How to tell if cup springs are geniune??

[sazzle]

Wondering if anyone can help, I've just bought what I think are a set of cup springs off ebay for my mk 2 172.
How can I tell if they are geniune renault cup springs and what are the difference between standard sport versions, are they shorter or have a noticeable drop ect....?
Any help would be much appreciated.

172 Cup springs have a yellow and white stripe on them somewhere I believe, with non-cup having two white stripes.

I think...

Either that or it's the other way round lol

Cup springs are slightly lower (~5mm) and slightly stiffer, and have a lot less 'coils' on the actual spring than the 'normal' ones.

The cup springs off my 182 have red and white painted marks on the top of them

The springs do have the yellow and white stripes painted on them

I am changing the springs over tomorrow so hopefully the sport ones have the two white stripes like you suggest.

I will post some pictures up tomorrow for comparison.

Thanks for pointers =)

Yup. I'm on my 3rd set now, and they all had a yellow and white dab of paint on them somewhere.

Lots of miles, lots of track use.

Never noticed a real degradation in performance, but with the pounding the standard springs and dampers take, I always thought it best to give it a fresh set every now and then.
