Limits for increasing car's ground clearance
My aim is to increase the weight I can carry with my car. I was told that I
should replace my rear coil springs by installing "harder" ones.
The case is that will lead to an increase of the car's height by 2 cm.
I'm wondering if that is acceptable in terms of vehicle stability & driving
So are there "official limits"?
For example, for changing tires there are limits of -2.5% and +1.5%.
Thank you in advance.
