Westfield Aerorace - road going, competitive sprint car - Reduced to 15,995

June 28, 2023

1998 Westfield SEW Aerorace - road going competitive sprint, hillclimb and trackday car

A road legal Lightweight Aerorace SEW chassis and an engine built with wide torque band and punchy top end. This car excels on the racetrack but is also a pleasure to hustle down the backroads.

Having owning the car since 2018, this already championship winning vehicle has since helped me secure 1st in class victories in 2018,2020 and 2021 and as well as overall champion places of 2nd in 2018,2020 and 2021.

Following a chassis up refresh in 2015 the car has been maintained and worked on by Northampton Motorsport. Over 15k has been spent on development in the few years to increase performance, reliability and make it suitable for large GP tracks such as Silverstone, Spa and the Nürburgring.
