my next mod i am saving up for are a set of gears. i heard alot of talk that the 4.08 gears are very diffcult setup. i am planning to have it installed at a well known performance shop near my area. is it worth getting the 4.08's or should i get the 3.9 and stay save?/

 

4.08's are cheaper....both equal in terms of installation. If your redline is 7000+ I say 4.08's, but if you are limited to under 7000 3.9's might be better. This is only my opinion....based on the fact that 4.08's can require a shift to 5th in the 1/4 mile. If you are basing this on "street" performance or circuit racing than the 4.08's will shine.

 

love my 4.08's!

 

Be aware that 3.9 gears are significantly more expensive becasue of limited production.
Most will recommend going 4.08 regardless.

 

4.08s your first gear its pretty damn quick, and normal street driving is +1 gear now.

 

I love my 3.9 fd

 

LOVE my Four-0-eightS

 

what gears does a base model 2007 z has?

 

3.5 for 6mt

 

i have a 06 mt w 31k w no vdc.. will this setup be ok for a set of gears to be daily driven.

does anyone know the average price for installtion on a set of gears?

what about 3.9 or 4.08 with a turbo?

 

I would go with 4.08s

 

install costs will vary by shop, but expect to pay $400-$600

 

are 3.9 & 4.08 used on n/a.. do they would well if i decided to get a turbo

 

it would depend but generally speaking, no

 

wow!im lucky my mechanic is only asking for $150-200!

 

For that price.....................................he better be good.

Ring and pinions are a VERY tedious install and definetly require someone that has done it before, pref quite a few times.

Hope your guy knows what he is doing....

Instances of shops fuking up installs on the F/Ds are a dime a dozen, brosef.

 

I hope you are also lucky that they have done it right by measuring the gear back lash and preload.

 

Went with the 3.9 on the HR, paid around 500 installed.

The install should not differ between a 3.9 or 4.08. Same process just different gearing.

Might want to look into finding a pumpkin with a 3.9 or 4.08 installed already, it might be cheaper and you'll have your 3.5 to swap back in when you go TT.

 

i think he knows what hes doing...he installed my previous 3.9fd and couple of my friends.

 

Man, if joesph is charging only that much, I know where I'm going. But he is good tho.
