What This Product Does:
- In the torsion-bar rear suspension of these vehicles, the torsion bars anchor into spring plates. These spring plates mount to the axle / housing and transmit torsional load into the chassis.
- The spring plates also allow indexing of torsion bar preload and set ride height (among other geometry considerations). By using adjustable spring plates, you gain more flexibility to fine-tune ride height and corner balance without removing the entire torsion bar or axle.
- A good adjustable set ensures that the rear suspension’s torsion bars, spring plates and bushings work together properly so that the rear axle remains located, ride height remains correct, geometry remains stable, and the car handles as intended.
Symptoms Of Wear, Failure Or Need For Replacement:
- Rear ride height issues — one side lower or higher than the other, or difficulty achieving correct height, which can be due to worn or non-adjustable plates limiting the adjustment range.
- Rear handling instability — e.g., vague rear end, geometry shift under load, degraded cornering feel, which may result from worn or inadequate mounting of the torsion bar ends.
- Excessive play or movement at the spring plate mount: the plate may be warped, the bushings collapsed or the indexing mechanism worn, leading to loss of precision.
- Previously lowered or modified suspension — if you’ve changed springs, lowered the car, or altered ride height, the stock spring plates may not offer the adjustment you need; an adjustable set is beneficial.
- Visual inspection: bushings may appear deformed, cracks or corrosion present on plate, plate cover area not concentric around torsion-bar end, or the mounting bolts are difficult/risky to remove due to age/corrosion. (General wear symptoms from spring plate bush kit commentary)
Why Replacement / Upgrade Matters:
- Geometry and ride height control: The rear spring plates are a critical mount point for the torsion bars and ultimately influence ride height, axle location and suspension geometry. Upgrading or replacing them restores full adjustment capability.
- Handling performance: If plates are worn or non-adjustable, you lose precision in tuning ride height or preload, which can degrade handling (especially in rear-heavy or performance-modified cars). An adjustable set brings that tuning back.
- Reduced wear and improved durability: Many OEM plates are decades old; replacing them with modern adjustable units ensures the assembly is fresh, has better materials/finish, and lasts longer.
- Modification friendly: If you’ve lowered the car, widened track, changed torsion bars or springs, an adjustable spring plate set offers the extra range needed to achieve correct setup without undue compromise.
- Value & restoration quality: For classic 924/944 vehicles, using high-quality adjustable spring plates shows that suspension integrity is addressed — which aids usability, performance and possibly resale.
