I want to lower my 08 coupe and the Megan Racing springs really interest me. It says they are of 09-13 and i was wondering if i could put it on mine or if i would need anything else to install and about how much it would cost.

 

There's been a few examples of them, should be a medium drop, I'd recommend the F&R camber arms and rear toe bolt kit, or the rear set for sure.
Oh, and welcome to the site!

 

this helps me a good bit and gives me a lot to think about as well. and thank you for the welcome
