Do you trust it?

I've had a few cold weather situations that have made it hard to trust the traction of my car. I took the car on some twisters this week and wasn't able to push it as I just didn't trust the traction. How do I get over this it is frustrating.

I was sliding around in some twisting at 64 degrees Fahrenheit

Yeah. Car sticks like glue when it's over 75 degrees

some heat in the tires makes a huge difference in confidence. These tires suck when cold as many have labeled them "hockey pucks"

Find a big open area(we have a minor league ballpark parking lot) and run it in a figure 8 until you lose it. You will find that your warm weather traction is well beyond the point of sphincter pucker.

Surprised the OP is having problems at 64*. I've heard from others I know with the Z that those F1's are like gumballs in good weather temps.

Search for an autocross in your area, you will be able to push the car as hard as you want without the risk of hitting anything but cones.

At an autocross the track layout usually will not allow you to reach speeds more than 60 mph as compared to a road course with very high speeds.

If you spin out you will not be the only one. I have a couple of youtube videos that my son posted of me racing an autocross.

Search Youtube for "Lonny Zl1 autocross Texas".

This will help you gain some confidence in how hard you can push the traction and what you can recover from.

The GY's do not like cold streets. I had the tires properly warmed and then went to my personal closed course. The back end tried to come around twice at around 10mph slower than my norm. Took it home and put it in the garage......live to fight another day. Michelin Super Sports should take care of that I would think.

I came out the parking lot left hand turn in 75 degree weather and barely got on it and the back end whipped around and that was with TC on but not in any PTM mode. These tires aren't the best by any means

My tires slip under very little throttle between 50-60 degrees. It gives me an uneasy feeling driving aggressive. Looks like I need to try new tires?

The GY F2's suck when cold.....that's what allowing you to be whipped around. I'll confirm once the Michelin Pilot Supersports are mounted. 285/35 and 315/35 outta do the trick.

My stock G8 GT gave a Zl1 a run for its money in 32 degree weather he simply could not find traction.

Happens. I had a Saturn Sky right next to me in my 300C SRT8 with 643 rwhp that ran 10.70's. Couldn't get it to hook.

Traction for me has definitely been dependent on temperature. The hotter the better. And forget wet!

I think most who are complaining about traction with street tires with a 580 hp engine just don't know how to drive a 580 hp car on street tires.
No 11 inch wide street compound tire will hook a 4100 pound car on the street with 580 hp. At the strip, a drag slick will help get you a good sixty foot time which translates into quick ET. A drag radial will produce a slower sixty foot time but better than the stock tires. MPH will be similar with good or poor traction at the starting line and will dictate your actual horsepower with a good MPH calculator that you can find online.

hahaha sphincter pucker...... That is a good way to "Safely" test you and your cars ability. I will be doing the same before Camaro Fest. Also take traction control off get to know the car that way. Took me 2 years before I started to do that with my last Camaro, I have not done it yet with my Z.

Slick for track yea, but he's wondering about trusting it in turns! And generally hook if up to I guess I know what your explaining!


You want best traction in turns and launch combo super sports seem to be the way to go, friend of mine has them on a cts-v w/635rwhp and they stick nicely

My zl1 Mikey Thompson et streets 305,35,20 will spin a bit in first but still pulls like a train and chirps trough second and feels like a plane at take off on the street, cornering I don't dare to push it to hard but still take them quick enough to have fun!

Ill know how well it hooks when I hit the track June 21st I suppose lol

Not from a dead start no. But I can confirm that these tires suck below 70 degrees. I put a tvs2300 on my SS car in the fall (P-Zeros), tested it for 2 days before winter (Around 60 degrees). I could roll on it easy in 3rd and blow the tires off at 50mph.
Now that it is in the 80's I can hammer it in 2nd and hook. Still have to roll on it in 1st.

Also, my 9 second Vega on full slicks will not hook at all on bare ashphalt. Greasy as hell. In order to hook they need a properly prepped track surface with VHT.

Not interested in dead hooking on the street, as it ain't gonna happen. I drove a 600+ rwhp car for 3 years and I'm use to feathering a throttle...well everywhere. It's about the tires being able to hold on in a corner with no throttle input. With the GY's its so predicated on the outside temp. I've never driven a street tire so finicky about temp. A track tire yes, continental sport cups, but not a street tire. Making the switch to Michelins should be the fix I need.
