Smh...listen to me. Try to buy them. After you checkout they will either not charge you for them or you get an email saying they aren't ready yet. For the last time...There are NO lowering springs out for our car available to the public. I won't comment anymore on this until they are released.
I prefer the H&R spring over the Eibach. I have them on my Mustang and I love the feel. Whenever these leave the R&D stag and become availible I will get a set. Just need to find good shocks to pair them with.
