Does an LSD made a noise like ABS when its working?

ginashamz

I have noticed a clicking sound on the rear brakes whenever I go fast around round abouts, similiar to how ABS feels. This is the LSD or something else?
Also, as I have a RWD car, I have some Runways Chinese tyres on the back with good tread. They have a hard compound and should last a very long time. Is it sensible to run these tyres? My front tyres are Bridgestone with 50% life left.

No expert here but I've read people suggest the rear tyres should have the best grip to avoid e.g. the rear end breaking away in the wet. Hard compound usually means lower grip.

An LSD in good working order will be silent in operation.


Runway tyres are OK for non-sporty applications (I had a set on a Series Land Rover and they were fine) but for anything sporty I would replace with something half-decent.

To be honest I am still surprised at how much grip the car has even with these hard compound Chinese tyres at the back. I can feel the LSD working (at least it feels like the LSD kicking in) at around 30 mph around the round abouts. On the wet however totally different story, I do not feel at all confident to take turns at a decent speed.

May on the dry the Chinese tyres make it easier for drifting :rotfl:

So exactly what car is this with a LSD?

I thought that the various forms of Traction Control had replaced LSDs these days.

If you take LSD you may hear all sorts of sounds, and the walls might start melting as well.

It's a RX8 PZ. Apparently it has a super torsen type LSD.

Probably whatever Mazda are calling stability control nowadays.
My Renault Nee-San calls it ESP (Electronic Stability something beginning with P that I can't think of now).
Basically it has yaw sensors and a steering angle sensor, so If I have full left lock on and it isn't yawing to the left it bangs the left hand brakes on and tries to drag it around.


I run Chinese ditchfinders on the back, as the back wheels just keep the boot from dragging on the floor, and I have ESP and ABS to keep the back end in line, but you shouldn't as the RX8 uses the back wheels to put all 200+ BHP onto the road, as well as stopping the back end overtaking the front, so you need as much grip as possible at the back.


What will happen is the throttle and spark will chop back to stop the back end overtaking the front, and if that can't stop a wheel spinning the brakes will snap on and off (which could be why people keep passing you- put the ditchfinders on the front).

Do you think the ditch finders on a back of a RWD car may cause the ABS to kick in and that's what I am experiencing?

Rotten bodywork.... wrong suspension.... (potentially) dodgy LSD.... ditchfinder tyres..... :eek:

did you send a blind monkey to buy this car for you?

Surely you mean a blind unicorn?
