--------------------------------------------------------------------------------

i had 3.7's in my manuel vs ute and i think the gears where dodgy to begin with and now there f*ked..now the guy who is going to fix it cant find 3.7's so i have a choice out of the 3.45 or 3.9,any opinion's welcome..but jst worried that 3.9's will be to high of a ratio?let me know what you guys think..cheers

3.9 is a lower ratio than 3.45.The lower the number,the higher the ratio.

[grundy303]

yeah i know that dude but i mean will i loose to much top end with the 3.9's or maybe even pretty much have no 1st gear? 3.45's might be the best of both worlds

[Brett_jjj]

Id go the 3.45.especially if you do a lot of highway driving.If you just wanna leave one hell of a burnout at the traffic lights,then go the 3.9,it will give excellent takeoff/pickup,but will loose top end.
It mostly comes down to how you use the vehicle.Highway or around town/city driving.With the 3.9 it will rev fairly hard at 100 ks.Is it auto or manual.

I have 3.45s in my manual clubby,and is a good compromise for highway/town driving....
Very happy with them.

but yea,depends on what you want them for...if you are a traffic light warrior,get the 3.9s....

[grundy303]

its a manuel and yeah mostly jst driving round town but somtimes on on a free way its a bit of a toss up,up to bout 80 should the revs be alright?well really i jst want to know if the 3.7's will be much different to the 3.9's?

[immortality]

i'd go 3.45's especially if it has the getrag box which has a 0.8:1 5th gear Od ratio instead of the 0.72:1 5th gear that the T5 has.

3.9's and 4.11's should be reserved for auto's or cars fitted with a T56

alright boys i have to make a decision as of today i dnt do much free way driving but do sometimes,im prob leaning towards the 3.45's but was waiting to hear anymore bout the 3.9's in a 5spd v6 if there any good and also if they are easy to wreck?

i have 3.9s in the ss with the t5 and i dont mind it. not the best for highway cruisng at 120km/h but the boogie off the line and id rather acceleration over top speed
