stock ADVAN's..
 

am i just a crappy driver, or do the stock ADVAN's fare not so well in the cold. i know its been discussed...but man this week has been super cold. temperatures in the low to mid 30's when im leaving for work. the freeway onramp by my house is on an incline and the light is at the top of the incline. i cannot for the life of me launch without getting wheel hop!

the other morning i launched at around 3k, give it probably 50% throttle...VDC light just comes on and im hardly moving until i let go of the gas.

this morning i tried around 2500....VDC light comes on, same 50% throttle, some wheel hop, but im moving a hell of a lot faster than i was yesterday.

i mean..i could just normally launch, and drive as if i was on a normal road, but the merge lane is reallly short, and some of the cars are flying. if i dont gather speed quickly i feel like a douche when the car im merging with has to slam on their brakes for a white sports car thats driving slow :eekdance:

Summer tires turn into hockey pucks in the cold. They are not recommended to be used at temps below 40 degrees as they are very dangerous until you are able to get some temperature in them (takes about 15 minutes or more of regular driving to get them to start gripping).

Just take it very easy until you are able to get them warmed up. They have no grip when they are cold... none!

This^^

heh maybe i should start taking laps around my block before i head for the onramp :icon18:

It would take a lot of laps. You probably should just accelerate slowly on the ramp. When the tires are really cold they are very unpredictable so it's much harder to save the car when you start to lose it.

The Advans are fine after they warm up a bit. They act more like real race tires than some streets

hahaha yeah cold advans doo suck

I broke the rear loose last night 2nd gear and 28F. Just eased into the throttle exiting a curve

Anyone else having a problem with the back end coming lose on a 1st to 2nd **** as well as 2nd to 3rd shift. Was having a little fun the other day with an M5 (not racing just following behind him at a spirited pace) the other day and it was 53 out. Tires were somewhat warm as I had just driven for 25min parked for about 30min and had been driving for about 10min. I know not to launch the car as as I only get wheel hop but when I shifted into 2nd the back end popped sideways a little until the VDC kicked in. Did it again going from 2nd to 3rd but not as much. I was at WOT but shifting at about 6krpm. Car is stock other than a FI exhaust.

I just have very little confidence in this car unless it's summer. Roads here aren't the best and going over bumps at speed causes the VDC light to kick on. I'm worried one of these days I'll spin out just from the road not being smooth. Our old C6 corvette was similar but quite a bit more stable (with stock runflats)

It's not really a "problem." It's a relatively high-horsepower car... traction will always be an issue. It's just even more of an issue when it's cold outside!

You just have to adapt to the conditions and drive through it. If you're worried about trashing the car due to some rough roads then you should just slow down.

I'm not talking only about spirited driving. I'm talking about when I'm driving at a regular speed on the freeway and there happens to be a bump in the road from uneven roads which causes the back end to come out a little and VDC to kick in. Not really complaining as I love the car but out of all the cars I've driven (all of which have been RWD sports cars aside from my WRX) this car seems more unsettled going over bumps at speed. Maybe when I switch tires later on down the line it will be better.

How is the Mustang compared to your old Z with traction? I know my girlfriends Camaro seems a lot more planted and the electronic nannys are much more forgiving as well as smoother with input. With the Z it seems like the VDC is either on or off where as the Camaro it seems that it slowly comes on and off so as not to surprise you. Also traction wise the car seems much better despite having more hp, torque, skinnier tires, and less traction rated tires. I'm sure the added weight of the car helps some though

was happening to me quite a bit today. i would hit a bump, lose traction. just have to get used to its quirks i guess. does make for alot of fun though..just have to be careful

The Mustang has a better VDC system. Traction control and stability control are separated unlike the Z's VDC wher ethey are combined. You can turn SC off but leave TC on. You can turn TC off but leave SC on. You can also engage Sport Mode which allows for something like 10-15* of yaw before SC kicks in and it will actually will modulate the throttle a little bit sort of like launch control if you really start to spin the tires too much. But it doesn't cut power off immediately like the Z does... it will let you spin them if you get too aggressive!

As far as traction goes... with the summer tires I have pretty good traction but the tires are only 255 all the way around and with 400+ hp I think you need more tire. I can spin all the way through 1st, 2nd, and most of 3rd if I am just ******* around and don't make any effort to really control the car. I'll be upgrading to 275 Nitto NT05s or similar all the way around in the future and that should really help with traction.

Right now I'm on a 245 width Dunlop Wintersport M3 winter tire all the way around and the car will easily overpower those tires, so I have to be really careful.

I agree with you that the VDC system on the Mustang is smoother and overall less intrusive than the Z's. I find that I never turn it off unless I go to the drag strip. When I want to hit up the back roads I just switch on sport mode. It tightens up the steering which is very nice. Smooth when I'm just cruising on the street... aggressive when I really want to have some fun.
