I have read that it can quite things down a bit.
My son picked up a 1978 280Z with about 115k miles. Hardly driven at all the past 20 years....A little rust but manageable. He and I are working on it together.
Did a search and did not see this product discussed. Planning to put Redline MT 90 in the transmission, but looking for recommendations...and one of the Redline Shockproofs in the differential, but would consider other options. Things work ok but am trying to quiet things down a bit (gear noise)....Noise travels I know and replacing rear bushings (Mustache is done) and bearings are next.
And I have the FSM by the way...
Thanks in advance.
