This link mentions 4.27 axle ratio for 1999 GS300. Does it mean gear ratio, or is it something else. Please educate me...

same thing

AZ-GS300

Axle ratio is the gear ratio of the differential.
Gear ratio usually refers to the gear ratios of the transmission.

So, does that mean 1999 GS300 has 4.27, not 3.92?

AZ-GS300

Is the 4.27 a typo? I know things change from year to year, but my brochure says the 98 GS300 was 3.27:1 while the GS400 was 3.92:1. Or is the typo in the brochure?

lalexusgs

More like a brochure typo, 'cause I think people mentioned here that GS400 has 3.27 (many replace it with the 3.76 one) and GS300 has 3.92. But that link says 4.27 for 99 GS300

AZ-GS300

Now that makes it even more confusing. Where does the 3.76 come from?

Supra TT rear....or from Carson brand new (I think)

lalexusgs

Not sure...I think from Supra, or some aftermarket factories produce it. Other CL members can explain much better than me.

the gs400 has 3.27 stock
the gs300 has 3.92 stock
the supra tt unit (or the rmm, which is just a rebadged supra tt) is 3.76

but here it says 4.27 for 99 gs300? i don't know, that high? from what i know all gs300 has been using the same rear end

lalexusgs

Yep, that surprised me too, 'cause everyone here said that GS3 has 3.92. Edmunds seems to be pretty reliable source, though. So, I don't know...

i am too lazy to check, but what did they say about 99, and 00+ then?

IAGS400

Agreed, that is what my 1998 brochure says.

lalexusgs

I don't know. Didn't find anything on other years, just 1999 showed up their driving test.

AZ-GS300

There has to be other people with different year GS brochures out there that can post what theirs say about final drive ratio....
