HHR SS Lateral G's

How is this even possible but I hit .92G's on my SS the other day. I was coming off a highway to a circular exit ramp a little quick and although the SS did a little sliding around the turn it took it pretty good with just a light touching on the gas to keep it even around the turn.

I looked over at the Proformance Dispaly and it showed I just hit .92 Gs. Im on stock tires and I really thought the max Gs was around .86 Gs.

Quite Impressed!

Maybe a little banking on the exit ramp gave you a little extra bite.
I would guess that you pretty much "maxed" it.
Be careful though. Going off road could wind up being expensive.

There is an on-ramp to the 5 fwy in Everett going north, flat and sharp, saw the flat, did not see the sharp, stock tires .97 on the RPD. I thought for sure I was going into the outside wall but she held with minor tire slip, scared the S__t out of me for a minute, what a rush.

I have a nice decreasing radius highway loop (these are especially dangerous for motorcycle noobs) on the way to my work. There has been a few time where some jacka$$ riding my bumper into the turn has fallen off into the weeds. I wish I had the G meter. I'm on Firehawks. Don't know how they compare to stock, but it sure is tough to get them to slide at all.

I got a .85 (with no squeal) the other day on a rutted offramp. With 100 degree air temps and tire temps at 140ish the NT-05s were definitely up to temp and sticky.

The GM number was set on a specific Skid Pad and the car is tested at a specific radius. Think of GM's skid pad as the ruler and has a set scale.

Sorry but off ramps are not built to the same spec and your results will vary. On the right ramp you may even see 1G but these numbers mean little unless you do it to the same spec that GM used.

Note when GM did the SS they left some G on the table because they also wanted a fully well balanced tune for real world roads. GM in the past has been guilty of too much spring or bar and while if the road was smoot it was like a race car. Now if the road was bumpy or uneven the car would bounce or wander all over in some cases.

GM PD used the kind of settings many Euro MFG use and the results are one of the best handling FWD GM has ever done.

Many times more is not always better.

G-loads are measured on a flat ,300ft radius skid pad. Anywhere else is just stroking it, for the sake of talk. Of course, it does matter out of the track. "Moon"
