Tein doesn't market these anymore but a lot of people bought them when they were on the market including me. Nice daily driver set up, but if you've gotten into driving sessions at tracks the springs are too soft - 5K (about 280 lbs) in the front, 3K (178 lbs) in the rear. Tein customer service says you can go with 2K stiffer springs all around without revalving the coilovers. I haven't come across anyone who has gone with stiffer springs without a revalve on these coilovers so I spent $180 on stiffer springs and gave it a try.
Installed 7K (380 lbs), 250 mm length springs in the front and 5K (280 lbs), 225mm length springs in the rear yesterday. Adjusted ride height (center of wheel to fender lip) to 14.25 inches in the front and 13 7/8 in the rear. That's the lowest I could go. Got Noltec camber/caster plates in the front which add about a 1/4 inch of ride height in the front. The car has a Progress adjustable swaybar in the rear and a Whiteline front swaybar.
Got several days of driving in on the stiffer springs. Drove around the local twisty canyon roads that I drive (50-60 mph) on to test the car. Much less body roll than before. Car is more planted on the curves and curves can be taken at greater speeds than with the softer springs. On the interstate going 80 mph the ride was fine - not overly bouncy, jumpy, or jittery. Didn't seem noticeably worse than with the softer springs. When I hit some bumps on the road, the car hopped more than with the softer springs. Maybe a sign that the springs are strecthing the upper limits of the dampers. Getting an alignment tomorrow.
So far I'm in WRX nirvana. I wished I had done this earlier. No regrets with going up to stiffer springs. The real test of the new set up will be the next track session, this time at Buttonwillow. More info to follow.
