Gearsets are a fairly thorough catalogue of available parts for the Hewland mark 7 and 8 transmissions. It probably has been fine tuned to more power than it had in 1967, generating over 100 horsepower, but to be fair, safety regulation changes have made the car heavier. The engine is a healthy 1.6L Ford "Kent" stock block and pushrod 8 valve head, as specified in the series rules. The brake bias and antirollbars default to a fairly safe setup even so on cold tires the car is happy to wander around the road. The default spring settings match period setups for the car, which are quite soft, but a wide range of spring settings are available. Both are a fairly hard long-wearing compound. The two tire compounds are labelled North and East because they would be running in different series North is a 90s Formula specific radial with a stiffer sidewall, East is a 60s generally available car tire - in the 60s road cars would actually run on 165/55s, by the 90s no new cars were using such a small tire.
This means that some aspects of the physics are arbitrarily decided for example, the tires and dampers are wear items and something plausible was provided, since users could replace them anyway. The mod represents one of these as it would run in current vintage Formula Ford series. It's a 50 year old car, of which originally less than a hundred were hand built. However, Alex Francis was no longer interested in the mass production of small-profit chassis and sold the business to Allan Taylor, who produced several more Formula Junior, Formula Three, and Formula Ford chassis in small numbers before closing the business in around 1972. The series proved popular and by the end of the 60s there were a half-dozen manufacturers producing quite similar vehicles, including the Alexis Mk.15. In 19 the Mk.14 won multiple national championships in Formula Ford. The main difference in the two was the Renault transmission used in the Lotus, which frequently failed, until the 51b replaced it with the same Hewland transaxle that the Russell-Alexis Mk.14 used. Their primary competitor in 1967 was the Lotus type 51, which was a modified Formula Junior chassis.
In 1967, the Formula Ford spec series was finalized, and Jim Russell worked in concert with Alexis to manufacture one of the first series-specific chassis, the Russell-Alexis Mk.14, which were used at Russell's racing school. Alex Francis and Bill Harris formed the original Alexis brand in the 1950s to produce small open-wheel vehicles for Formula Junior.
