My ex-Broadspeed contact says that a very light single leaf spring was used with teflon sliders between the axle u-bolts. The weight bearing stresses and springing medium was coil over shock absorbers. Broadspeed called them 'helper springs'. He said they also used torsion bars at some point.
I'll ask if he has any period photos. |

Hi, that is right Mike, FIA agrees in the fact that it was allowed to add springs, but the Historical regulations defines "free/ allowed acording to apppendix J" as "you still have to show proof of usage in the period". FIA are also asking about evidence that they used Alloy radiator on the RS1600 in this period. Does anybody know if this was used in the period? Avo |

Yeah I know what a joke that was by any stretch of the imagination. Wasnt it around 50 made in an aftermarket garage, about 20 odd actually sold the rest broken to remove the engines for CanAM cars.

As I understand it, 56 were supplied in Corvettes, 2 were supplied in series-1 shaped ZL1 Camaros, and the rest went to Skunkworks projects.
How many d'ja need, Al? |

So how many in the 2nd Gen as I understand it very few, how many had to be made to homologate?

None in the second generation whatsoever....
I'm not sure how many complete cars fitted with the production option motor were nominally needed to homologate the package into Group 2, either as supplied complete, or as kits of parts for retrofit. Someone on this Forum is sure to know! Now a ZL-1 motor in an RX-7; that would make one helluva Group 1 car.... |

Anyone help with Avo's question regarding evidence of alloy radiator being used in 1971 Gp2 RS1600?

I am pretty certain that substitution of the original radiator by another of different size/construction/materials was permitted. Auxiliary radiators were also allowed, but I seem to recall that there was something in the regulations about the radiator having to be approximately in the original location.
The front rad. that the Imps used was ostensibly the heater matrix, but was still in the front of the car, so the interpretation placed upon 'original location' was fairly liberal. Al, as for the second generation Camaro being allowed to use the ZL1 motor, I can't work it out either, but it must have been on the papers for the second generation car because unlike Walkinshaw, Frank might have been ingenious, but he was certainly no cheat. |

I guess we need to see a copy of the rules from the period, does anyone have a copy they can post? |

OK here are the relevant pages to Gp2 App J 1971
As you can see from top of page 4 it says:- "There is complete freedom as regards the water radiator and its capacity. Its location may be changed provided no modification is entailed either to the outside or to the inside (cockpit) of the coachwork." And here are regs for Gp2 App J 1975 Although other things changed the paragraph on radiators is exactly same. So in conclusion the rad could have been moved and could have been made of plastic, cardboard, aluminium.... BUT, nowadays and for HTPs the FIA only allow modifications that were actually used, so if you fit a cardboard radiator you will have to prove it was used in period. Onus is on you to prove, not FIA to disprove. This is the difficult bit where no photos or written eveidence can be found. Dare I also add that this rule is not consistent.... We know about the Capri rads because of all the period photos and cars that still exist. Sometimes period cutaway drawings and road/track tests unearth useful info. Autosport, books on Broadspeed, etc. From what have learned from Avo's posts, he has presented his car for HTP inspection without rear leaf springs. (Dummy or otherwise, they are still 'main' springs.) My take is that had these been fitted then the question of coilovers would not have arisen. It may be possible to call the FIAs bluff on the radiator issue by just by pointing out the relevant App J paragraph- it could work..... |
