There's no two ways about it: a Triumph Spitfire is a technical beast. For some of us, that's the main attraction of it. Here are some stories and how-to's about technical subjects.

Spark plugs page

Reading spark plugs is a much underrated means of informing yourself about your car's engine's health. Much can be told from the colour and structure of the deposits or the damage you'll find when you unscrew them and look at their nose. Judiging from the stats, this page has been popular with many owners of petrol engines. Not just Triumph Spitfire or even car engines, but also lawn mowers, snowmobiles, chainsaws, you name it.

 Storing your hard top

Triumph Spitfire hardtops, especially of the later, angular steel version that was found on MkIV's and 1500's, are heavy and unwieldy things. These days they're hardly used by most Spitfire owners, it's just a nice accessory to have. But where to put it if you have one? I say hang 'em high - and here's how. This method might also be useful for owners of Triumph TR6 and Stag hardtops.

 Fixing a rear transverse leaf spring

The transverse rear leaf spring on Triumph Spitfires can be a source of endless head scratching, pub discussions and general misunderstanding. The rear of a well-travelled Spitfire may be sagging, or the front may seem to be pointing upwards. Most of this can be traced back to the rear transverse leaf spring. A saggy bottom is nothing to worry about and in most cases it's not even a reason to replace the rear spring. There's another way to tackle this. It's cheaper and just as good as replacing the spring pack with a new or retempered one - this may even be a better way.
