I decided to change the first release engine sound because it was not as good as what I expected.
The engine sound is switched to another sound set which I've already made for '59 718 RSK spyder (also a 4cyl. 1500cc boxer).
Our next development target was '59 718 RSK spyder. We've planned it before official announcement of Porsche pack release.
The mod project was aborted with the official release of 718 RS60 spyder."
