Clazzio Leather Seat Covers - The Most Customizable Clazzio Site - FREE SHIPPING on orders over $350 Retail 299.99 with any color stitching you want or cheaper with pvc. I didn't go with the PVC but I also didnt order them direct. Bought them on ebay for 100.00 or so cheaper. They do the job.
Can also tell my car is a 7at so I have the GTR shift knob with 370z oem manual shift boot. Worked out nicely to tie the interior together. Much better look than stock. I'm just waiting for my illuminated kick plates and touring pedals to finish a semi conversion. Already running rear cargo cover and rear speakers, basically everything my base didnt come with.
