Rear Lower Arm Adjuster (Patented) — Toyota Supra (JZA80)

The Rear Lower Arm Adjuster (Patented) — Toyota Supra (JZA80) — an Ikeya Formula chassis-geometry component for the Toyota Supra (JZA80), machined and finished in-house.

Brand: Ikeya Formula
Product Name: Rear Lower Arm Adjuster (Patented)
Fitment: Toyota Supra (JZA80)
Part Number: 723

Note: Many Ikeya Formula components carry a Japanese patent (PAT.). Fitment should be verified against the specific chassis sub-model before ordering, especially where options list facelift / pre-facelift or power-steering variants.

Ikeya Formula’s suspension range is a reference point in Japanese chassis tuning — pillow-ball tension rods, adjustable camber upper arms, roll-centre correction kits, HICAS tie-rod replacements. The parts are machined from billet and finished to a standard that stands up to full-time circuit use. Each is sold for one specific chassis, so the fitment is tight rather than generic.

Features:

• Chassis-Specific: Machined to the exact mount geometry of the Toyota Supra (JZA80).
• Billet Machined: Produced in-house at Ikeya Formula; no outsourced generic parts.
• Pillow Ball or Bush: Where applicable, choose the variant that matches your car and use case.
• Patented Where Marked: “PAT.” in the title indicates a Japanese patent on the design.
• Circuit-Grade: Built to hold geometry under track loads, not just street alignment.

For Toyota Supra (JZA80) owners refreshing suspension bushes, correcting roll centre on a lowered car, or converting to pillow joints.
