hey all,
i just purchased some rims and i'm waiting for them to come in. i want to lower my car a bit and i've been noticing that everyones choice has been H&R Springs. i was wondering if i need to get any other components for my car besides the springs? All help will be greatly appreciated. thank you! i found some h&r springs on a website and i was wondering if they were "legit" or if you guys know where i can get a set. thank you!

here is that website;
