I will definately post up reviews if I get my hands on one of those, I just hope I wont NEED a new diff anytime soon.

Out here where Im living at now seems like I will probably have to order it online.
hmm maybe its a typo on his web site..i found non NS in 80w140....

Thanks I'll be sure to pick up the 75w140ns before my next track day!

i think if you've got the TRE ure set for.. i mean pretty much years.. but when jon looked at my cusco and some other full aftermarket diffs, he pretty much said there's a reason they cost as much as they do and that his is the budget bang for the buck kind of deal

i think i spoke a little soon, the cusco is still banging here and there, though less than it did with the severe gear. that said i may put severe gear back in the t-case, had an odd noise come up that i'll post about later

overall I'm getting much less noise with the OEM diaqueen for my Cusco - Cusco actually recommends dino, and I think it just plain prefers the dino straight 90 or w/e Diaqueen is. Will see how it is on the next change

does my european evo need a 12 plate upgrade
Hi, guys.. I have a question about my European evo ix. Does it need a 12 plate upgrade especially I often go to track... although i have front lsd upgrade.
What is the big difference about EU and US evos about that
I have intent to upgrade with ACD-tuning soon too

does anyone have any experience running a wide body kit along with the acd re-flash and dif upgrade combo? im planning on doing both upgrades with GTworx springs , whiteline FSB and RSB and maybe later down the line a voltex wide body kit with some 17x10's..im wondering if the wide traction will help or just be overkill.

How much power is your car puttin down? Im at ~300awhp on a mustang dyno and I find my 18x9s with 255/35 star specs to be just great for track duty.

I've read the technical difference among 1, 1.5, and 2 way diffs. Can anyone point me to any explanation of how exactly the car will react on deceleration entering a corner, going from a 1 way to a 1.5 way rear diff? Assuming plates/arrangement the same otherwise.

can you plz help me: last spring I bought RS, and I did intsall it (originaly I had AYC car Euro Evo8), but the point is that when I spin the drivers side wheel forward the passenger side wheel spins back, so I have to adjust the rear diff. How many torque should I apply for the diff or what should I do for both wheels to spin forward but do not click


thanks
