Yeah I like a bit of lowering
Though after a certain point lowering the car, without substantial attention to the suspension components, in addition to the springs, negates benefits and just becomes a fashion statement for show cars and uberbling merchants.
The spring companies are making money off many customers without providing a wide area of improvement often they get the rates wrong and have to "adjust" them after they've sold thousand of spring sets, and received many complaints. If those same springs were a factory option, the volume of the complaints would be heard at the North Pole (still there is it? - not melted away yet?).
Does the 300c need stiffer lower springs? In my opinion...... and remember this only what suites me ..... yes, but not much stiffer because I don't want to trade off too much ride quality for improved cornering power. I believe I would examine stiffer sway bars first, but they do nothing cosmetic to the car .... all steak no sizzle!
I like the Lotus (car) philosophy "spring softly and damp well"
.... why am I tempted to add "Grashopper" to that statement?
The roads are not as smooth as glass. The ride become too stiff and without compliance. Comfort become chiropractic territory. Bumpstops are not springs.
Show cars luvverly luvverly.......... road cars not........ or I'll rephrase that "not too much" without re-engineering most things in the suspension department.
Just my opinion.
