J'S Racing S2000 - Suspension Shootout

Ride Quality
As one of the most noted JDM Honda tuners, J's Racing was the early front-runner to appear with the stiffest suspension, tuned for the pristine race tracks of Japan. Surprisingly, this suspension was smoother than the CR, with a freeway ride quality close to the stock AP2. There was some harshness when going over multiple small bumps and it was hitting the bumps noticeably harder than both stock S2000s when going over sharp imperfections. Still, the only suspension shipped from Japan came out feeling very un-JDM.

On-Track Behavior/Lap Time
Hello, can someone do some basic maintenance, please? Engineering Editor Chen found this donor car to represent J's Racing and personally set the car up the night before. The slipping clutch wasn't helping it get out of the corners and the fading brakes weren't helping it get into them. More than once, Hope had to trail-brake into turns because it wouldn't slow properly. This would invariably send the back end around. In the sweepers of sectors eight and nine, it wasn't any better. The lack of downforce, combined with excessive body roll, made for some pretty flashy racing lines. The car was nearly a second off the pace of the CR, but we can't help but think it could have done better after a 60K-mile service.

Damping Quality
This suspension was smoother riding than the CR and felt close to the stock AP2 on the street. There was some slight harshness over sharp bumps, but the J's Racing kit left Kojima thinking that this was how a good OEM calibration for a sports model should be. Trackside, the J's Racing kit was firm, with good body motion and platform control. The feel was decidedly more European than the other JDM suspensions, with a style reminiscent of KW, except with slightly less damping and firmness. The kit understeered slightly on turn-in (on the track) but had good balance and good exit traction. This was Kojima's favorite Japanese suspension.
