I have not yet measured the roll bars on my AX sport but think they are 19mm front and rear. Although I have not driven the car that much, it still feels like it rolls in corners a tiny bit more than my old 106 rallye (Serie 1) did. That had 22mm roll bars front and rear.
Would it be a good idea to change to 20 or 21mm roll bars front and rear? Has anyone done this?
Thanks for any help,
(sorry for the English! I could translate to French but fear it may not work very well..feel free to answer in French- I can translate
