Was your ATB worth it? and why
Hi there,
Must be quite a few people with these now, just wondered what the consensus was? have heard from some they don't like them (but not sure why) and from others that they are great.
What improvements did they have and is there any thing you don't like about them etc.
Cheers

Loved mine, improved traction alot. Used to spin from first to third but with the ATB you would get a bit in first and little tiny bit when changing into second hard but was alot lot better and meant i could actually pull away in the rain without looking like a knob.
Also improved handling alot, kinda of pulls you through the corners. Feels weird at first but once used to it was great.

I've found that life I needed.. It's HERE!!
Ive had my atb a year now and it definitely benefits pulling away,dry or wet and you do notice a difference around corners, only if your ragging it tho,the only thing is your always correcting the steering driving along,okay im nit picking but its something i noticed.........

Yes ATB's do it too, sister has one on her RV8 and i quite like it on a rwd car. Just wondered what it was like to live with on a fwd car.
Tim, when you say yours was faster with out it... in what way? were the trans losses higher?

Thats what i thought aswell.
I thought if one wheel loses traction with an ATB then the power is sent to the other wheel. This is why it can cause torque steer, and if say you hit a puddle with one wheel the car will suddenly tug youthe other way as one wheel suddenly gets all the power.

Isnt that is the point of a LSD, if one wheel loses traction it tansfers the power to the other one until it regains traction, and balances back and forth between the two as needed...
I'll let you know soon Rob as i have one in my new gearbox but have not driven it yet!!

A torque biasing diff has to have some load on both wheels. if one is in the air, then yes you will loose all traction to the other wheel.
An ATB will be 100% better than your std diff simply because you std diff is 20 years old and will need the fluid replacing. It will be acting like an open diff currently.

Wouldn't say they're rubbish tbh, but each is own and all that lol!
Had one in mine for a few years now, gotta be honest on the road i find it does tug the car around quite a bit, when overtaking in 3rd for example you've gotta hold on tight but on track they really do make a difference imo, as someone said the diff really pulls the car 'into' and 'round' corners in a much better way than the standard diff that liked to torque steer and make the car push on through bends.
In all fairness if you're just wanting somethin for qtr mile then you're better off getting a plate/gripper diff as the atb is more an aid to the handling than launching. A good fit and forget mod though, mine's survived 2 gearboxes now and given me no grief whatsoever

Rick any idea on who rebuilds LSD's? I guess its a case of whether to invest in an ATB, be happy with a rebuilt (jelled???) lsd or invest in an mtx conversion.

I found the ATB very good on a wet smooth track.
Standard viscus diff is good if not to worn.
My favorite is a ramp type like Tranex or gripper.
I have run all 3, for me the most versatile is the ramp type.

Cost lol, and no that would be the ideal solution, but if i can build a strong standard or ib5 box (strong enough for a reliable daily 200brake) then i am happy not to have the hassle of fitting an mtx75, as i would fit the equal length shafts as well as the box.

Sorry, i pulled my cock out my mouth, typed gripper and rs turbo into google and discovered that gripper/tranex are both companies who supply the ramp type diff lol.
Cheers for suggesting them tho, the gripper seems to be cheaper than the quaife too.
Yours all been fine then crazy cage? large improvement?

I haven't driven my car with the ATB yet, but I had a nearly new ford LSD which CTS "re-jelled" and it was fooking brillient. Round the Hereford - Worcester road on the way to Ford Fair before the engine started playing up I could throw it anywhere.

Happily retired
Fitted one to my 500bhp conversion & set times that would still take some beating for that Power level even now. 0-100 8.1 11.8 quarter & 183.3mph Max. Transformed mine.

Not sure quite what relevance you fitting one to a 500bhp rwd cossie has in regards to the original question......i.e fitting one to a fwd rs turbo with no doubt less than half the power your car had at the time!

lololol, its all good info, but n ATB in a cossy is a bit different to one in an rst. Like i said my sister has one in her RV8 and i really like it in a rwd, but that cant torque steer you all over the road lol. Plus i always think that if you want more traction from a cosworth you may as well do what ford did to get more traction..... drive the spare wheels lol... a luxury unfortunately i can't easily have (or i damn well would lol).
