Drew has been a long time customer of Heasman Steering who have been helping him build his R34 GTR track car for the last 3 years. Constantly chopping and changing things, trying to get the absolute most out of his car; Heasman’s has stripped down the whole interior, cut every bit of unnecessary metal out of the cabin and even removed the dash and replaced it with a custom light weight aluminium dash (which they built).
This time around Drew wanted his wing higher up and further back in an attempt to get it into some cleaner air, but at the same time it had to abide by rules and fit within the regulations of his class. Heasman’s drew up a design using CAD, and got it laser cut. They then pocketed out the inside of the mounts to make them lighter.
In-house CAD design: Heasman Steering used the existing wing support to tool measurements off the car, and from there they designed a new wing mount that maximises the wing position within the rules.
Main body was laser cut.
They pocketed out the centres on the mill to reduce weight, and give the wing mounts maximum strength.
Because the car utilises a dry sump set-up they couldn’t use the boot floor to support the wing so Drew had to bin his carbon boot and buy a factory metal boot, which was then stripped and reinforced with aluminium. The result was amazingly lighter than carbon boot it replaced.
Test fitting.
The wing itself is made by American company Aeromotions which are developed at MIT and refined in a $42m wind tunnel (!).
