Megan Racing Front Upper Camber Arms – 2001–2005 Lexus IS300 (XE10) / Toyota JZX110 Mark II, Chaser, Cresta, Verossa | MRS-LX-0312

Megan Racing’s adjustable front upper camber arms for the 2001–2005 Lexus IS300 (XE10) and the Toyota JZX110 platform (Mark II, Chaser, Cresta, Verossa) — a direct replacement for the factory front upper control arms with adjustable camber correction built in. Both platforms share compatible front suspension architecture, making this a cross-fit application. Essential for any lowered IS300 or JZX110 build: lowering the ride height introduces negative camber beyond the factory alignment specification, and the factory upper arms have no adjustment range to correct it. Megan Racing’s camber arms restore proper front camber alignment, enabling a correct and safe alignment that the factory arms cannot achieve.

Why Camber Arms Are Required on a Lowered IS300 or JZX110

When the ride height is reduced — whether through lowering springs, coilovers, or any other suspension modification — the front suspension geometry changes. The lower ride height pulls the top of the wheel inward, introducing negative camber (the top of the tyre tilts toward the car). On a mild drop this may be within the factory alignment specification’s adjustment range, but on any meaningful lowering the factory upper arms run out of adjustment and the camber cannot be corrected to a safe, tyre-friendly setting. Excessive negative camber causes rapid and uneven inner tyre wear, reduced straight-line braking performance, and handling that is unpredictable at the limit. Megan Racing’s adjustable upper camber arms replace the factory arms and provide the extended adjustment range needed to dial in correct camber — restoring proper tyre contact patch, even tyre wear, and predictable handling on both platforms.

Key Features

• Adjustable Camber Correction: Extended adjustment range beyond the factory upper arm — provides the camber correction needed on a lowered IS300 or JZX110 that the factory arms cannot achieve. Set camber to your preferred specification for street driving, track days, or autocross
• Direct Replacement: Bolt-in replacement for the factory front upper control arms — uses the factory mounting points on both the XE10 IS300 and JZX110 platforms. No additional modification required for installation
• Upgraded Construction: Upgraded materials and construction over the factory rubber-bushed arms — providing more precise camber adjustment and more consistent alignment retention under load
• Street and Track: Suitable for street driving, track days, and autocross. The adjustable camber range accommodates both street-friendly alignment settings and more aggressive negative camber settings for track use
• Dual Platform Fitment: Fits both the Lexus IS300 XE10 (2001–2005) and the Toyota JZX110 platform — Mark II, Chaser, Cresta, and Verossa variants. Verify fitment for your specific model and production date before ordering

Fitment

• Lexus IS300 XE10 — 2JZ-GE (2001–2005)
• Toyota Mark II JZX110 — 1JZ-GTE / 2JZ-GE (2000–2004)
• Toyota Chaser JZX110 — 1JZ-GTE (2000–2001)
• Toyota Cresta JZX110 — 1JZ-GTE (2000–2001)
• Toyota Verossa JZX110 — 1JZ-GTE (2001–2004)

Verify fitment for your specific model, production date, and market variant before ordering — JZX110 production dates and model availability vary by market. A four-wheel alignment is required after installation. Professional installation recommended.
