Best mode for moderate to heavy rain?

[bamagrad03]

As I understand it, the wet PTM mode is for the track and actually might be bad fire heavy rain under normal conditions

So what to do when it rains? Just a normal sport/tour?

Yeah I just do normal and don't drive like a goon

When in doubt I just drive in tour mode. I've fishtailed a bit in heavy rain with water on the road on acceleration in sport PTM mode (my V setting) and when I switched back to generic tour it completely calmed down (mollifying the wife who was freaking out)....

The ice/snow mode is great for rain. It regulates the throttle and minimizes your chance at wheel spin. Highly recommend in the rain!

All these modes do is change the throttle response, power steering weight, dampers and exhaust.

Its rain, leave it in tour mode and drive like you are behind the wheel of an Impala being driven by an old lady on Sunday to church.

Its not overly challenging to drive in rain, as long as your tires aren't bald. You just drive normally.

This is what I do. Haven't had issues yet. Also haven't driven in a torrential downpour yet

These are some slides from a Spring Mountain presentation regarding PTM wet & dry:

Do you have access to all of those Spring Mountain slides?

 

[Dirkbg]

No, it was a web presentation and I snapped pics of some of the PTM modes for future reference. These are the only others I took:

I think there's another thread where the PTM stuff was discussed.

 

[5VBW Nick]

Nice, have to try to learn and remember these so I can be ready for Spring Mountain in April.

 

[Dirkbg]

These are some handwritten notes from Spring Mountain, additional details of PTM:

Bottom line for the above is there is always some level of TC. I do think it can be turned off completely, but you have to take extra steps to do it. Otherwise, it's always there regardless of what it says.

These following notes from the Zoom presentation regarding how to drive on the track. Should be fairly clear. The last line is if you need to pull over for some reason, you point where the following car should go as you pull off. They'll give you all that info, but you can think about this in advance.

Info on slides provided by @Dirkbg is correct, but for the purposes of this question...as @BlackDiamondCT5VBW said above use regular drive mode Snow/Ice as opposed to PTM Wet. They are not the same.

 

[Yalferd]

Forget PTM, drop down to Drive Mode for Snow/Ice. We had torrential rain during my Spring Mountain experience and it worked great to keep the car going straight

 

[Champale]

The main thing is to be smooth with the gas and steering. From personal experience, you can catch the stability/traction controls napping even in Snow/Ice mode in a 5BW if you hammer the gas in heavy rain.

This is a great summary of the various PTM modes:

I never considered changing drive modes for a snow storm let alone a rain storm. I just drive with awareness.

We had our 1 out of 5 days of rain here in socal last week with heavy pours and I can say there are (2) ways to mitigate slip.

1) Just being gentle and smooth with throttle inputs. My car has the Michelin ps4s and surprisingly does not hydroplane very easily. It does give you time and feel before you know your in deep sh*t
2) If you put it in snow/ice more it does #(1) for you and puts your yaw and traction sensors into a more sensitive mode. The second month I had this vehicle we did get heavy rain and I did put it in this mode because I was just not used to the way the car delivers so much torque down low. But after DDing the car for so long its pretty easy for me to control it, even with rain boots on and with a clutch to kick .

If you are slipping right when your pulling out of your driveway you should either put your car in the snow/ice mode right away or the road conditions just arent safe enough (maybe too cold for the summer tires?) to be driving the ct.

lol. I look forward to those drives usually. I am also on a snow tire for winter at least.
