Day to day it handles just as well if not better than previously. Prior to this i was having to run a lot of positive camber due to the coilovers catching the inside of the tyre, now the spacers are on i can go back to negative camber so it doesnt tramline anywhere near as much.
the wheels are the same dimensions as the standard f1's just a little wider at 7J, plus with the 15mm spacers it feels that bit more sure footed.
They do catch on the arch when turning hard and you go over a bump however so im a bit more cautious with them on.
And yes, they are staying on the car for a while until i get sick of them.
