Are there any lowering springs out there with linear spring rates for our Si’s?

I can't answer your question. But straight rate springs are what we looked for when upgrading the suspension on sportbikes.
I think your on the right track for performance. Especially if your lowering and reducing suspension travel.

Almost all aftermarket lowering springs are dual rate or progressive.
Swift is dual rate (which basically are 2 lineair springs in one) spoon is progressive and others are too.
Only the OEM springs are lineair and most springs on coilovers.
OEM spring are lineair cause they usually have a low spring rate .If you go much higher the springs don't absorb the little bumps much and the ride gets bumpy and harsh.

eibach leans more towards comfort where swift leans more to performance. I do a lot of canyon runs and occasional trackdays. If you want better performance go swift

Swift has the highest spring rate of any lowering springs for the 10th gen.Much higher then eibach.When i'm going to lower my car it will be with swift springs and maybe aftermarket shocks.

a lot of owners here like this springs I actually have this installed on my si as well but am thinking of switching to a little lower spring rate than this one like maybe a ktuned.

I did my research between all the springs out there for our cars. I also settled on Swift due to performance and the subtle 1.1” or so drop. Hopefully I’ll have them installed within the next week or so. Swift makes and dedicated a lot of time and research into their products.
