Thank you
Maybe try Chris @ Tarmac Sports - he did a set for the BRZ which also has frameless doors, perhaps the manufacturer of those might do sets for the 350z & 370z?
I was the guinea pig for his first set on the BRZ, they worked well but aesthetically they were a bit "marmite"
Thanks for that info. I had a quick google and i can see how they are marmite. I plan to go down the aesthetic route rather than performance, so i think i might have to keep the windows closed.
