I came across two photos in my research for M23 and a particular M16C of Reggazoni. I noticed the chin spoiler on Regga's car...  and later came across a photo of Peter Revson's M23 when he won the GBGP...  Since the two types are extremely close relatives, then why does the Indy version need this spoiler and the F1 does not? Any way...just a curious thought. Patrick |

I noticed the chin spoiler on Regga's car... I believe all of them had that chin spoiler on the nose.....also if you notice that most oval Indycars from the 70's had the left side front wing angled up more than the right side. |

The Lip on the 16 was pretty much a standard. Looks like they were trying to introduce a negative pressure area under the nose. I'm not sure that the Indy version of the M23 had this front spoiler. I will check through some reference photos to see if the Team McLaren or Penske M23s actually have this. Rusty Looks like the Indy versions did have this lip also... photos.wildhirt.com/penske/pages/_4150143.htmRusty |

Perhaps, the rising-rate front suspension of the F1 car ended the need for the chin spoiler?

The Mclaren M16c also had this strip down the side of the nose.Mclaren had found that the Indy cars where more effected by air pressure then the road race cars.The cars need to stay even with the track surface not lift(less air under car). The cars only turn left & are on a pretty smooth surface. The M23 was a road race car,turn left & right. Short straights more of like short track car.All the road race tracks where different. Accelerate & brake.Indy cars try & stay on the gas pedal on ovals.
Got to go to a Firestone tire test at Fontana raceway with Patrick racing. It was really an eye opener.They explained to me it was a lot harder to setup a car for an oval track then a road course. The car had to be almost a perfect 1/2 inch off the track surface to run fast.Where a road course you just set the car up for entry to a corner & exit.

The difference in front wing angles from left to right was typical in that era. Remember, the only turn on an oval is to the left, unlike a grand prix setting. Using a touch more front wing or a slightly larger wicker on the inside wing made just enough of a difference to help the car turn in. The trick was not going so far that it pinned the nose, which would let the back step out. Another common practice from back then, especially on a very hot day, was using a 100# stiffer spring on the right front to stand the car up a bit and help it turn without rolling over.
