I think it could be relevant to what you want. 1400kg is around just under 3100 lbs. My car weighs 3250lbs/1474kg (no fuel no driver) with a full roll cage and full aero. HOWEVER, I have a supercharger that is almost 100 lbs, I do not have carbon doors---I have gutted OEM doors, and I have DCT (50lbs more than a 6-speed), and I have a sedan (which is around 50 lbs more than a 2-door). If you were to do a build similar to mine without a supercharger, put in carbon doors, and you have a coupe that's a 6-speed manual, I think it would get you to where you want to be. On that first post of my build thread, there is a full listing of what is on the car. And there's a bunch of pictures to show what it looks like. And my car is by NO MEANS as light as it could be. There are quite a lot of things that can be done to my car to continue making it lighter. But the truth is, the car is very fast as it is, so I haven't been in a hurry to spend the BIG $$$ to get much smaller weight gains. (I do want carbon doors though.) |

It's easier if you're willing to give up all luxuries like power windows. My E46 M3 sits at 2586lbs with no fuel and a full cage right now. I've pulled out about 1000 lbs so far with no structural CF parts.

I have the full package. Great parts; really well made with the exception of the Ti screws. Better than the other options I have seen and had (BW, Fall Line, etc). Plus they have given me fantastic tech support and custom length end links, hardware, etc to correct some clearance challenges I had with my eibach sway bars. I think it could be possible to make the Ti screws work with loctite but I have already stripped half of them. Plus I frequently find they loosen on their own. Stainless is more durable and can handle more tightening torque. This is one of the reasons that I'm not big on converting bolts to Ti in order to save weight. Weight savings is minimal and hassle is increased.
