Adjusting your Lexus IS-F suspension with a performance upgrade can result in better handling, giving you an edge over the competition.

So, while the suspension and handling might pose some issues, you can overcome them with the right modification.

Regular maintenance, such as timely oil changes, can prevent further brake problems. If you’re interested in upgrading your brakes, consider using Brembo parts for enhanced performance.

Always consult car problem resources for DIY fixes or contact a professional for vehicle maintenance to ensure your Lexus ISF braking system remains in top condition.

Exhaust and Intake Systems

Your Lexus ISF may experience some issues with its exhaust and intake systems. One possible problem could arise from the headers, affecting the vehicle’s exhaust sound.

For better performance, consider the K&N Typhoon Intake System, which has been shown to achieve 375 horsepower with a simple intake installation.

When dealing with these systems, maintain open communication with your dealer and stay on top of routine maintenance. By addressing specific problems as they arise, you’ll ensure a smoother ride for your Lexus ISF.

The estimated repair cost over a 5-year term is about $3,500, which is significantly lower than its competitor, the BMW M3.

While there aren’t any notable funny complaints, you might come across some discussions about its slightly harsh ride and squeaky brakes, which are common in high-performance cars.

However, these aspects seem minor considering the overall quality of this Lexus model. You can always check out reviews from fellow drivers for a comprehensive understanding of the ISF’s performance and reliability.

Dealers and Maintenance

For proper care of your Lexus ISF, regular maintenance is essential. Dealers and other reliable service stations can help with oil changes, tire rotations, and brake checks.
