spring suggestions?

[snowmobilejon5000]

Is there a stiffer OE ride height spring out there or does anyone know a way to conjure up a way to block the stock springs to make them stiffer in the rear. I want the ride height to stay the same but I want the back to be like a brick and I can only find stiffer springs that will lower the car. I have a gutted 2008 aveo5.

For what it is worth, I have the eibach sportline springs, mated up KYB GR2 rear shocks and KYB excell2 front struts, sitting on 17" enkei RS6 rims wrapped with 205/40 R17 nitto neogens not too mention a hatch full of audio equipment. The ride is pretty good, handling is amazing. A few days ago I took the car on a 5 hour (one way) trip. I was very impressed at how well the aveo drove for that time frame
