So, with the help of some internet friends, I can say it's a Cat 2000 SE from 1997 !!!
--> Not so bad for 17 years old...
So now, how can I modernise it without changing his ADN...
For me, this generation of Cat 2000 (EC/SE/98) had 3 caractéristics which should be saved :
A/ Laydown suspensions which gives to the car a fantastic look and his efficiency
D/ Not straight transmission which is a real curiosity...
N/ Body and undertray and wing which gives to the car his smooth and low look.
For the rest, I'm free to change... And that's what I'm thinking...
I could let the weight repartition and buy some saddle battery but it's not "light is right" and I have no money to buy them so...
I keep my shorty batteries used on my Ynot FF buggy and I see how it can help for a good weight repartition... Here what it can be :
I hope it will be good...
