It is because you have gone 8j on the front et33 . Ive had 8 sets of wheels on my car and the only set that didnt catch were the gold comps 7 1/2 j all round et35. Now on my car i have

Et30 all round ,the rears are 8j and the fronts are 7j .To fill the rear arches more i could of gone et25 as some people have.

That would make the car drive like crap , yes it would look good but stick a set of ecos rims on a 3 door and you will find out

Chop there is 2 things you can do. Roll the arches or take the wheels off and have them machined to et35 . That would be more than enough. Ring adrian at compomotive
