They won't be an easy plug and play, so be prepared for some cutting here and there.

Mine were, went straight in? did i do somthing wrong? I use mine on the road every day and am guessing i have got about 5000 kms out of them, admitedly they are very tired now and need replacing but it not a very hard or expensive job cost me $60 aus dollars and take me 2 hours and im set for another 4 or 5 thounds k's. Id run the single ring ones, there cheaper and give you so much more over rev, i gained 1500 rpm at the top on mine.
