Re: virus projects?
from the action center...I spoke with Jim Ingle recently who was a Corvette Powertrain Engineer and did a lot of the develoment testing on the ZR-1s. Most of the GM performance figures you see for the various years on the ZR-1 were established by him. I asked him about the use of steel half shafts and why the switch to aluminum. This is what he had to say:
"We had difficulties staying in the EPA weight class we needed to be in to avoid paying gas guzzler tax. Of course, this was prompted by crash and bumper standards that resulted in weight increases. The aluminum axles were part of the weight reductions used." -- Jim Ingle The half-shaft was changed early in the 1990 model year starting with VIN # 800621.
