Frequently Asked Questions

Find answers to common questions about torque specifications

What type of suspension system does the 2008-2014 Audi TTS use?

The 2008-2014 Audi TTS is equipped with a sport-tuned suspension system, featuring MacPherson struts at the front and a four-link independent suspension at the rear. The system includes adaptive magnetic ride dampers, which adjust damping force in real-time based on road conditions and driving dynamics.

What is the ground clearance of the 2008-2014 Audi TTS?

The ground clearance of the 2008-2014 Audi TTS is approximately 120 mm (4.7 inches). This measurement may vary slightly depending on the specific trim level and optional suspension components.

How often should the suspension components be inspected?

Audi recommends inspecting the suspension components every 15,000 miles or 12 months, whichever comes first. This includes checking for wear on struts, shocks, bushings, and control arms. More frequent inspections may be necessary if the vehicle is driven in harsh conditions or on uneven terrain.

What is the recommended torque specification for suspension bolts?

The torque specification for suspension bolts varies by component. For example, the front strut-to-knuckle bolts should be torqued to 90 Nm (66 lb-ft), while the rear lower control arm bolts require 100 Nm (74 lb-ft). Always refer to the official Audi service manual for precise torque values.

Can the suspension be lowered on the Audi TTS?

Yes, the suspension can be lowered using aftermarket lowering springs or coilovers. However, lowering the suspension may affect ride quality, handling, and warranty coverage. It is recommended to consult an Audi-certified technician before making modifications.

What is the role of the magnetic ride control system?

The magnetic ride control system uses magnetorheological fluid in the dampers to adjust damping force in real-time. This system enhances ride comfort and handling by responding to road conditions and driver inputs within milliseconds.
