I have a Riviera that I want lowered about 2 Inches in the rear. You don’t make lowered springs for this car, something about not enough demand. So what I want to do is cut the coils. Is this alright?

A -Frank, in a lot of cases it is fine to cut the coils. However this is one case where it can not be done.
Your springs have what is called "pigtail" ends. The ends have a smaller diameter then the body of the springs.
The only type of coil springs that can be safely cut are those with "tangential" ends.
Tangential ends look as though they just twist off into space. The spring would fall over if you tried to stand the spring up.
Now that I have disappointed Frank, let me tell those with tangential end springs how to cut the RIGHT way.
DO NOT USE HEAT. Did you hear me……NO HEAT
Cut the coil with a hacksaw or a rubber cutoff wheel. NOT A TORCH!!!! And be sure to use safety glasses.
Don’t cut off the whole amount you need to lower your ride. Cut off about 3/4 of the amount you wish to drop your ride. Then re-install the springs and drive the car like you stole it, do not baby it.
Then recheck the ride height. If you are lucky you’ll be at the right height. If not, take the springs out and cut off a bit more.
If they are front springs you better be using a spring compressor.
Remember, there ain’t no way of making them longer, so be careful.
