Willall Racing in Australia have developed a number of products for the GT-R, aimed at lowering the high oil temperatures that owners have seen when using the GT-R on track. Oil analysis of the OEM transmission oil shows a lot of wear of the gears in the transmission. The Willall Racing oil stops this wear and helps your transmission stay healthy longer. For those that run an aftermarket exhaust, Willall has developed a front mounted transmission cooler as a no cost option. Here are a few pics of the Willall Racing products:
