Default New struts/shocks vs New springs

I am wondering what would be better at getting rid of the insane amount of brake dive my 2012 has new struts/shocks or new springs? I already have a strano performance sway bar kit and I don't really want to lower the car a lot because of how bad the roads are around here. I'm leaning toward struts because most of the springs could be too stiff and they lower the car too much.

If I had a chance to do it over I'd get struts/shocks over springs.

Boss 302 springs would reduce brake dive and don't drop the ride height but their F/R rates are not ideal.

Steeda competition springs would be better and only drop the front about 1/2 in.

However these both would wear out your shocks in short order.

I recomend koni yellow shocks.

This is kind of a loaded question.

Personally, I'd vote for lowering springs to reduce brake dive. This is an over-simplification, but the shocks and struts control how fast it dips and the springs control how far it goes. (again, simplification)

Shocks & struts certainly improve the handling, however, be aware that most adjustable struts only adjust the rebound dampening, not compression dampening, which means that even if you stiffen them up, that won't slow down the brake dive on the struts. Running them stiff actually slows the nose lifting on the throttle. (rebound stroke)

I'm running Koni Yellows and UPR/Eibach Pro springs on my car. They work very well together. (very little brake dive)

I think I'm going with this from strano

The steeda ultralights are tempting though.

I went with the Ultralites and koni streets from Sam with no regrets.

let us know if we an help you out, we found the hotchkis springs or even the Eibach pro-kit with Koni STR.T to be a good match and improve ride quality greatly.

Adjustable rebound damping on the shocks will reduce the perception of nose dive under braking.

At least half of the nose-down angle is coming from the rear end rising (rear shocks in rebound). I don't think it a good idea to stiffen the rear shock rebound without being able to balance it with a front strut damping adjustment.

Look closely ↓↓↓ - I'm at just barely below ABS activation, so the braking here is about as hard as it gets on true street tires.

It takes about $1,000 to do suspension right, Norm is right, if you fix the rear without
fixing the front the car is unbalanced, how much? Only an engineer would know for
sure. I am doing BMR rears with STR shocks and see for myself how it turns out.

Call Sam and tell him what you are wanting to do. He'll lead you in the right direction
