Parts for your 2005 Toyota Altezza-Struts

2005 Toyota Altezza: does it have struts?

Based on Toyota and Lexus technical literature, the 2005 Toyota Altezza (GXE10/SXE10) does not use MacPherson struts. The factory Toyota New Car Features for GXE10/SXE10, the Lexus IS200/IS300 Chassis Repair Manual (XE10 platform), and Toyota EPC suspension diagrams all specify double wishbone suspension front and rear with separate gas-filled shock absorbers and coil springs. In other words, the shock absorbers damp movement but do not act as structural struts that locate the hub assembly.

Why no struts on the 2005 Altezza? Toyota engineered the XE10 platform around double wishbones to hit handling and packaging targets that a MacPherson setup would struggle to match. The wishbone layout lets engineers control camber gain through the stroke, keeping the tyre’s contact patch flatter in corners for heaps of grip and more even tyre wear. It also separates wheel location from damping, so road shocks aren’t fed into the body structure the same way, which helps ride quality on Aussie and Kiwi backroads.

• Geometry and grip: double wishbones maintain favourable camber under load for sharper turn-in and stability.
• Steering precision: the knuckle is located by upper and lower arms, not the damper, improving feel and mid-corner consistency.
• Packaging: the layout suits the Altezza’s low bonnet line and engine bay, avoiding tall strut towers intruding into space.
• Refinement: separating structural loads from the damper can reduce harshness and noise.

For owners and workshops, this means “struts” isn’t the right part to order for a 2005 Altezza. The correct service items are shock absorbers (dampers) and their coil springs, plus the usual double-wishbone hardware: upper and lower control arm bushes and ball joints, stabiliser links and bushes, and the damper upper insulators. If the ride feels floaty, there’s cupped tyre wear, nose-diving under brakes, or clunks over bumps, the dampers or arm bushes may be tired.

Good practice is to replace dampers in axle pairs and fit new bump stops and dust boots at the same time. Torque control arm bolts at ride height and book in a proper four-wheel alignment afterwards, the Altezza is sensitive to camber and toe settings. Quality gas shocks from reputable brands suit daily use, those chasing a sportier feel might opt for matched shocks and springs or homologated coilovers (noting local compliance rules). On typical roads, dampers often lose their edge by around 80–100,000 kilometres, sooner if the car sees rough surfaces or spirited driving. Regular inspection during servicing—checking for leaks, uneven rebound, perished bushes, and play in ball joints—keeps the chassis feeling tight and preserves tyre life.

• Does a 2005 Toyota Altezza have struts?
  The 2005 Altezza doesn’t run MacPherson struts. It uses double wishbones front and rear with separate shock absorbers and coil springs, as described in Toyota’s New Car Features for GXE10/SXE10 and the Lexus IS200/IS300 chassis manuals.
• What should be replaced instead of “struts” on a 2005 Altezza?
  Order front and rear shock absorbers (dampers), and assess springs, upper and lower control arm bushes and ball joints, stabiliser links/bushes, damper top insulators, bump stops and dust boots. Finish with a four-wheel alignment.
• Can coilovers be fitted to a 2005 Altezza?
  Yes—there are coilover kits that replace the damper and spring assemblies. They don’t convert the car to a MacPherson layout, it remains double wishbone. Choose road-legal options and get the alignment sorted after installation.
