Suspension Roll and pitch angles???
Anyone know what the approximate pitch and body roll angles are per G on a 2000 convertible FE1 Base suspension/sway bars etc.?
I just got a new Beltronics Vector G meter 'toy' and I want to make sure that I have it set up correctly.
The unit defaults are 2 degrees per G in pitch and 3 of body roll per G. Seems a bit high for a Corvette. Any of you autocrossers on top of this one?
Thanks in advance.

The base C5 FE1 suspension is actually quite soft compared to the Z51 or Z06 versions.
Approximate calculated roll gradient:
FE1 (Base C5) 2.4 deg/G
Z51 1.7 deg/G
Z06 1.4 deg/G
Don't have pitch data handy.

Those numbers may be low. If the base suppension corvette is doing a 1G corner, it would slide. Base run crap tires would not hold very well.
Dont know the exact numbers but from personal experience of driving many many corvettes with different suppensions on the track, your looking at 6-8* on Base, 3-4* on ZO6 and 0-1* with T1 suppenssions.
However these are not subjective numbers and the DRIVERS skill will have more to do the pitch and roll in corners.
If your taking a 1G corner, your ears will POP and most ppl can not physically take a 1G corner, let alone have the skill to drive and have the tires to hold a 1 G corner.
In a High speed braking zone on a road racing track a 1+G braking feels like your ears POP and your stomach is coming out your nose.
that is if you have the brakes and tires to do they powerfull of stop.

My ears don't pop at even 1.4Gs cornering or braking....I've never even heard of that. We have little old ladies that pull over 1G at our events...
Hell F1 guys have to deal with 4Gs

Montreal F1 Gp 2004: 5.7 inline G (decelerating G's) in the braking zone for the hairpin during qualifying, # stay at the pike for a couple of tenth.
According to the physio in charge of some drivers there, the eyes have a tendency to pop out of their places.
Fun enough no ....

Thanks ATI
Thanks ATI for the info on the roll gradient. I knew the FE1 is soft and that number is about where the Beltronics has its defaults set for the roll so I will go with their defaults for the pitch as well.
Don't know where all the rest of the guys went off to on their tangent about ears popping.
Thanks again for zeroing in on the issue.
