Bouncing speedometer needle/Capliers
Is there a fix for a bouncing speedo needle, it is bouncing 20-40 km/h over or under where it should be.
Also i took my car to a deserted road to test it before taking it to the track and tried to do a little burn out before and i can't even do a proper one, my car kept moving forward because my calipers are leaking so much, so there is not enough presure to keep the car still i guess. What kind of calipers should i get to replace my 30 year old ones? Oring SS calipers?

A bouncing speedo is typically related to a binding cable, so.. replace the cables.
As for the calipers, I simply put stock replacements on mine. Cheap enough, and they perform pretty well. Later when I do more to the suspension, I'll definately get a better system put on, but that's a lot of time and money later.

Justin, the bouncing speedo is most likely the cruise control transducer.
As for the brakes, go with the O-rings from Vette Brakes. Very nice and not too expensive. IMHO, I wouldn't waste my time with any other. The O-rings will go a long way towards stopping any kind of air pumping on the rear calipers, from run out issues with your rotors.
Also, you could just rebuild your calipers. It's not very hard, and a lot less expensive. Pull one of your calipers and check out the condition. Two bolts will separate the caliper body. Pull a piston and look at the bores. If they are in nice shape, buy an O-ring kit from VBP and have at it. You could do the whole job in an afternoon and save some money while you're at it (especially the B.S. core charge...).

I've heard rebuilding 4 piston calipers was difficult?
SHould i get the o-ring rebuild kit or the o-ring caliper conversion kit? Since mine probably have the lip seal would i not have to get the o-ring caliper conversion kit?

don't believe it! I did it this past year and found it easier than suspected. Of course, you've got to have some mechanical aptitude but if you do your own work...you'll find a great sense of satisfaction in its completion.

I got rid of my bounce by buying a speddo cable "greaser". I think I got it at Mid-America. It screws into the cable and it allows you to pump grease into the cable. I have lent it to others in my club and it fixed theire too.
