Thanks for that heads up on Simpson Design. Did you see the prices they are asking? The USA is clearly a different market!
They are using a Miata (known as MX5 in Europe) which requires them to make some compromises. I thought all their types looked a bit "chunky" as a result and I was particularly interested in seeing their Italia 2 GTO which looks a bit like my 275/Z3 project based on a Z3 (see my thread at
http://www.madabout-kitcars.com/foru...ead.php?t=5207 ) I am still finalizing the design so I will take note of their efforts and try to benefit.
