I had an Austin Mini with the 1.0 and the shortest speedshift of the road version (pont 3.65 :1) and on 12" wheels (full stock), it was an great car... !
I have enjoy to find this mod, the (great) sound and the karting spirit of the Mini !
Now, it would be perfect if you can proposed other versions of Mini :-D :-P (or just differents setup of pont ?)
For example the same version of my Mini, it was very nervous (the 4th gear up to 150 kph at 6000 rpm:-D) and little more performing than this 1.3 on 13" :-P
I like to find a fun car with poor performances in a game, it's difficult.. (i'd tried to work a Mini 1.0 45 bhp on GT Legends but the game didn't accept this low power ^^)
I have make the Smart Roadster mod for GTR Evolution too.
Great job and sorry if my english isn't perfect ^^
