    Nice to see your doing well i bet your dads really proud of you. More work to do over winter?
    It feels good to beat other machines where money is no object, in something your trying to keep ‘standard’ ish. Although my mini racing is a totally different kettle of fish! Well done see you m.o.t time!

    Thanks Jon – certainly does feel good. I’ve got a whole load of evolutions in mind for the winter – but we don’t do our last event until late November so its going to be a short and busy one!

    Between now and then we’ve got a gearbox to rebuild, again!

    Road going LR is the next one for the MOT treatment – see you soon.

    Nice colour scheme! As a matter of interest, where did you get the GRP doors for the Disco. I have been after these for a while to loose some weight on my 5 door, but haven’t been able to find anyone who makes them.

    The GRP doors were made by Richard Hopkins of, I don’t know whether he still offers them, but it would be worth an ask. They are incredibly light compared to their steel counterparts.

    like to know what the actual saving in weight is with the GRP doors. Is the rear door also made from GRP. Also i would like to know where these can be bought

    Regards Eyck

      Hi Eyck, the GRP doors are significantly lighter than standard doors, but I’m not sure how much of a saving they are over a cut-down standard door with perspex windows. One of my projects for this year was to have a look and see. They are fairly flimsy, but very light. The rear door is also GRP and I would imagine significantly lighter than even a cut-down standard.

      Richard Hopkins of used to do them, but I don’t know whether he still does.

      Best regards

    Looks great, especially with all the mods you’ve added on. Bet that 3.9L V8 is quite thirsty!

    It’s truly very complex in this busy life to listen news on TV, so I just use internet for that purpose, and get the latest news.
