Think wer'e about at the limit for a 700cc engine without costing lots.
The stock Smart is OK but slow and not good at cornering.
We have got ours lowered and wider wheels all around, it goes round corners great now.
The first re-map put it from 64 BHp to 84 and the second to 100.
A after market TIK pipe and thats about it.
A bigger exhaust may get a few more out but not much.
The main fun (as I have said before) is watching people do a "double take" when you overtake them in a Smart, cracks me up..
Got a couple of round abouts on the way home on a Dual carriage way and it's great when a big car sticks in the outside lane as it asumes it will ovr take you on the exit - only to be left looking stupid when we squirt around and leave them overtaking nothing
It' fun driving at it's limit, something you (me) can't do in a Supe.
