Are cup and non cup springs the same?

[hipwell]

Just found one of my front springs has broke and needs replacing.

I was considering getting 4 sportlines fitted but they are 130 quid for 4.

I seen nwp are doing genuine springs for 40 quid so I'll just get the front 2.

Are all springs the same for cup or non cup? If so how come a cup is lower?

no, they are model specific, cup springs have a red and white marking on them
