Im just keen to lower the back of my Bravo because stock its way too high, front is fine for me, will i loose any aerodynamic performance this way or have any type of negative effect if I had to say lower 40-50mm?
Lowering only the back will have detremental effects due to differnent spring rates. You'll get a lot of bounce from the back and the car feeling as if it is lifting off the springs.
I have a set of coilovers for sale. If you're interested, PM me
All the kits I see only lower the back by 30 and front by 40-50 and I don't want that, also 30 is such a min amount.. so I guess I need a new bottom spoiler/defuser which is just closer to the ground?
