last night me and my old man put my teins into the vr4. and i would have to say that it was the simplest mod ever. i was expecting it to take a little while but we did it in less than half an hour. now all i have to do is just play with the dampening force till i get it how i like it. anyway if you considering getting teins and are thinking about getting someone else to do it, just save that extra cash for another mod.
