Honestly, the SP001 is much better suited for a daily driven car where ride comfort is priority over absolute lateral g's
on a scale of 1-10 how would you grade the ride quality of each set?

This is very subjective, but with my experience I would rate as follows. With 10 being the smoothest and 1 being the harshest, I would rate the standard SP001 springs around an 8 and the SP090 around a 6. But if you look at cornering confidence and stability the numbers would be switched

Boy, I dunno. I won a lot of stuff without big rate springs. I have never seen the need to go there. This includes on my own cars, where I ran against many, many cars with stiffer springs of all sorts and I wasn't the one who lost.

I'll gladly send you a set of ours to test if you'd like

Would the combination of SP001 fronts and SP090 rears get me a 7 in smooth ride and cornering confidence? Also, earlier in this post I noted I had welded LCA's. I was wrong. I have Metco bolted LCA's along with welded SFC's and STB from BMR. So I went to your site and now I'm interested in the lowering package with relocation brackets, springs, and PHB.

Thats not how it works at all, why would you want to mix springs?
The front and rear spring need to work together, if you have the stiffer 210lbs/in rear spring and the softer 550 lbs/in front spring the car will want to heavily oversteer. If anything it would be safer for you to have the stiffer front springs and softer rear, so the car will understeer, but this does not improve handling.

If those LCA's have poly bushings on both end they are not helping your handling or ride quality situation. Ideally for ride rubber is best, but rod ended is better for handling, doesn't bind like poly can.

I asked because I see they sell fronts and tears separately.

I agree with JD (won't see me type that very often lol). The imbalance of spring rates would cause some very undesirable ride quality and handling aspects. It is important to keep spring rates in relation to each other front to rear. keep in mind, the rear is more sensitive to spring rate change than the front due to the mounting position and weight distribution of the car. So going up that much in the rear without changing the front would be much more noticeable than going the other way around

I bought the 725s just to see what they would feel like because that would have been the only way to try a stiffer spring and not switch to coilovers. I had some 200 Afco springs already. I was kind of doubtful that they were going to be streetable, but they are VERY streetable. Dare I say my car rides just as good as the 550/175s that I had in there before. And I have Koni SAs and the fronts are set on 5 from full soft. My backs are on 1.
