Keeping the rear differential temperature of the R35 GTR in check and
at acceptable levels requires external cooling, and we have achieved
this with a fresh new Willall Racing cooling product.We call our R35
GTR Rear Differential cooler WR35DC and it's fully engineered from top
to bottom as all our products are to work seamlessly on a track
orientated or hard driven R35 GTR without cutting or drilling anything.
Here are the parts that come in the complete kit.
As you can see this is a fully comprehensive kit as per other Willall
Racing products. Nothing needs to be cut, shut, moved, or modified to
fit these parts, with the result being to cool the high operating
temperatures of the rear differential that can run to an excess of 270F
in the right hard driven conditions (and closer to a constant 210F when
WR35DC cooled). A CNC machined mounting bracket, 13 row cooler, high
pressure and temperature crimped lines and every other nut, bolt,
fitting, and mounting part you need.
Some neat touches that show the full level of the engineering we have put into this product are -
1) A new air deflector system from under the rear differential that
bolts in place of the factory part and provides adequate clearance.
2) A 'Jacking Point' adatper that bolts to the undertray and means you
can still jack the car off the factory point without damaging anything
or pushing against any part of the WR35DC Rear Differential Cooler
system when changing tires at the track.
