Mad Mechanics Kit Cars Forum
New and secondhand parts for Ferrari, Lambo & Maserati. New parts appear expensive but they do a very good deal with secondhand parts.
Wheels 'n' Tires
This is a link I use frequently for checking the different tyres and wheel sizes that will suit my vehicles. Means I don't always have to replace like for like (some tyres can be rather expensive) but instead can change tyre configuration and maybe find something which can be same or better quality/performace but cheaper.
Stinger pics and info
Link to a Fiero forum with some nice pics and build details for a "Stinger"
