If your just looking to get the car lower and play with the height tein basics will do the job(Dont expect the car to handle really well), A lot of people bag on Megan coilovers but the only cons to getting megans is having a stiff ride, witch i dont see as a bad thing as long as you set them up right with the right wheel and tire combo. Unless your car is going to be on the track 24/7 then go with some really high end coilovers(2,000-3,000+) or even go custom and get custom spring rates etc...I have had and driven many diffrence set ups and overall best bang for the buck($900 or lower) if your talking about being height adjustible and hard but not super harsh ride i would say megans.Good for track and street.
But honestly when i was looking into coilovers everyone told me everything was too stiff and to harsh for the streets so i just tested cars at events and finally seen what was the best route for me(drviing style). So i went Tein Flex cause you can get really low and still have really good shock travel.
