Ikeya Formula Front Tension Rods (S13 / S14 / S15)

The tension rod locates the front suspension fore and aft. Stock bushings are soft for comfort, so under high G they flex, causing toe change under braking and vague feedback. Ikeya Formula replaces the bushing with a pillow ball (Pillow type) or reinforced rubber (Bush type) for a stable corner entry, and the turnbuckle lets you adjust caster and wheelbase.

Adjustment range

• Pillow type: -26 to +20mm
• Bush type: S13 -14 to +10mm / S14·S15 -20 to +10mm

Not compatible with the factory air guide panel.

Sold as a left/right set.
