Not sure where to post this, but thought I'd let everyone know that Motoiq.com has a series on the Fiesta ST, and now the story has been updated to reflect that the car owner is turning it into a race car. The series is quite interesting, and the newest installment is on removing weight from the car, and adding a roll cage.

PS: I'm not associated in any way with Motoiq.com, but the site is worth a read.
