Sold the Z, had this bar and harness in the car for only 1 track day/autoX season last year.
Only a few of these bars have been made, for more info check this thread:
370Z Harness Bar
The Harness is a Schroth, 4 point Profi II with ASM (Anti-SubMarining) technology.
Installation of the bar requires drilling holes in the top strut bar covers, but this is done already. I will provide pre-drilled strut bar covers with the bar, so you can keep the ones in your car pristine and put them back if you ever decide to put your car back to stock.
Selling as a set, price: SOLD
