Honest opinions please.....

 

My brother has them on his 99 Firebird LS-1 car. He loves them. After riding with him and having him scare the poop out of me, I would have to say I am a believer. I used to autocross, and if I still did, I would defenitely buy these. I don't know if you need them for street use. If your car leans, these will take care of it, though.
The springs are linear rate, not progressive, so be prepared for a rough ride compared to the progressive DMS and Eibach springs.

 

They look pretty cool, and the picture looks like eibach springs are used. There is also a diffrent model ( same price ) to use koni shocks with.

 

Are those really considered coilovers? It doesn't say they are, and I thought coilovers were a shock & spring combination.
