I was going to run the "Cobra Classic" in my car. You need seat headrest support for a engineer modified transplant in NSW. I'm pretty sure these seats are legally ok for NSW registration.
So, check if the seat is complied for street use. I almost got screwed with my Sparcos, and had to get a Boat racing parts company to fax me a copy of the engineering certificate for the "Sparco Sprint" aftermarket seats in my Datto.
There are a few chinese aftermarket seats getting around that aren't compliant, and will get you a defect, and the poorly built seats will potentially kill you in an accident.
Maybe I'm over-dramatising, but it will get you a defect if nothing else.
