  4. How to build a car that corners
  5. Compare with standard: Iizuka’s car is above, the standard setup below, showing the modified third link. With an extremely low ride height, the upper arm strikes the top of the wheel housing, preventing adequate shock travel.

  17. Only after going this far did it finally match my ideal. It might be a disadvantage in competitions, but I want to keep taking on the challenge with a Skyline!

  25. Age 30, living in Kaminokawa, Tochigi. Besides this car, he is building a competition-spec Skyline through Koguchi Power, with full body reinforcement planned. He favors the same Nismo steering wheel as his mentor Koguchi.

  29. Remove the weld at the connection to the knuckle, then reweld it approximately 3 cm higher.

  31. …spherical-bearing lower arms. Camber is adjusted at the lower arm rather than the upper arm. Change the tension-rod mounting position: normally it mounts above the lower arm, but the third-link modification pulls it upward and causes contact with the anti-roll bar. A custom spacer allows it to mount beneath the arm. [several clipped words]

  39. A reinforced-bushing version of standard length was chosen rather than the short type. Ikeya Formula spherical-bearing tension rods: setting them to increase caster prevents tire-to-body contact. [bushing wording damaged]

  44. “The Skyline is a difficult car. Even with fully threaded coilovers to lower it, the front upper arm hits the body as the shock moves, restricting travel. Then even a good coilover can’t do its job. I wanted both a low ride height and good driving performance. I considered stiffer springs, but wanted supple suspension. Ikeya Formula took the problem seriously and developed this third-link modification. It creates clearance between the upper arm and inner fender even at a low ride height, allowing the shock to travel properly. The first drive amazed me: it moved so freely that it didn’t feel like the same coilovers. But developing it further revealed another issue: modifying the third link alone also pulls the tension rod upward, causing interference with the anti-roll bar. We changed the anti-roll bar and tension-rod mounting to solve that. For setup, I adjust camber by extending the lower arm rather than changing the upper arm. That gains track width and contact feel, making the car easier to control while drifting.”
  45. 1. Third link: the knuckle-joint weld was removed and rewelded about 3 cm higher. 2. Ikeya Formula roll-center-adjuster pillow-ball lower arms; camber is adjusted at the lower arms. 3. Tension rods moved beneath the lower arms using custom collars to avoid anti-roll-bar interference. 4. Largus anti-roll bar; a larger-diameter bar could interfere with the rods again. 5. Nismo upper arms: standard-length reinforced-bush type, not shortened. 6. Ikeya Formula pillow-ball tension rods; caster set to avoid tire/body contact. 7. Ikeya Formula STC coilovers: standard retail specification, 9 kg/mm springs. These are the article’s modifications, not installation guidance.
