RSR's Down-Sus or any near-compatible OEM replacement style lowering springs of mild nature is fine for visual aesthetics. It will not alter the suspension too much since the harder rate they are designed with is only for reducing the suspension travel when things are lowered on stock shocks. Since lowering a car on stock OEM shocks, will effectively reduce the working stroke range of the suspension, we simply need slightly stiffer springs to make it work in that shorter range of motion.

Will it improve handling? Well yes and no. It will improve the driver "feel" of the car since the initial response for feedback is more immediate. However in real-term performance, it isn't going to change very significantly and we do tend to lose a little in the comfort department since we are not touching the character of the shocks, and simply changing a spring out will cause a very slight mis-match. So thnk of spring upgrade as a sacrifice in slight comfort and gain in visual appeal, but not really up or down on the performance aspects. True "UP"grade doesn't happen with small and individual parts changes, but more drastic and complete make-over with combination of higher grade mono-tube shocks wrapped with coil-over piston/case adjustable (as in RSR Sports-i) and some links and arms to recalibrate the entire car at the new specifications and going where parts list constraint couldn't do with $25,000 limit on sticker price initially.
