The engine oil sump has been lowered by one inch by using a bespoke alloy spacer.

The engine oil pick-up pipe and filter rose has been lowered to suit.

The high capacity bespoke radiator is of aluminium construction.

There are two cooling fan switches fitted to the radiator, one at the top and one at the bottom giving an option in operation.

A brake bias knob with lock, marked F & R has been added to the right hand side of the dash, near the ignition keyhole.

The first time I raced the TR I kept the original seat, realising it was not Ideal, I chose to remove the very comfortable seat back and squab and replaced it with a "racing" sit in a bag of foam type. This gave me much more room and brought my seating position much lower in the cockpit and was also a snug fit.
