Question Final Verdict On Aftermarket Lowering Springs

I'm in my final stages of completing my must have mods and I'd very much appreciate helping a brother out in deciding which aftermarket springs to go with. I've done an extensive search and came up with the following:
  1. H&R
  2. Eibach
  3. RDSport
From you're personal experience, which springs are the best in looks, noise less, and handling. Which vendors would you recommend? Thanks in advance.

Modifications:
  • Engine: RPi / PC Stage 2 ECU Software, RPi ST Underdrive Pulley Kit, RPi Ram Air Intake Kit (Black) & Block Off Plates, RPi SV1 Oil Cooler (Black), M-Sprint Booster
  • Exhaust: RPi GT Headers, RPi Hybrid X Pipe Section 2, RPi GT Section 3
  • Exterior: Vorsteiner CF Vented Hood, RH Type CF Splitter, Upper CF Mirrors, CF Side Skirts, CF AC Schnitzer Style Trunk Spoilers, CF Side & Kidney Grills, Black Powder Coated Lower RaceMesh Grille, CF Pillars, all Roundels in CF, Red Angel Eyes, OEM Smoked Tail Lights, Smoked Side Markers, Brake Calipers Painted in Red with CF ///M Decal

DOUL -- you read my mind! I was about to start a thread about the longevity of lowering springs. I was just going to ask specifically about H&R, but nonetheless, looking forward to hearing about this...

Too bouncy and handling suffered. Different springs may yield different results. I was using RDSport before I switched. My conclusion was that the springs did not match the dampening of the OEM shocks and that maybe Eibach would have been better, but I did not like the way it sits on Eibach. The ride and handling on KWV3 is incredible and even better than stock and my KW's are set very very low. I felt like I destroyed the handling and the ride with springs and the KW's did the car justice...

Just my opinion as others have been very happy with springs...

Eibachs retain the OEM feel of the car while lowering it for looks.. The spring rate is a little soft but not much different from OEM... H&R's are a little stiffer, if you are looking for handling i think they are a lil better as you can "feel the road" better, but if you are into smooth rides then I suggest he eibachs...

2004 Mini Cooper S: Alta supercharger 15% pulley upgrade, Dinan cold-air intake, Skunk2 header back exhaust, RMW CUSTOM TUNE, Alta oil catch can, OMP Strut brace, Eibach pro-kit springs, H-Sport camber links, 19mm Rear sway bar w/ adj. end links, 18 in. Breyton mini magics, 6lbs lighter crank pulley, polyeurathane tranny and engine bushings, wheel Studs, Wilwood BBK... More to come soon!

RIP=White 944 turbo: KKK K-27/6 turbo, upgraded intercooler, Lindsey Racing hardpipes, Autothority MAF, B&B exhaust with 4.5" oval tip, Siemens #55 fuel injectors, Lindsey Racing MaxHP custom Chip set, 3 bar fuel pressure regulator, Re-worked head and slightly overbored pistons, Spec Lightened 6 puck stage 3 clutch, Quaif torque biase differential, Apexi AVC Type-R Electronic boost controller, HKS type-1 turbo timer, Shimmed wastegate, Champion Motorsports adj. bypass valve, Weltmeister front and rear sway bars, Weltmeister strut tower brace, Koni adj. "yellows", unknown springs, Turbo Twist rims, Kumho Ecsta Supra tires... And a couple of more unknown mods...
