Yeah, your link definitely doesn't work.

Actually, the 3.55s were offered as an option in the '06, according to my VIN and the window sticker, I have 3.27s. I was leaning towards the 3.73s but everyone seems to love their 4.10s...I wasnt to know if anyone is running the 3.90s ? They seem to be a good balance between street and strip.

 

Somethings wrong here. 3.55 were standard on the 05, 06 man and a $100 option of 07 and $300 option of 08. None of the 05-08s come with 3.27. The other gear option is 3.31. 05,06 verts come standard with 3.31. Take a look at the white sticker on your axle housing. It should give the gearing on it.

 

ok, i will check it out. Thanks!

 

Have you decided on gears yet. 4.10s do pull harder than the stock 3.55s, but drivabiltiy is not affected. Gas mileage may have dropped by 1-2 MPG overall.

 

Brenspeed's gears are Motive, and some folks believe that those may cause whine. It's a part number difference - M versus A at the end.

 

What are the standard and optional gears for the '07 and '08 convertibles?

 

3.31 is standard and 3.55 is optional for the 07-08 models including verts.

 

I think 4.10 will be too much for a car that is getting a super-charger but that's my opinion. I personally love my 4.10s'. Best mod I have ever done.
