I have read many posts that say it's ok but I am a bit skeptable (SP) about it. Please help!! Why would GM put it on if it really has no purpose at all? Is it there for some kind of balancer or something? Forgive me if this is a really dumb question but I am not a mechanic, just a body-man. :confused:

HI....thnbluline50.....don't think anything of it....i too am about as picky with my vette as they come....basically....all that frisbee does or once did was GM felt it would help dampen an intitial vibration that would occur when turning the ac on....later it was removed....GM took a closer look at this and realized....the L-98 really did not benefit at all from it...like they once assumed....

there is a techpost located in the corvetteforum tech tips section that explains that this once 10hp free mod that was only talked about from guy to guy...was actually asked to Gordon Kilbrew of corvette....i had the opportunity of meeting Gordon....and I will state here as well as Iam assure others will....if Gordon says we don't need that disc....everybody calls the frisbee.....then we don't....Gordon designed and built the C4....I do believe him over anybody should know if we are causing harm to our vehicles....while at Bowling Green 2 years ago...he also answered a lot of common questions about our cars and knew the answers without even thinking.....gave us all some nice little pointers and tips...

bottom line.....take it out ....you will never know it is gone....your engine may rev a tad bit quicker and higher on the long runs....just be sure to take your time and get the 4 bolts out.....put a coat of thread lock on em...and reinstall them (may require a washer) ...

enjoy

The C-4 Guru Gordon Killebrew says it is OK to lose it. It was an attempt to reduce vibrations as the A/C compressor cycled. The factory later took them off anyway.
Some people say it is worth 10HP. I think that is overly optimistic, but reducing rotating mass can't hurt.

EDIT: I see some one posted while I was typing. It was the thought that counts.
