Might be going to the track soon

I might be going to the track in a week or two. The stock rear springs in my car are sagging. The front end is sitting about 1/2 inch higher then the rear. How badly could this affect performance? I was thing about ordering the Eibach Drag-Launch Springs and just swaping the rear spring(won't have time to change the fronts for a while). How would this set-up work? I Need advice. Thanks!

it will be fine. dont worry about it. it may actually help weight transfer.
