i have an s2k on jrz single adjustable, i think my rates are 450 front 550 rear. does anyone have an idea where in relationship i might be to that "magical" number of 1 g. i hear g-techs are not accurate and want to see what my car really does...streets of willow in nov will be my first track outing since the jrz's went on.

 

Don't you think a bit of that depends on tires?

 

Shocks have little to do with absolute grip level; tires do. S02s are good for about 0.9g, while RA1s allow up to about 1.3g. Some of the guys on slicks have seen up to about 1.8g. To go much above that you need real aero.

 

Like this?



I'll bet he could pull 1.9 at least
(That's on street tires too!)

 

I wonder when F1 will start requiring g-suits...

 

In addition to tires, the type of surface that you are driving on is also a major factor.

I don't know the answer to that. <<<

But I had to smile on Tuesday trying to explain to a co-worker why I was sore after two days of track time at FCT04

 

You cannot do much more than 1.2 g without and aeroeffect /downforce!

 

I think he's quoting transient numbers. If you look at a graph of g-forces for a car on a track, the steady-state grip (what you would be measuring with a true skidpad test) is rarely going to go much over 1g, even with race tires, etc (unless you're carrying speed and have aero). BUT, in transitioning, the car will see peaks of g-loading that are quite a bit higher than the stead-state levels.

I agree that shocks don't have MUCH effect on steady-state grip (that's mostly just a game of rubber), they do have an effect. I felt like JP definitely had more grip in the turns at Buttonwillow earlier this month than I did and we were on the same tires.

 

No, I was talking about steady-state. R-compounds will sustain 1.2g without aero, a little more if there's significant banking (and I have the telemetry to prove it).
