Has anyone used these shocks and struts?

Thanks.

 

I am also interested in these. They are a fairly decent price

 

Given that they're within a measly $150 of a set of D-Specs, I would just pony up for the real deal, if you're going to race the car AT ALL. If you're just doing drive-in cruises, cool, but for dialing in at the strip or track, the D-Spec wins hands down.
