My Qubo has always sat high in the back, with a very large wheel gap, it's not the trekking model. I think it's because I have removed the back seats for my work tools.
No aftermarket lowering springs available for the qubo, and I mainly wanted to lower the back to level the car out with the front.
Finally found the Grande Punto has similar(ish) spec rear springs, but about 34mm shorter. Overall I think it has dropped the back about 50-60mm and now sits much more level.
Also very happy with how the headlights turned out after a recent weekend cooking and painting them
