Im looking on the guard Gt1 unit also but if it possible to just uppgrade the stock unit with cup parts that would be a cheaper solution

 

Thanks

I think alot of Gt3 owner that track there car has a bad lsd and don't know about it..I would love to get more info about swaping the plates only

 

Someone suggested to me I reverse the diff too. Didn't seem worth it as I'll just put the cup plates in when it expires.

Like suspension though, I guess this stuff leads a lot of room to ruin the balance of the car, so hopefully sticking with one of the OEM options makes it a little safer.

 

swapping stuff around is much easier when you have two race trucks full of kit and a bunch of bored mechanics wanting to impress....

a crew made up of a borrowed jack, your mate and his girlfriend make this sort of thing much more difficult. especially when she forgot to bring her Mechanix gloves.

I do not understand what you mean..

Balance of the car..?

If it change the balance i will click at the comprssion or the reboun or change postition on the sway bras, or i would change springs, so what is the problem..?

 

Excuse the disruption...

I don't know if this should be the object of a new thread but...: what does it take to upgrade the car with the ONLY goal of making it "balanced" or dependable with slicks ? ( and without braking my bank account ?).

After this talk, I haven't taken a decision on how to fix my gone LSD..

BTW, I have reached - without it (LSD) - my best ever track times...
Which makes me wonder...

 

Cargraphics shocks + Solid bushings and monoball bearing, RS arms, and Cup toe links ?

ANy addition or possible saving here ?

 

So how do you know it's gone, maybe it's just a little lose but not gone

 

I know this is a bit off topic, and maybe not excactly what you GT3 guys are looking at. I do take the chance anyway though.

What is the reputation of Quaife, the have a LSD they call ATB differentail for all Porsches. Anyone with experince with these? I guess its better than no LSD at all. They says they are OEM to AMG Mercedes and deliver both to street and motorsport.

From their website.

The Ultimate Differential

The Quaife Automatic Torque Biasing Differential enables your car to accelerate quicker and corner faster. How?
Simply by getting the power to the ground!

The Quaife differential powers both drive wheels under nearly all conditions, instead of just one.

With an normal open differential, fitted as standard on most cars, much precious power is wasted through wheel spin under acceleration. This happens because the open differential shifts power to the wheel with less grip - along the path of least resistance.

The Quaife differential, however, does just the opposite. It senses which wheel has the better grip, and automatically biases the power to that wheel. It does this smoothly and constantly, and without ever completely removing power from the other wheel.

In cornering, while accelerating out of a turn, the QUAIFE biases greater power to the outside wheel, reducing inside-wheel spin. This allows the driver to begin accelerating earlier, exiting the corner at a higher speed.

The Quaife differential also controls loss of traction when the drive wheels are on slippery surfaces such as ice and snow or mud, providing the appropriate biased traction needed to overcome these adverse conditions. The Quaife ATB differential provides constant and infinitely variable drive. Power is transferred automatically without the use of normal friction pads or plates seen in other limited-slip designs.

The Quaife ATB differential's unique design offers maximum traction, improves handling and steering, and puts the power where it is needed most. A definite advantage, whether you are on the track or on the street.

The Quaife differential is extremely strong and durable, and since it is gear-operated, it has no plates or clutches that can wear out and need costly and regular replacement. There is no maintenance required to the unit, so once installed the unit can be forgotton, apart from the better road responses.

The Quaife differential is great for street driving or racing. Racers don't have to put up with locking mechanisms or spools that tear the steering wheel out of their hands when cornering. Because it behaves like an open differential during ordinary driving, street drivers will have trouble telling it's there until pushing the cars towards its limits.

The Quaife differential is proven in everything from SCCA Rallying to drag racing and Formula 1. It provides autocrossers with such an advantage, it has become "required" equipment for a winning effort.

 

Well, I trust my trustworthy mechanic of my garage......

 

Okey..

I wounder if i can uppgrade my stock unit to a 05 cup unit..?

 

Changing the locking ratios of the diff (cup diff for instance has different ratios) will affect how it behaves under throttle/braking, not to mention the wet.

Not sure what advantage there would be from fitting a Quaife ATB diff? Its not like Porsche haven't done considerable development on the GT3 as a racing platform...

 

Which cargraphic shocks?

 

Now thats what I'd like to have at my disposal. I guess I could if I learnt to drive one of these machines properly

 

Yes i know but i don't still se the problem a CUP one with steel plates will hold longer and work better, the OEM sucks and will be destroy to fast so why fit something that will brake soon again, and if the balance is change it's not harder then change the balance back to your liking
