I brought a set of Tanabe Sustec Pro SS coilovers from Azjs. This is by far the biggest and most expensive suspension modification I have ever done to any of my cars.
The damper is 4 way adjustable and is also height adjustable. The front spring rate is 10kg/mm and rear is 6kg/mm.
The assembled front strut, I didn't opt for the pillowballs so I had to reuse the top spring mount. You have to trim the collar off the stock rubber spring mount to fit those lovely billet alluminium Tanabe mounts.
Its set fairly low (Azjs your naughty boy, your car must be so bloody low, I had to raise the spring perch 7mm)
It was a ***** of a job to get the stock rear strut out of the car. But with a pair of spring compressors to shorten the strut, it came out no worries.
Assembly was easy and so was the install. I set the rear perch 14mm up and bang, it was perfect. The car has a 8mm forward rake, which is a bit of anti squat and pretty close to stock. I left all 4 dampers in #3 (75%).

The ride height
Driving impressions? From a short drive, the ride is surprisingly comfortable! The is less pitching and bouncing. Cornering is MUCH flatter. The car is generally much more responsive to steering input. Weight transfer fore and aft is well controlled.
And nothing went clunk and fell out!

The car looks discrete and still won't attract any unwanted attention.
