It started with 5R002 and Shelby team driver Ken Miles, at Green Valley Raceway, Texas.
And by "started", that means it was the Shelby's very first race outing...and win!
As you can see, Ken Miles was hammerin' his car...and all the others' on track!
The story began here at the shop where the Shelby Team was building a number of R-models.
And there was this curious idea for an independent rear suspension set-up that the Team never completely implemented on track.
Take note of the transverse leaf spring set-up, using an idea from the Cobras. Also curious, it appears the left-side lower link is bent. Evidently, it was not meant to be in the '60s. Perhaps the Ford "suits" perceived the concept as not "feasible"?
So, are your ready? Then, fast forward 50 years, to February 2015...
...and the first public appearance of the 1965 IRS R-Model Shelby Mustang, 98i! The "i" is for IRS!
The new IRS Shelby suspension.
What follows here is a photo essay of the re-born G.T. 350 R-Model IRS and its unique elements...

Rear disc brakes on the IRS.
A completely redesigned racing valance by Pete Brock.
New, significantly larger, high-flow rear brake cooling ducts.
And then, stretching legs around the track:
Out of turn 9.
