after 4 years my rear Pirelli tyres still have some profile but the
rubber becomes pretty hard so traction gets worse even on hot summer days.
The V8 is spinning the rear tyres with such an ease that I decided
to grant a "smokey burnout" to myself .
Switched off traction control completely by pressing the button for
more than 3 seconds , got warning in the instrument cluster , floored
the pedal , rear tyres began to spin , car picks up some speed which
I tried to prevent by applying the break pedal with my left foot .
Up to a certain pressure this worked but the car still became faster.
Increasing the pedal pressure suddenly software kicks in followed by
a sudden close of the throttle. Same behaviour you see trying to drift
with traction control on.
Tried whole procedure several times but still the same result .
What I'm doing wrong ? Does my car stick in "trac dsc mode" ?
What´s the behaviour of your cars concerning "brake against throttle" ?
Any advice appreciated .

Normally you have to hold the DSC button down for at least 12 seconds before "DSC off" flashes up.

 

Someone is Michelin shopping soon I take it?

 

I have to say i've noticed the same thing. These stock tires really do not age well... they lose a lot of grip.

 

The RWD car is unmanageable with stock tires. You can't get on a throttle in any gear. I am not sure if it is Pirelli that are bad tires or they not right for the car, but it is like driving with a parking brake engaged...

 

I saw the name of this thread and had a completely different thought. A week in the Caribbean.

 

I often drive with the DCS completely off and I've never had any electronic interference to tire spin.....that said I have not tried powerbraking/doing a brake stand with the car. I turn the DCS off, engage paddles, put her in 1st and mash the throttle and spin through 1st and usually second before letting off.

That's the undocumented Hooligan Mode.

 

Yep. I often drive with the "nannies" off. Some people here think you should be locked in a padded cell for that, but it all depends on what you're used to - I'm an old musclecar guy and have spent many hours behind the wheel of massively overpowered cars where the most electronic interference is an AM radio! ;-)

Cheers,

I promised myself I wouldn't drive with DSC off until eventually replacing with PS4s.

Everything is relative though. A '71 Pantera is unmanageable.

 

Yep; try a 1968 GTO with a 500hp 427, posi, 4.56 gears, drum brakes and 245/60/14 tires.....compared to that the F type is a pussycat with it's modern chassis, huge tires and brakes, etc. etc. I wouldn't go so far as to call the F type boring, but it's far from being the handful that many of my older cars were.....even with the nannies all the way off! ;-)

DPelletier and Burt Gummer,
It's funny you guys should mention the Pantera and the '68 Goat, I happen to have both of them! The Pantera is coming back to me this week after a 2 year restoration that included an engine transplant (300 hp to about 550 hp in a 2900 lb car), and the GTO goes in for full restoration when I pick up the Pantera. The Pantera barely had any traction at 300hp, can't wait to throw out that clutch with 550!

 

She's a beauty!!!

 

Drum brakes: would these have similar braking performance to my father's mid-60s Falcon? If you attempted to stop after pulling off the Interstate using just the brakes, the pedal would hit the floor while you were still doing 40+...

 

After my modded 600hp Ford Lighting pickup w/ no nannies, the F-Type even with the stock tires is a piece of cake.

Driven many death traps in my day . I don't race on the street so the drama of the exhaust and the RWD is just what the doctor ordered.

 

Nice on both counts! :-)

Dave

 

Actually had that GTO up over 150mph with those drum brakes (with 2.73's before the swap to the 4.56's)....verified by the police (long story...) It took a looooooong time to slow down! LOL

cheers,
Dave

 

DPelletier,
The '68 Goat with the Endura front bumper and the hidden headlights with the "Coke bottle" rear quarter, is most definitely my favortie car design of all time. Besides keeping me awake all through high school (as I was always drawing crude renderings of it), even when I sit in it now, without driving it, when you look out over that massive hood and see the hood mounted tachometer, the bulging hood scoops, all tapering down to that bumper (which forever changed the way cars were built, no more chrome), it's more exciting standing still than most new cars at a 150mph, so much visual stimulation.

 

Wow, how awesome, good for you!! Pantera was my dream car from when I was 11 till...
now
Is that Z stock or does it have a 350 in it??

 

Yep; I consider the '68 GTO to be the pinnacle of GTO design. I don't have a pic on the computer but ours had the hidden headlights and hood tach as well; beautiful car. It looked completely stock and originally had the base 350hp 400 in it but someone swapped a solid lifter 450hp 427 out of a '66 'vette into it along with headers and a couple other goodies.....not what I would have done but it was a beast; nothing in town could touch it back in the '80's
