The Moto-build front splitter looks very good. Was it the Elise MkII one you fitted, and how much modification was necessary?
What tyre pressures did you settle on?
I went with 28F/36R and didn't play around with the pressures because the weather was so poor.
The splitter is specific to the TF and is a very tight fit. I believe it was moulded from an original MG Sport and Racing item.
