I had fitted cobra springs (super low front and ultra low rear) and monroe gt shocks to my sedan. I got the drop i was after
but found the ride to be total ****. I could compress the springs by hand!. The car wallowed and bottomed out to the point i couldnt really go beyond 80km/h without the "handbrake" bitching. Have since removed the cobras and put stock springs back in.
Next plan was coil overs , but need feedback from those who have fitted coilovers, on how they ride
