That's Roadster Shop's SPEC chassis for the first gen cars. Ask me how I knowIf it’s unibody why it has another frame under?
sorry for stupid question because of my ignorance
Yup. Classic cars cost a ton to make into a racer that keep pace with the other built classic cars turning into racers.If you want to drive the car, early Mustang stock suspension (especially the front) is completely terrible.
But I would just buy something from TCP, Griggs or Ridetech for the front and leave the rear suspension alone. Maybe if you really want to mistreat the car add in some subframe connectors. You can get by with cheap disc brakes in the front and stock drums out back. If you want to lower the rear either rebuild or buy specific leaf springs for that. I wouldn't bother with a conversion to a fancy multilink setup in the rear.
My answer is no you don't have to spend that much, but it's going to be expensive. FIgure out what you want and add everything up before you start. Decide if you really want to go down that road.
But I would also encourage you to make a cruiser. Don't try to build it into a race car. I think that will cost way too much money. Use a modern car for track days, not a classic.
I drove my 86 bronco for the first time in about 2 months today after driving only my bike and my 2022 mach 1.Or leave it stockish and get a feel for what we old timers had to drive when we were young.
