Hey there,
Depends on your engine model. From my understanding the "bigger" 1.2L 16v engines automatically have the larger 238mm brake discs in the front.
Anything past 2001 has larger break calipers in the front compared to the first Gen. Twingos, which can cause issues with the 13" original alloy rims that only fit the early models for that reason
(ask me how I got to find this out)
Hope this helps!
