Boss 302 Springs Worth it?

My experience is that those rates are within the useful range of Koni yellows. Bilstein may have a comparably firm alternative, but probably non-adjustable.

Steeda has a brand-new package tuned for NA S197s (with extensive help from Billy Johnson - a talented Ford W2W racer/development driver/driver coach) that appears to have much the same handling balance as mine. My BMR springe are about 30% firmer than the Steedas, which would soften the ride a bit and require a little less damping than what I'd use on the track (think "more headroom" remaining) Though I think with your supercharger you'd want more front spring than the 200 lb/in that ships with this package (200f/175r).

Steeda 555-2356 Mustang Sport Handling Package (11-14)

I think starting with a call to Steeda and see if they agree that with the exception of front springs that that could be a viable option. Maybe they could substitute their 555-8241 springs instead (225/185).

So fast forward to this week. I got the Boss springs installed along with new isolators and a set of prothane front swaybar bushings. Not a world of difference, but did feel a little more confident taking a few of my favorite turns. Ride doesn’t seem any harsher, but you can see the front is lower now. Has that classic muscle car rake that I like. Only thing is the front wheels look more tucked in than before now that the fender is lower. I have the same size tires as the boss, but my wheels are .5” narrower. So maybe wider wheels at some point. And the snowball keeps rolling!

Wider wheels will probably help a little, but you'll have to balance width increase with offset to get the visual that you're chasing.

Lowering the front without correcting camber back to where it was before typically pulls the tops of the tires inward. But bringing the amount of negative camber back down will add a little understeer back in if that matters to you.
