using a siearra sub frame rear????
Hi
Apparantly there are some plans available that use the siearra sub frame at the rear wich sorts out all the problems working out how to make rear arms
and hubs etc. Has anyone seen or herd of these.
Grateful for any help or pointers on how to do this for myself

the robin hood 2b also uses the sierra rear.
it would be a BIG job to adapt to the locost design.
search with google for robin hood engineering and see what comes up.

Mathew,
I have an article & some drawings by a guy called Colin Lourie up in Edinburgh. He adapted the Locost chassis to use the Sierra subframe.
It looks fairly uncomplicated. Let me have an e-mail or an address and I'll send you a copy.
Regards, Ian.

I think the most important point here is why would you want to? The sub frame is not ideally suited and it is rather heavy plus the complication of
adapting a locost to mount it would be at least equal if not more that making a proper double wishbone irs rear end.

the biggest problem I found when I looked at it is that the front of the sierra suspension mounts via two large rubber mounts. These are tall and eat
up a lot of height at the back corner of the chassis. It also pushes the wheels a long way back unless you chop a lot out of the bottom rear corners
of the chassis. If you can see a pic of a robin hood 2b frame then you will see what I mean.
Although a sierra rear end is heavy, a live axle isnt exactly light. It takes a lot of time to do an indy rear, and there is a lot of scope to get it
wrong.
Having hind sight, you save a lot of time using a live axle. The original '7' didnt exactly handle crap, and anyone thats been in the Isonblade and
poste don here does not seem to complain of duff handling - just hairdo problems!

Mathew,
Agree with Mr Gusterson.
If you insist on IRS, and on Ron Champions car, buy the Avon book as well, and incorporrate the IRS design into the rear of the chassis.
It's what I've done - but is as yet untested!!
Have a look at this:

If you look on the locost club site(www.locostcarclub.co.uk)under help there is a sketch of how to adapt a locost chassis to take a sierra irs sub
assembly.Looks like a sherman tank tho!!!

one thing about the sierra suspension it gives a lot of bump steer ,maybe alright in a seirra but how it would effect a lighter car like a locost i
dont know
but it makes rwd rally cars very twitchy in the forests

Ian,
can I have a copy? I'm rapidly painting myself into a corner and this would be greatly appreciated.
Cheers,

Just had a look at the stuff mentioned above on the locost car club site.
(Here) The front outer trailing arm bush is going to either eat into your
cockpit space or stick out the side like it does on the Robin Hoods and its got to be unnecessarily heavy. Surely it should be possible to fit just
the trailing arms and not use the massive cross-tube.
Editted to say: I think the 'Why would you want to' above is still the best answer.
