Linear Front Springs w/Progressive Rears?

[K-Roll302]

This has been on my mind for a while, but I wasn't really sure how to ask?

I've been running Steeda Sport Progressives for the last 3ish years and I have nothing but positive things to say about the handling and ride comfort for being a daily driver. However (because there's a reason for my question), The front springs have had an issue for the last two years where they'd make noise from the coils touching one another on certain road imperfections, even after replacing the isolators a few times. Maybe they're worn out (Metro Detroit roads...)

This is no complaint to/at Steeda, their customer service and advice is awesome. But I was wondering if this could be an opportunity to change the front springs to something else when the weather warms up? Perhaps their sport linear springs or something else? I like the rear springs as they are and don't wanna change those.

If you run mismatched springs your car will literally explode.

I’m nearly positive the new BMW M2 runs progressives fronts with linear rears—now which combination of rates works well for the S550 is a mystery. A possibility for success I’d say it’s plausible.

Well, no one lives forever, eh? ¯\_(ツ)_/¯

That's an odd setup for the M2 isn't it. I recall reading somewhere the the GT350/R have linear fronts and dual rate rears, or the other way around?

If I’m right, then for sure. I assume BMW went progressive due to the M2’s low stance, and to ensure the spring is well seated in all driving scenarios.

True statement. GT350R rear springs are dual rate.

Perhaps there's a slightly looser handling effect during corner entry (that they'd almost certainly be covering for in the stability control calibration).

Should be a mild understeerish effect.

I've wanted to try this combo for a long time. a Linear front spring and a progressive rear. Getting the rates right shouldn't be too hard if you go with BMR Springs
