New shoes
Pics will be posted over a couple of days since I'm mounting and balancing them myself after work.....
Wheels...... 2004 thinspokes that previous owner said he never ran.....and the wheel condition actually backs up his statement.
Tires GY GSD3 275 40 R18
One assemble took 1/2 ounce to balance on the hunter machine.....the other only 1/4 ounce......
I couldn't believe it so I removed wheels from balancer (after placing the single wieght where the laser indicated.....new technology ROCKS) mounted them in the balancer again and this time 0000 and 0000
so the 1/4 and 1/2 was it.
The rears.....
I'm reusing the front tires and I'll probably have the time to unmount/remount the fronts by Thursday...
I've always liked the looks of the thinspokes and the 275 40 r18 is just enough taller than my current tires that I should bust 150 in D/3rd vice 146......and 18s were cheaper than my current 17s so with the low price of C5 take offs its a win win.
What are you guys doing for your C4s????

I bought these 03 Anniversary rims from a Forum member. 17" front, 18" rear. I did not get the centers with them so I bought a set from Vette2Vette but still have to paint them to match the "champagne" color.
I like the look of the thin spokes.

Had time to unmount the front tires IOT mount them on the new wheels. 
Once again less than an ounce on one, however, the other took 1 1/4 ounces.
So I installed the fronts and went for a ride IOT see if there was going to be any shimmy, shake, vibration etc....
Good new everything was golden
So I lifted the rear using a method not shown in the FSM...
Installed one side then the other
While the car was on the jack I tightened the spring bolt two turns on each side IOT raise the rear a RCH since the 275 40 R18s are a little taller than the 285 40 r17.
Then I adjusted the speedometer for the new tire size
And went for another drive IOT check for shimmy, shake, vibration etc... and there was none
Problem is suspension hasn't settled yet...
