Qustions On Springs & Catalytic Converters
Any good write ups on how to remove and install front and back springs?
And my Catalytic Converters are 10-11 years old. I dont have the second but I do have the ones up by the engine that need replacing. Anyone have a good website to buy high flow aftermarket ones?
Thanks in advance.

I stongly recommend the KLANN type compressor. It is the ONLY one which will work without you getting in a sweat when you see the springs bulging out and ready to fly across your workshop 
There are some cheaper versions available but I can't guarantee they will hold the pressure of the compressed springs. Just shop carefully

We replaced the front springs with the ones I bought from a forum member.
He said they were oem which they were comparing to the ones we pulled out.
BUT, get this, the driver side spring was cut about one turn of the spring. The passenger side was NOT! Why would anyone do that?
My front was close to touching the tire to the fender. After swapping the new springs the car went up about half inch to close to one inch. I THOUGHT THE OEM SPRINGS WOULD LEAVE A TWO INCH GAP????
So weird, the shocks where not oem. Could this be why it only lifted so little? The shocks are Monroe and they are about 7-9 years old but I'm not sure. When my car hits a bump it is pretty hard. Also if I'm parking and if I hit the side walk edge going forward the hit on the tires are very hard as if I had no springs, weird the way it feels.
Most want to lower their car but I want to raise to stock. What's going on with car? Should I buy the oem shocks? Will that lift the car at least an inch?

Shocks do not raise the car no matter how much gas pressure they have. Shocks control bounce (compression and rebound). The springs alone control the ride height of the car.
It sounds like you got a set of OEM springs for the Euro spec - and if one of them was cut, you got screwed on the deal.
There should be some members on this forum that have their US spec OEM springs laying around. Anybody?

Btw, the spring that was cut was the old one in the car not the ones I bought from silence.
Could it be that the car silence has and mine came originally with euro springs? Or last owner switched from USA to Euro springs?
Where can I buy the front USA oem springs??? Anyone here have some and how much? Can someone PLEASE post a picture of the USA springs. The ones I have got 9 coils that circle around front top to bottom.
Oh, and silence also sent me two other spring which are taller than the two we installed. And the spring is a bit thicker. Could these be for the front?? That would be crazy if we installed the back springs in the front n vice versa!

Sounds like you just figured out the problem. The rear springs are slightly smallar in diameter than the front. I have a set of springs I just removed from my car and will see if the rear set is taller in an uncompressed state.

I bought them from the member SILENCE and he lives in Rochester mn so I doubt he used euro but I pmd him to see if he has any ideas.

I measured my uninstalled C36 springs and the taller springs are for the front and they are thicker and have a slightly larger diameter so it does look like you have installed the rear springs in the front.

Can one more person confirm that the taller thicker springs go in front?

Of course they do, think about where all the weight is... The springs in the front are thicker and taller to account for the weight of the engine.
