"Alignment Toe FR & RR" refers to the adjustment of the toe angle on the front (FR) and rear (RR) wheels of a vehicle during the alignment process. Toe alignment is one of the critical aspects of wheel alignment, focusing on the angle at which the wheels point relative to the vehicle's centerline when viewed from above.

Toe Angle:

• Toe-In: When the leading edges of the wheels are closer together than the trailing edges, it's called toe-in. This angle helps with stability and straight-line tracking.
•  
• Toe-Out: When the leading edges of the wheels are farther apart than the trailing edges, it's called toe-out. This angle can improve cornering and responsiveness but may lead to instability if excessive.

Front and Rear Alignment:

• Front Alignment (FR): The front wheels' toe angle is adjusted to ensure proper alignment relative to the vehicle's centerline. Front toe alignment affects steering response, tire wear, and stability.
•  
• Rear Alignment (RR): The rear wheels' toe angle is adjusted to complement the front alignment and ensure straight-line tracking, stability, and even tire wear. Rear toe alignment also influences vehicle handling characteristics, especially during cornering.
•  

Importance:

• Correct toe alignment minimizes tire wear by ensuring that the tires roll parallel to each other and in line with the vehicle's direction of travel.
•  
• Proper toe alignment enhances steering response, stability, and overall vehicle handling.
•  
• Misaligned toe angles can lead to uneven tire wear, reduced fuel efficiency, and compromised safety.
