Looking for help on rear coil springs

My rear coil springs broke on my 2011 Mazdaspeed3 and I ordered MOOG 81693. The mechanic says they are longer than the stock ones. Rock Auto lists the alternate part number for them as BBN628011D. I called Mazda and they gave me BBN628011D as well.

Finally, my mechanic asked around and found out that the stock springs are indeed specific. It seems that most websites offer BBN628011D but those aren't actually Speed3 springs, just normal Mazda3. It seems the ONLY option is to buy them from Mazda for $300.

So... it looks like I either put in the ones I bought but the car will sit about an inch higher in the rear, or I spend $300.

Any thoughts on if all of this is accurate, as well as advice? I don't care if I lose a tiny bit of handling, I don't race the car and spend more time with my daughter in the back seat than not. Will I care if the car sits higher by an inch? Are there any other side effects I should be concerned about? Someone on Reddit suggested using these could damage the bushings or other parts of the suspension?

I'd prefer not to spend $300 (on top of $1000 of the rest of the repairs I need) unless I really need to right now.

Thoughts? Clarifications? Advice?

The different spring rate might accelerate wear on other stock components but I don't really know for sure how big of an issue that would be. If you can return that set for a refund, you can pick up aftermarket MS3 lowering springs for probably like $200ish.
 
You should be fine.

The spring rate or length is not that much different where it will damage your suspension at all, I don't know who told you that shit.

If anything it'll give you a higher rake in the rear, which you may like when driving. Not to mention that you'll be able to load up the hatch with more groceries before it droops real bad.

Nice, thanks!

Or the 100 lbs worth of tools I keep in there at all times because I never know if I’m gonna blow a coupler off my intercooler boosting up a mountain on the way back from Indianapolis. LUL
