In late February I plan on running my G at the track and I have a set of 225/50R15 drag radials I'll be using. Yes, the rims clear the calipers. The drag radials are 23.8" tall and the stock 215/55R17s are 26" tall so the DRs are about 9% shorter than the OEM setup technically giving the equalivant of a 3.66 gear vs the stock 3.36 gear. I'll be running the OEM setup in the front which means the rears will be spinning faster than the fronts. I plan on turning off the traction control, but I'm concerned about the ABS and also the tranny because the shorter rear tires will throw the speedo mphs off. Does the tranny use RPM to determine shifts or MPH? I'm assuming RPM determines the shift. Those of you that have dynoed, does the ABS light come on when you dyno?

 

ABS, VDC off and Slip light stay on for a minute till you drive the car a little ways, same thing my maxima did. If you decide to pull the fuse in the engine bay by the battery the ABS is completely disabled.

 

Wow that's a pretty tough question. I think this is something that a Nissan tech would have the best bet at solving. You should try posting the same question over here:

in the Technical Forum. You should be able to get a quick and informed response.

Good luck and please post their response to the question here too.
