AND, its gotta go if you put an R-DRacing Camber Brace between the top A frames. The Camber Brace is one of the better things you can do to this sportscar.

Frisbe
I'm new and just found out about the frisbe on my 1990 L98. Can someone give me the skinny on its removal. Do I need to remove the pully and belt, is it safe, and will I feel it on the throttle?

Removal of pully and belt aren't needed. Get four small lock washers to put on the bolts to replace the thickness of the frisbee. On earlier models this wasn't needed but on my 90 the bolts bottomed out before the pully was tight. Do this and you'll be ok.

You won't notice any difference in the throttle. You might see a couple hp on a dyno. It si there to tampen the shock when the A/C compressor kicks in.
I had to reinstall mine as the compressor made an awful noise when removed. Mine is an 88 w/ the A/C converted to 134A.

Make sure you have a long breaker bar with you. You'll need it there to hold the frisbee in place, while you try to get the bolts out. If you're using an impact wrench, you won't have that issue.
I had an issue when I took mine off that it was making a horrible sound. All I had to do was tighten it even more (which, too tight can cause damage, so be careful..) and it was fine.
Best of luck!

Not to restart an old thread, but ...
Not to restart an old thread, but ...from the information here ( I have a 91 and would like to take off the Frisbee as well), I would not have to take off the pulley or the belt ??? So, just the four bolts, add some washers and nothing else ??? Sorry, to take the threrad, but it is on the same topic and I am somewhat tentative with the engine aspects of the Vette (regarding whacking it with a hammer 
)
Thanks

If you look at it you'll see that the frisbee is actually mounted to the waterpump *through* the belt pully. No belt/pully removal is needed. Just remove the four bolts. Remove the frisbee. Place four lock washers on the four bolts (one each) to replace the thickness of the frisbee mounts and reinstall bolts. This is to ensure that the bolts dont bottom out before the pully is secure. It's easy as pie.

Dave, i was out trying this the other night, i couldnt get the firsbee to stay in place while trying to break the bolts loose, it just wanted to turn. How does one hold it in place so it doesnt turn? I have no air tools, just regular tools.

I didn't have to use any lock washers when I removed the frisbee from my "89" and "91" Vette's.
I just removed the four bolts, removed the frisbee and reinstalled the four bolts. The bolts had plenty of clearance and the pulley rotated fine.

I used the tension of the serp on the pulley along with a large screw driver across the front of the pulley to hold the pulley while I broke the bolts loose.
Then I removed tension on the serp (don't what the pulley to go flying when I remove the bolts...
) and removed the nuts & frisbee.
My '88 had studs holding the pulley & frisbee, which I replaced with bolts & lock washers.
Time slips show it releases about 10chp, i.e. 1mph gain in trap speed.
