Tire width Relation

[C4Bird]

I am planning on running a 315/35/17 on the back of my bird, but have yet to decide on a width and series for the front (17's front). How do I figure out what width to run for good track performance and great everyday driving? I don't need to run #1 at the track, but I would like to be able to keep up and still drive it to work the next week. The car will have a subframe with C4 pieces, coilovers front and rear, and the rear will run a 4 link with panard. With a little work I should be able to fit up to 285's up front and still be able to make it turn, but is this a complementing size to the rear? What combo's do you all run, how do you like it? I have the greatest respect for the people on this forum, so any help is greatly appreciated!
