cupkit

Hi guys anyone used these bad boys before. Look at this on eBay H&R Cupkit Suspension for Mercedes Benz W208 (CLK) Cabrio/ Convertible 40749-4 | eBay If so I'd like to hear thoughts. Thanks W208AMG

What are the opinions on the H&R cup kit? In particular the actual shocks themselves that make up this kit. I know the springs will be ok but does anybody know if the shocks are any good? cheers.
