Yes, the door speakers are now out of the TR7 and in my loft!
Also removed are the CDs I had in the car as they are clearly surplus to requirements. As a matter of interest I weighed the CDs and they were 2kgs alone.
Removing the radio-cassette, electric aerial, door speakers and the CDs (!) I have found a weight saving of 5kgs which can't be bad - it all counts.
What I must remember when this competiton lark gets semi serious is not to run with a full fuel tank - 12 gallons of petrol must weigh alot and have a performance penalty.
