106 GTi ones tested at 120lb/in apparently.
Eibach pros tested at 115lb/in linear.
From measuring there were a few different springs used on saxos, it appears it correlates with 15" wheels on vts. Somewhere in the region of 110-130lb/in. I have some if you wanna test one
Wheel rate of that would be around 90-100lb/in iirc.
Wheel rate of 19mm torsion bars, according to sandy is 110lb/inch.
I haven't looked into any of my graphs and calculations etc for this as i'm on a temp pc, so it's all from memory, so may be incorrect.
Weight dist is about 65/35 standard.
