I've had some friends that have run Tanabe stuff on their cars before. They make a good product. These coilovers seem to be like the Bilstein PSS kit and the H&R kit, meaning that you can only adjust ride-height. I don't know the spring rates for the Bilstein's or the H&R kit, so seeing the spring rates for these Tanabe's is nice. Just an assumption I have, the Bilsteins, being more motorsports-oriented would have a more aggressive spring rate. So in the end, as it stands know, it all comes down to if you want German or Japanese Coils I guess.
