Eibach pro-kit springs for '99+ Miata. Been used with KYB AGX shocks.
I had the Eibach springs and KYB AGX installed by a local performance that works on my car. This combo works really well together. The car is lower, stiffer and much more balanced than stock. I have a very neutral set up and the KYB makes it very to adjust the overall behavior of the car under any condition (street, track, autoX) However, after about 40,000km the front left spring started sagging. It is so bad now that the FL tire touches the spring when turning right!! I now have to buy another kit. KYB are still performaing flawlessly, just one spring is ruining for me. I heard of Eibach sagging when I bought the kit and thought it was just isolated problems. I can confirm this happens for real. I am NOT buying another kit to replace them, I don't thrust Eibach anymore.

Eibach Prokit and KYBs are available from many sources but I opted for Coximport. Good prices off their Hot Sheet and free, fast delivery. Very satisfied.
Installed my self with my son using the "San Diego Miata Club" method. Very slick and not problems. Perfect fit. Purchased new dust boots from Summit Racing. Cut bump stops off the OEM boots and these look great! Too bad they're hidden behind my T1Ss. Front wheels are nicely tucked with no interference.
The set-up lowered the car 1.25 front and 1.5 rear actual measurements. Found that I have to be very observant of speed bumps as some are too steep now. Have the KYBs set to 4 all around but since the ride is not harsh at all (I use my wife as the threshold indicator) I will be experimenting with a higher setting. Expect I'll settle on 5 front 4 rear. Great combination!

Pro Kit, lower 1.5 inches.
Great experience, more than 20K on them.
I reaplced my stock springs with these along with Tokico Illuminas, wonderful ride quality (for a stiff spring), great lowering and highly recommended.
