I'll give you the same answer to that question that Al Oppenheiser gave me when I asked him for an explanation as to why the rear brake rotors on the 5th Gen were actually larger than the car's front brake rotors...
"... because that's what I decided it should be."

Good enough for me.

i can deal with that.

Does the Camaro have unequal length drive shafts to reduce wheel hop???

you mean half shafts? no. they are the same length. different diameter tho.

(^) What Spike said. The unequal diameter half-shafts he mentioned plus some other tinkering is supposed eliminate wheel-hop on the Camaro.

.... just remembered, I have already gone over this before...

CORVETTE ZR1:

GM uses unequal-diameter half-shafts in the rear - 40mm on the left, and only 33mm on the right. Although the manufacturer has not explicitly stated why it does this, it's very likely that the left shaft experiences larger torque loads during hard acceleration. Making both shafts the same diameter would result in increased weight, and the Corvette team fights for every pound.

GM won't explain, but autoblog thinks, and it sounds reasonable, that it is done for weight savings alone.

The physics of equal LENGTH half-shafts on a Front wheel drive car, to prevent or diminish torque steer, should not be confused with issues and remedies for axle hop on a SRA or IRS vehicle.

G8 is, for lack of a better term, "Zeta 1" -- and the Camaro is "Zeta 2" -- many more improvements.

I'll quote Al Oppenheiser when asked about Axle Hop: "....WHAT axle hop???..."

Now -- that said, I'm CERTAIN that there will be a few that TRY to get axle hop -

.........let's face it - no matter how 'robust' we design it, there will always be those who try to 'blow it up".........

I think the term used to describe the half shafts is Asymmetrical.

I wouldn't trust autoblog to think.

GM did it for harmonic reasons. They did a lot of testing for the zr1 and found that most of the issues of wheel hop are harmonic in nature. This is why spring rates don't fix it and why over-damping can help (but at a cost). Tires don't just slip. They still try to grab. This causes the rear suspension to begin to bounce and then you get hop. It's well documented in most IRS cars. The only way to change the natural frequency of something is to either change mass or stiffness. This does both. The different diameter half-shafts then cause each side to oscillate at a different frequency therefore reducing total suspension hop.

autoblog got it dead WRONG. they say that the left axle shaft is the 40mm one and the right is 33. thats backwards. and that they made the 33mm one smaller for weight. no. they made the right 40mm one larger to eliminate resonance in the shaft.



read the post in the link I put up. it explains it all very nicely

good choice on not trusting their knowledge prowess


moreso than just oscillating at a different frequency, the extra weight/thickness of the larger shaft allows for reduced resonance to begin with

^^^I believe the resonance issue has already been covered too, but good explanation spd98. Thanks!

NICE! I wouldn't have thought of that.
