There is one front-end clunk over pothole edges and driveway lips, but larger smooth bumps do not reproduce it. How would you isolate end links, strut mounts, control-arm bushings and ball joints? Mi…
2013 Infiniti G37 xS, about 118,000 miles. On repeated pulls I can feel the car soften as temperatures rise. Would you prioritize an intercooler before adding more boost, even if the current setup is…
