Your cross weights should be within 5% of each other. So, if you add the left front and the right rear together, they should be close to the total of the right front and left rear.
I remember the fronts of the GTI being around 600 lbs and the rears to be around 300 lbs. That total gives you 1,800 lbs, so I'm off a bit, but ............
Just make sure you SIT in the car when they are doing the corner weighting. Also, make sure that the cell / fuel tank is where you want it to be at the end of the race, hopefully, a little over minimum weight, so you don't get caught being under-weight.
