He located a limited slip differential for the Jaguar, and fitted it during reconditioning of the cars rear axle and rear suspension subframe unit. The car was then used "as is", with no initial attempts at lightening.

Despite the Jaguar XJ40's relative bulk and weight, grip proved to be one of the limiting factors, and Dad procured a set of used 9 inch wide 18 inch diamater Jaguar XK8 alloy wheels with tyres. These needed slight modifications to the bodywork to clear the rear wheelarch lip, and the front centre cap badges won't fit with the wheels on the car (these need to be removed anyway for track use, to prevent them flying off in a hazardous manner).
He also fitted a set of SuperFlex front polyeurothane suspension bushes to replace the standard rubber items - this has improved the Jaguar's turn-in.
