If it works well, why are you considering spending money on aftermarket springs? An experienced racecar driver can detect small suspension changes, but, unless you're a very serious autocross driver, I wouldn't think you'd gain anything.

And this I find very hard to believe! Rate errors arise from 3 sources: deviations in wire diameter, coil diameter, and number of coils. Specifically, it's 4 times the ratio of wire diameter error to wire diameter, 3 times the ratio of coil diameter error to coil diameter, and the ratio of coil number error to coil number. Any one of these factors can exceed the 0.02 value, but, if you're lucky, they can cancel one another. So, if the spring supplier tests and tags every coil in a lot, he can probably select coil pairs that are within 2%. But, is he going to eat those for which there's no match? I doubt it.
And, even if he did give you a coil par that is within 2%, there's no guarantee that the next pair will be very close, though they share the same part number.
