Your brake proportioning valve 'thinks' your car has a lot of weight in the rear due as it is low. It is allowing more pressure to the rear brakes to compensate. You need to reset it so that it is in it's 'normal' position at the height you have the car at now.

I also wouldn't call it a small issue, if you had to brake sharply on the motorway you would have no control and spin.

I would rather lose by a mile because i built my own car, than win by an inch because someone else built it for me.
