How much weight is there actually in the rear of a corsa? Not much :S

Spare wheel and tools are quite heavy - maybe 25kg to 30kg

The trim doesnt add up to much when just the rear is tallied up. The seats from memory arent that heavey - just foam with a wire frame.

I think most of the weight to come out is from the front half of the car/cabin.

I guess what I'm faffing on about is... 'How much difference does stripping really make to the height'

And also... The height will depend greatly on the spring poundage.

I understand kgmm more these days so I'll use that.

Say you had 200kg at each corner of the rear

(To convert kg/mm to lbs/in, divide by .0179. To convert lbs/in to kg/mm, multiply by .0179)

200lb springs are 3.6kg/mm. So for the 200kg, they springs would compress 55mm (5.5cm)

For 300lb springs, 5.4kg/mm they would compress 37mm (3.7) for 200kg of weight.

for 175kg (No idea on realistic rear corner weights for a corsa but for example a 50kg saving at the rear alone)

200lb springs would drop 49mm (4.9cm)
300lb springs would drop 32mm (3.2cm)

So..... do you see what I'm saying. The spring rates are prob more of an issue than height.... unless the springs are progressive.
