Rear radiators have become commonplace in drift competition vehicles. Depending on your preference, the balance may be optimized by mounting it on the differential, but if it is left as it is, it will succumb to the turbulence in the trunk and the cooling efficiency will deteriorate. Therefore, by installing a shroud and discharging the air to the bottom of the trunk, the fan’s original performance can be demonstrated and cooling efficiency can be improved. In addition, since the radiator itself does not need to be laid down, it can be avoided from the crushable zone and damage to the radiator due to contact etc. can be prevented. Size W=760mm H=440mm Depth 240mm. There are ears (approximately 20mm) for fixing the radiator in each direction, making it easy to fix it to the radiator. Electric fan maximum dimension 370φ. Most radiators currently on the market have dimensions that can cover most of them. The surface is an epoxy layer similar to dry carbon.
