Finally took the time to swap pumpkins. 4.083 FD gear came from a '07 HR Z. The process was actually much simpler than I had initially expected. Couple bolts off the axles (10), drive-shaft (4), and one vac line later, the new pumpkin was in . I unfortunately didn't get a chance to open her up much, but will in the morning on the way down to campus. By the way, the pumpkin's pretty freaking heavy! Caught me a little off guard .

So now, we all KNOW that the rear pumpkin off a 2007 HR Z will indeed bolt DIRECTLY up onto a 37's. The only problem we had were the sensors. Fortunately for us, we were able to retain the individual harnesses per each car (Z's merges, while ours splits off into 2 individual lines). The ABS sensors came right off each pumpkin.

4.083 Rack and Pinion OE (Nissan Pathfinder - forged thicker for towing). Shimmed, upgraded seals and bearing. Chatter free!!!

(2010 G37S 6MT)

 

Should be noticeably faster...3.69 to 4.08 is a good step up

 

ring and pinion - not rack and pinion... its rear end gears not steering

 

ooh, but what if it was RAS

 

^^^ only thing I can think RAS means is rear assisted steering?

 

I'm literally...speechless. LOL thanks for lookin' out OCG!

 

How much did you pay for this rack and pinion gear? LOL
srlsly, how much?

 

RAS = Rear Active Steering. An available option on the G37S I believe.

I was just joking about having a "rack" out back if it had RAS.
