I used the UK spec for about a year and a half and won't go back to it. After switching back to near stock specs, I am running a tad more neg camber than stock. I realized how much the car understeers with the UK spec. Safer yes but I don't care for how it handles. I am also running a 27.2mm bar out back and I don't find the car dangerous at all.

I really like the uk specs. I went with slightly more neg camber in the front and love it. Makes the car feel wider imo. I won't go back to us specs.

 

my car already understeers alot, i dont think the uk specs are for me if it make make even more understeer.

 

Use the UK specs sans the increased rear toe-in and there won't be drastic wear problems. There might be more understeer because of that increased toe in the rear.
