It really made that big a difference?? I've been meaning to do it ever since I got the car but I just keep putting it off (seems like other projects keep moving ahead of it on the priority list). I always figured it would just be a really minor, subtle difference? I wonder if that's why the 135 and I have issues with heel/toe? It's just never been as smooth and effortless as it is on the E36's I guess it's time to move this UP on the priority list again... .
