Dutton Kit Cars and their owners
Just managed a couple of hours in the workshop. Been meaning to get the corner weights measured for a while, so have had a bit of time to thing about how to do it without handing over the car to a competition prep company or shelling out a fortune for proper corner weight scales. So... The Kemp Method. You will need:
8 pieces of 30mm thick decking board, cut to 320mm long. 4 need bevelled edges.
1 Salter Max Bathroom scale, rated to 250kg, or equivalent.
Arrange as shown, the bevels used for getting the car on and off the wooden step more easily, so are placed at the rear.
Then, one corner at a time, replace the front wooden step with the scales and roll the car forward.
I took three measurements on each corner, and worked out an average:
NSF = 184.0 / 184.0 / 183.5 = 183.83kg
OSF = 167.1 / 167.1 / 167.6 = 167.43kg
NSR = 167.0 / 166.3 / 166.3 = 166.53kg
OSR = 167.4 / 166.6 / 166.2 = 166.73kg
So, this gives a total weight of 684.53kg, and a front/rear split of 351.27/333.27kg, which works out at 51.3% front to 48.7% at the rear.
Buggered if I can figure out why the left front is so heavy. Could be an un-even ness in the garage floor, or maybe the right front spring is stuffed? But, either way, I'd have expected to see the difference reflected in the diagonally opposite corner.
Anyway, that's how to get your corner weights (and puzzle yourself with the results) for twenty quid.
