Hello everyone, I'm new to the site. My name is Jesse. I have a 2003 G35 Coupe 6 speed. My speedometer reads 10 mph faster than what I'm actually going. Any ideas on what it is?

 

Check all your ABS sensors are plugged in on the back of the wheel area (white plugs that are quarter sized. Also, what are your wheel sizes?

 

Wow, 10 MPH over is excessive and has nothing to do with tires size unless you're running 13" wheels. Don't believe tire stores would have sensor readers for your ABS sensors so take your coupe to Nissan. They're way cheaper than the Infiniti stealerships and will be able to correct your speedometer issues...Gary

 

Ha, I had a buddy follow me and I hit 40 before he hit 30. So my sensors are going bad? That sucks. I've already put $5,000 into the engine just to keep it running.

 

I've been trying to find some stock bumper covers and side skirts, anyone know a good sight?

Tbh abs sensors are not worth it. Find some off a junk car if that is for sure your issue.
