The BEST thing you can do is get the LSD rebuilt with motorsport plates and 40/60 ramps!

Its night and day better! The car is SO much more planted on acceleration and the instability on heavy braking has now gone!

Bang-for-buck the best mod you can make!

... Here ends this public service announcement... thumbup

Who's ramps did you use, I've got guard internals in mine set at 40/60 ramps. The way the car rotates in sharp corners is a real eye opener;)

Cunno it was rebuilt by JZM using parts from Gt Gears. It truly transforms the car doesn't it.

Amazing machine.

Mr Demon, it feels spectacular with the passives and the rebuilt LSD. You should get one! biggrin

Would love to but I am never free on weekdays, especially Mondays frown

Just has an awesome weekend in Wales though, passives and the LSD worked beautifully together.

All-in-cost (including fitting and fluids etc) £1900 This is for the motorsport plates and the 40/60 ramps.

Diff price is above and shocks were around £2500 fitted.

If you are going to do both then I highly recommend getting the LSD done first and then the shocks and geo as obviously the geo may (will?) be affected when the LSD is removed and refitted.

Can i ask about the downsides of the new LSD? If it's that great, why did it not make it to the road car?

same reason passives don't or monoball rear toe links etc etc.

people love OEM but one can always make a car much much better, just it seems many in the UK don't, and say "Porsche knows best" and end up driving an unsteering mess !

I never know if to laugh or cry at peoples cars on here who stay oem for ever but say they are true car nuts !

It's great to see a car fan make changes and enjoy the car.

I can't see any downsides so far as my existing diff was shot. You may see a little more front-end push depending on your driving style but the 40/60 ramps are relatively benign and turn-in is not adversely affected (for me).

The original diff was a 28/40 ramp, which quickly changes to an open diff once you do a few trackdays as the plates are relatively poor quality. The Motorsport diff plates are steel with a plasma coating. The standard diff plates are brass.

I guess Porsche thought an electronic application of the rear brakes would make a good (crude?) replacement for the poor standard diff!

All depends on the Marque as to the attitude to OEM or not, many Porsche owners tend to be blind to the world of modified cars...every now and again a 911 owner gets the shock of his life from a modded Ford, VW, something Japanese etc and just can't accept it lolbiggrin

In my view there is a down side, and that is with the bigger ramp angles and beefed up plates the car will push more at the front end in tight corners this comes more apparent on wet tarmac.. in the dry there is enough play on the sway bar settings to stop this but on a wet track I haven't been able to dial this out yet.
