corner weights

[Hoghead]

71 Std Betle with a 2.0T Suby engine, Porsche 915 gearbox, 944 trailing arms and brakes, uni-ball rear, 996 front brakes, 996 17" wheels, 53 liter fuel tank, IFS
Radiator placement is still undecided, but thinking of an aluminium radiator in the front to get a bit of weight up there

I weigh 170 lbs

I am trying to calculate spring rates for the coil overs and need to know the corner weights

Stock Beetle is about 1900 lbs curb weight
WAG with my setup and my slowly increasing girth is 990 lbs front, and 1300 lbs rear
Sound reasonable?
