Sparko F8 Rear Sway Bar 2.9mm

The Sparko F8 Rear Sway Bar 2.9mm (SPKF85051-29OP) is a precision tuning option for refining rear roll stiffness and overall balance. Often called an anti-roll bar, this 2.9mm variant helps control chassis roll, promoting a more consistent and predictable feel through fast direction changes and long sweepers.

Use it as part of your suspension setup to dial in cornering stability and traction balance to suit track grip and driving style. Selecting bar diameter is a common way to fine-tune handling alongside spring rates, oils and geometry adjustments.

Tuning Notes

• Thicker sway bars generally increase rear roll stiffness, helping reduce body roll and sharpen response compared with thinner bars.
• Adjust in small steps and assess effects on corner entry, mid-corner and exit to maintain a balanced setup front-to-rear.
• When fitting, ensure free movement and equal link lengths side to side for consistent performance.
