Brand new rear calipers in steel and alloy!!

PostPost by: bigvalvehead » Wed Nov 23, 2016 7:54 pm

I should shortly be able to offer rear calipers now being remanufactured in steel and alloy!!

Steel weight is 2.6 kg
Alloy weight is 1.1KG

A useful saving on unsprung weight as well as overall weight

With donor calipers now becoming increasingly difficult and (more expensive to find and £160 +vat to refurb) most now over 40 years old these will be viable for FIA race cars (steel) and non FIA road and race cars alloy. The handbrake components are currently in production process.

rather interesting... Shall I understand that the alloy version of the Girling 12 would probably not be FIA compatible though Girling NR is?

then in the same vein, are you also considering (or are aware of a source for) an alloy version of rear bolt on hubs ?

thank you for your continuing effort to add more lightness !

Hi Nic
The Girling NR is not FIA compatible.

I have seen them used in the USA but are not accepted here.

I think Kelvedon do alloy hubs but again not FIA compatible.

Cheers

Hi Dave
Thank you for the precision, for the rear I had just forgotten, as checking on the net a 2014 specs from the FIA site states
"Lotus 26R
- For Period F, GTS cars, dry sumps are not admitted.
- Lotus Elan in Period F, Homologation No. 127, may use Girling AR Mk2 or Mk3 callipers on the front brakes."

I'm not quite ready yet to establish the proper light bits list, so I can still work on the budget prevision - which definitely needs to get lightness added...

As for rear Hubs from Kelsport, I had seen multi drilling steel bolt on hubs (RACERHBO), but not alloy... They offer front alloy hubs (RACEAFH and RACEAFHS depending on stub size), and other places as well (e.g. Triumph GT6 type) - but then you're saying alloy hubs are out, both front and rear? I was thinking going the bolt on option then compensate with alloy hubs as a compromise: acceptability by FIA is something that is not so obvious to anticipate it seems, it would be useful to have a reference document more detailed than what can be found on the FIA site...

In any case, I'm potentially looking for a pair or rear hubs (I just have the hand brakes bits for my racer, missing the Girling 12 calipers themselves) - will have to figure out whether it should be steel or alloy... then possibly swap with the rear brakes of my street elan.
