The suspension of EB1821 was initially set up very capably by Group 2
Motorsports of Seattle, but repairs undertaken after cracking the front left
wishbone on a test at the East Anglia Classic Rally in April of 2007 required
that I revisit the suspension setup. For this work, I turned to Pat Thomas and
his team at Kelvedon Lotus in Lincolshire.
