Title says it all

 

only sedans equipped with the sport tuned suspension package and all 6MTs.

 

"Starting in 2004 a VLSD rear differential was provided with the 6MT."

 

I think it's 6-spds only.

 

RWD 5ATs with sport package came with a VLSD, at least the 05-06 did, not sure on 03-04.

 

check to see if you have red shocks which means you have sport susp. Then i think you should have lsd.

 

From freshalloy (no guarantees regarding veracity):

2003 G35 sport sedan = no VLSD
2004 G35 sport sedan 6MT =VLSD
2004 G35 sport sedan AT = no VLSD
2005-2006 sport sedan = VLSD (I presume that includes AT)

 

Hey Antonio, I have vlsd... ask me how i know...

 

I have it. 05 sport package. 5 AT.

 

I have an 06 5AT non sport, but I can still lay down dual strips. Doesn't that mean I have it as well? I've wondered about this since I bought the car.

 

not always an open diff will lay two patches if you get a break tq going at a good speed if you just brake tq it a bit and then punch it and then look at the marks the right side might be a lot darker which usually = open dif. You can also put the right rear tire in grass and floor it if it keeps spinning and the rpms are shooting to redlline that is a open diff.

 

Open diffs can leave two stripes too.
