Don't buy a kit go buy a real aluminum shelby like I did, Those are available from shelby american, there street legal and they are convertibles and unlike the gtsr you don't have to have a race team. I am a nasa member and longtime drag racer and when I sent my 20k and filled out the credential paper they sent me they said sorry I had to be a race team.My cobra is set up for the street and with the ta radials it runs 10.7 at almost 130 and if I were to put on race coilovers and wheels and tires and maybe a brake upgrade I think it would more than hold its own with the other car if not beat it.One thing is for sure shelby hold the money kit cars don't and they only made about 46 total aluminum ones since shelby started making them again a few years ago and about 15 of those are still available but when they are gone so are aluminum cars.Shelby is an old and mythilogical man and when he passes you will be glad you bought a real shelby and not someone elses kit.Don't get me wrong I have seen kits that are works of art just totally awesome , I had one but the first two questions everyone asks is, is it real and is it aluminum, and no one wants to say no.
