Wondering what most of you are using, getting ready to do detroit true trac, and wondering which ones to go with. Mods in my sig. i plan on either ported eaton or 2.3 whipple in the next 6-12mos. Opinions please, and yes i searched.
3.55 or 3.73's

i went 3.73s but should have went 3.27s no track car here
....I thought about this myself! ...Stick with the 3.55's! ...You really do not want more then a 3.55 gear with a Whipple!
gotcha, i am running 3.55's now w/ upper only eaton. i fig. the 3.73's would give me alittle more snap for now. i gotta buy new gears either way, i just got ahold of a brand new center section and i'm gonna set it up now so it's done when i go to do the bushings. Should make it less time consuming. gears are the same price from summit $149 for either set.
Why do you need new gears? ...I would only buy the FRPP Gears (if you need them) ... and get a 8.8" bearing kit! 
which bearing kit should i use?, FRPP sells 4 diff. ones. i need gears so i can pre-setup the whole center section, and wont have the down time of rebuilding it when the full tilt kit goes in. just drop the subframe do the bushings and swap center sections.
the car is a daily driver 22mi to work and back mostly highway, then groceries/errands on weekends. i do make a 3k mi road trip once a year also. Why is my sig. absurd? i do plan to do a few track events, and maybe down the strip a few times to see what it does in june. Whipple 17-19lbs. Havent decided on spray with port yet. Trying to accomplish bushingkit/rear and atleast port by june, whipple depending how funds are.

hey man post your video with your 3.27s for them:banana:
thought about 3.27's also. probably a bad move with stock or ported blower, i'd keep the 3.55's if i went with the 3.73's just in case. i can always change them later.
This kit will work fine: Rear End Installation Kit (8.8in) at AmericanMuscle.com - Free Shipping!
...Doesn't that long to swap the gears from one carrier to the other! :shrug:
nice, i think i need bbk headers and o/r x pipe now too, sounds amazing. sounds like a jet on deceleration. pretty awesome man.
i'd like to stick with one of frpp's kits. i know i don't need the axle seals, they make a special bearing/seal kit specifically for IRS. any part #'s would be awesome. gonna get everything from Summit. working on getting another IRS subframe and control arms, basically wanna build a whole nother IRS drop mine out and install newly rebuilt one with all the goodies.
i just bought M-4010-A88. ordering Detroit True Trac, Gears and install kit tonight, going to bank tomorrow then ordering FTBR kit. still searching for spare IRS.
THIS.:-D LOL Tony!:rollseyes
3.73 is nice open track gear depending on the tracks. Really though once stock power has been exceeded with twin screw power even for open track 3.55s are plenty. We don't use 5th unless we are trying to cool the car down.
If you don't know the length of the straights you will be using, you don't want to hit the rev limiter in 4th. I would stay 3.55s until you know for sure it's not enough gear.
Yeah the sig is somewhat humorous with significantly more detail than needed.
I use a link for my mods, if you want all that info kept I would drop the font to the smallest and try to tighten it up where you can.
i like to have all the stuff listed, it helps others and gives people ideas or becomes a grounds for a new topic or conversation.
M-4210-A,B,C ? which one should i get?
Are you looking to buy an IRS? I know someone here that just went to a SRA in his 03 Cobra.
i'll just stick with the 3.55's then. thanks for the help.
