Limited Slip Diffs

Interesting numbers. Swapping diff ratio's doesn't make quit the difference I had imagined.

Exactly and I'd prefer to have a peacefull cruising engine speed in 5th which is to all intents and purposes an overdrive way out there (on my right) and drive spiritedly with the 'real 4 !

I feel Franky will revert to a longer ratio-ed diff in time....once he's got it out of himself.:D

Fellas, please educate me - what are these telephone numbers you are quoting?

Having had personal experience of the plate lsd I can vouch for the noiseness when hot. As for the understeer this can be dialled out according to your preference.

Is it the same modified stub axles that are needed for the r200 short nose diff?

As far as I am aware the modified stub axles will only fit the Subaru R180 ,I got mine via HybridZ a few years ago but sounds like Sean has some.

Cons of an ATM - not homologated for 'serious' racing.
No but there are "serious" racers using ATB's in a large number of formula series.

For shopping trip warriors a viscous is usable but starts to lose active ability once it gets hot.

I don't like the fact that only one wheel spins during a burnout at the drag strip so I only get one sticky tyre
Odd, my car leaves dual tyre marks on a spin up

yes it can you're right but when you're driving many different tracks then you're constantly tweaking


The plate diff seams to be the preferred choice for those that are experienced enough and have the ability to know exactly how to set the diff for their specific use and be happy enough to keep taking it apart for adjustments.
which involves shimming with expensive and sometimes difficult to get clutch and dog plates

Yes please - I assume it's not nearly three hundred thousand RPMs ;)

Shopping trip warriors rarely get a diff THAT hot unless on drift all the way there....

Maybe it's down to a customer service problem. Quaife tell me it's normal to only spin one wheel when the other has no traction due to sitting in water. Torque is applied to the wheel with traction.

But when you transition out of the water onto the concrete (in order to create friction and heat the tyres) both wheels have some degree of grip so balance should be restored.

The plated ones are quite happy in the back of m3's etc.

Yes but look at the typical demographic that might have an M3

Off piste - did you know that statistically (insurance company stats) the M3 has the most cases of frontal impact of any other car?

Driver attitude or diff lock up under breaking making it misbehave!? :p
