astro932 · 01-01-2017, 08:36 AM

so question, does srm still work? and does it mess with the speedo?

masons169 · 01-01-2017, 08:43 AM

yes it still works. i think its off just a touch, but not really noticable.

Speedometer should be dead on with factory diameter tires; as the speed sensors (2) are located on the output stub shafts...they read it there/ so 3.36,3.69,4.08,4.36 shouldn't change speedometer.....not sure about other features.

Except 370Z's are out by about 10Kmh at 100Kmh. My speedo reads 100Kmh when I'm going about 90Kmh.

That's 10% (6.2mph) either you have put very short tires on your ~Z~ or something else is going on....mine is near perfect with new rear tires (26.8,26.9") but as they wear down,you can get 1 to 1.5mph slower than readings of speedo....only 1-2%.
You may want to have something looked at/as i haven't heard of one being that far off.
