Hi all. I've got a chance to get my hands on a really good deal on a fmic, but was wondering what kind of size is ideal for fitting on the coupe? The one in particular is 600x450x75mm although i get the feeling this is a little tall, so i might have to get a custom jobbie made. If you can help me out i could get a group buy together for a filthy cheap deal. The one i mentioned above has been tried and tested on other cars and is a whopping.....£109.99!

Thanks
Toby
