there have found a good solution to this want of mine please let me know.
