haynes roadster & locost wishbones ?

[thenorthface]

i have just bought a chassis off ebay and was told it was done to the locost book, i was wondering if the difference between wishbones are the uprights you use ? roadster for sierra and cortina for locost ? are the chassis mounts in the same place ?

The Locost chassis is totally different to the Roadster chassis,

for starters The Roadster chassis is 2 inches wider & 4 inches longer than the Locost,

The Roadster is an IRS setup whereas the locost is "Live axled",

Or.... have you bought a "Roadster" chassis but has come with Locost wishbones?

Do you have a photo of the chassis? very easy to confirm from a photo.

Front wishbone mounting points are very similar, I think the haynes wishbones are something like 3mm wider iirc. I think they may a little longer as well so result in a wider front track, not too sure on that one though.

I'm using Haynes front wishbones on a locost chassis as I wanted to use the better sierra uprights. I had to make my own alignment tool to fit the brackets to the chassis, but this was no more work than making the normal haynes one, I just had to make a few more measurements that's all.

Also, it has allowed me to match up the width of the front and rear track, as I'm using a BMW E34 rear axle assembly, that is very wide. But that was just to suit me really.

sorry for the poor photos the chassis is in storage for awhile until i move house,

Doesnt look like a roadster to me. Similar, but bits are different.

It looks like this chassis has been made to accept IRS, but its not a Roadster rear end, the suspension boxes ( CP3 & 4 ) are different, as is the positioning of parts D12, so maybe its a locost chassis to accept IRS ( slightly less chassis width), the front frame is also different & it looks like its been built to accept a bike engine.

Looks nicely put together
