So here we go. I believe the question was what is the best GT40 kit? You MUST decide what you will do with the car. How are the roads in your area that you will drive on. Do you intend to drive lone distances on freeways like we do out weat in Calif. USA. Some track days, lots of track days, real racin? All of these thing must be finalized in your own mine first.
Then think long and hard about power levels and be honest about it to youself. 300-350hp will be fine with all of the current tranaxles. If you are a 500hp person then you are in a whole new ballgame. Your normal crusing speeds will be VERY important when you start thinking about gearbox's. A good final drive ratio would be on the order of .8 5th gear with a diff ratio of about 3.5ish for freeway use cruzing at 75mph or so. Remember one thing the gearbox is the heart of the car. Make sure you are fully informed on this. Should you be using you car for in town driving or a lot of track time a lower ratio final will be OK. Lower would be 3.90ish on the diff with a .8 5th gear.
If you think I'm all hung up on transaxles then you are correct. Do a search on transaxles, renault, audi, quafe. LSD, etc. and you will see why. This may be the most discused topic on this forum. If you get the gearbox right the first time I think you will be happy with whatever car you buy. IMHO, there I used it, The added cost for a LSD is well worth it unless you intend the car to be used for shows or very low performance type driving.
Lastly the bad news. Make sure you know all there is to know about body fit and gap line adjustment. I think some of these cars are very nearly spot on as you recieve them and will require little "body work". My GTD on the other hand was a nightmare. Just make sure you know what you are getting into with whatever builder you pick in the end. Look at the way cars are delivered as far as body fit is concerned.
That's my 2c's worth.
If you take your time and do your homework and do good work I am sure you will be happy.
