bjcrown Donating Members 182 Member For: 19y 3d Posted 21/12/09 07:31 AM Share Posted 21/12/09 07:31 AM Team,I own a BA MKII Turbo. My car has been edited some years ago (I have a CAPA Flash box).From factory I have 17" rims with 235/45 tyres.I am thinking of putting on 18" rims with 245/40 tyres.I believe FORD via the WDS/IDS can set the tyre size.My question is, will the new settings stay within the car if I change/load any of the tunes (including the factory one) from my CAPA box???

I've changed from stock 235/45/17 to 225/35/20 (yes bulk wheelspin). Cheers guys Link to comment Share on other sites More sharing options...
