LRB Speed in Clearwater, FL has just finished up designing a set of aluminum door cards for the 370Z. These will shed approximately 8lbs from the car. Stock speaker placement is retained(or not, optional), as well as the mirror adjustment knob and window switches. Pull straps included. Landon is getting pricing on powdercoating today, but since this job has to be outsourced, he will need a minimum of 10 orders for this to become an option.
Note: I am in no way affiliated with this company and stand to make no commission or other financial gain other than the savings of the group buy price.
It may be another day or so before we have a set group buy price as he's waiting on the powdercoat quote, but you guys will know as soon as I do.
Update: pictures added
