* Body lift: This raises the body of the car relative to the frame. Even a substantial body lift might not be enough on its own for 26" wheels.
* Suspension lift: This involves modifying or replacing suspension components to increase ride height. This would require custom fabrication or significant modification of existing parts due to the significant size increase.
* Custom fabrication: You'll almost certainly need custom fabricated parts for control arms, possibly the frame itself, and potentially even custom axles or wheel adapters depending on the wheel's offset.
Important Considerations:
* Cost: This will be extremely expensive, potentially costing thousands of dollars.
* Ride quality: The ride will be significantly harsher and less comfortable.
* Handling: Handling will be negatively affected, potentially making the car unsafe to drive.
* Legality: Modifying the vehicle to this extent may not meet local safety regulations. You could face issues with inspection and registration.
* Stress on components: The increased stress on the chassis, suspension, and drivetrain could lead to premature wear and failure.
In short, while technically possible, fitting 26" wheels on a 1995 Buick LeSabre is a very ambitious and impractical project. The cost, complexity, and potential safety risks far outweigh any aesthetic benefits. Consider smaller diameter wheels for a more feasible and less destructive modification.
