Thank you for the friendly welcome.
The Seven was an early pre-litigation Westfield - and so very similar to a Mark III.
It originally had an A-Series but evolved into an 1800 twink carrying twin Weber 45 side draughts, lit with Dunnell ignition.
I finished it with an Escort Mexico live axle and diff, Princess 4-pot calipers and Spax dampers.
With 300bhp per tonne, it was fun.
The Rapier underwent full restoration and sported a Holbay top-end on 40DCOEs, with brazed manifolds, and was regularly on the rollers after head work and camshaft experimentation. I sold it to a chap who completed the Monte Carlo Rally in it.
The Spitfire was a significantly modified Mark Three, on a 68 plate. It ran a 1296 on twin SUs with a Jigsaw cam. It had a camber compensator and was in the weeds on semi-slicks. With a roll-cage, extinguisher and all that jazz, the photo shows it in the paddock at Castle Combe.
Prior to the MX5, I ran a BGT as my daily vehicle. It was a 71 in Tundra Green. Apart from some minor improvements to the brakes, it was stock.
Guess you will not be leaving your Z4 standard. Life will be fun.
