 Topic: AMX or Javelin tested stopping distances?Posted: Aug/05/2021 at 6:41am |

Just got done doing a total redo of my 69 AMX brakes, complete system. Rebuilt KH calipers in front, rear drums w/ new slaves, new lines, rebuilt differential pressure switch valve, new rear hold back valve, new pads. I wanted to know if anyone has stopping test results from the 1968-73 period for an AMX or Javelin? Looking for maybe a motor trend or hot rod test from that time. I'm just curious how the rebuild stacks up against "as new". Of course it will all need to be taken with a grain of salt, since I've mixed technologies on my car from different time periods and other factors such as weight, tires will influence the comparison. But none the less it would be interesting... also it will interesting to see how it stacks up against todays cars (gulp)...

'68 AMX 60-0 in 115' with power discs. Outstanding back in the day, and darn good 53 years later! I believe that was in a Popular Science test. I can check. |

no way 60-0 in 115'. more like ~150'. A lot of this was the tire technology at the time.

Thanks Trader. Holy Cow. I realized that number was apparently copied from a published test but I'm just a little skeptical.... Well, regardless I can guarantee before the rebuild it was no where near that (my Zo6 is about 60-0 in 100 or so feet and that will literally put you thru the windshield). I'll do some after rebuild testing and report back when done. Also, my car is a manual master so that will likely influence it some...

I seem to remember Motor Trend had the 1970 390 AMX distance at 122 feet. At least, that is what comes to mind. The 1/4 mile time on it was 14.68 at 92 mph.

Stopping distance from what speed? Some of the magazines that listed stopping distance did it from 50 MPH, so it can be easily confused - I've done it. The difference between 60 MPH and 50 MPH stopping distance is 30+ feet.
Sports Car Graphic, one of the few magazines to test G force and stopping distance: 1970 AMX 60-0 in 146 feet. This is looking at the actual magazine. Right now. Not something that someone typed in online. edit: 390, PDB car I posted about this years ago, but maybe SCG did a 70 test of the TA "street cars" and the 50-0 stopping was over 110'. I was very impressed. Until I later realized it was from 50 MPH

60 mph from the Motor Trend article on the 70 model. Usually 70 mph stops were over 200 feet from what I remember.

I mentioned in my post above that it was indeed a 60-0 stopping distance (and I was off by 4 feet!) Yes, it was Motor Trend, not PS. And holy cow, IIRC nothing but an AC Cobra could stop any faster back in the day! |

60-0 results from SCG for 1970: AMX: 146 ft, .74G cornering, lost oil pressure on cornering, A mediocre experiment, terrible brake balance- rear lock up LT-1 corvette : 140 feet Z-28: 140 ft AAR Cuda: 140 ft Porsche 914: 149 ft Mach 1 429: 149 ft Lotus Europa:133 ft Gremlin 232: 201 ft :) Firebird TA: 138 ft Camaro Trans Am race car: 122 ft ( .96G cornering!) At the time, no other magazine tested handling and braking as thoroughly as SCG did. Because essentially no one else tested either. SCG did skidpad G measurements, stopping distance... in the 1960s. Both the Boss 302 and Z28 stopped better than AMX or Javelin- better brakes and bigger tires. SCG on the vega: There are so many innovations made merely to reduce the number of pieces and improve reparability. that it can't possibly work" :) |
