Hello all, I am planning on building a R1 powered clubbie, and thinking about what chassis to build. I have designs for caterham, haynes and orginal book.
1st thing, I would like to confirm widths to make sure I have the right information

Caterham - 1000mm (approx)
Haynes - 1118mm
Book - 1067mm
(driver compartment width - outside to outside of chassis)

2nd - Saturn body work, which chassis is it designed to fit?
Do you recommend this? Is there other full body suppliers?

3rd - What chassis dimensions would be best suited to a R1 clubbie?? Plan is to build a very light, simple vehicle.

Thanks for your help.

I can confirm the Haynes is correct at 1118mm

Saturn bodywork is also designed for the Haynes.

What sort of rear axle are you going to use?
ie Live or IRS?
Start there!

Book chassis is made for Live axle, and would need shortened half shafts if going IRS (Sierra rear axle)

Also if you are a Bat F'Stard like me, you may want a Viento Sized chassis (Book +150mm)
Or a McSorley (Book +100mm) if you are a bit slimmer

Collins Chassis

McSorley 7+4

McSorley 7+442

'Book' Chassis

Rorty IRS for 'Book' Chassis

(Wont let me attach file, but thinking about it, you should probably get these from Rorty personally.

Thanks for your help.

The plan is to do an IRS. Due to me living on Australia I can not get easy access to Sierra parts. So local parts will be sourced to fill what ever I choose to make.

As with bodys. I want to buy an off the self item. Cause I have done custom body work in the past and dont really want to do it again. I saw the Saturn stuff and liked how it looked (on the net) and the colour choice.

And I guess finding a body is important cause this will determine the chassis.
Any advice??

Being in Australia complicates things as you need engineers to sign off on the strength/rigidity of the chassis.

For the original book locost there is a document that contains the 'Australian modifications' required to allow it to pass.

I'd suggest you talk with people who've got a car on the road down there before investing in a chassis.

This might be a good place to start

I was going to design my own chassis to ensure it pass's the test. I was hoping to get an idea what chassis would be best suit to a BEC and then design my chassis / suspenion around that. I was also hoping to get some more information body work suppliers, cause this will also affect the chassis dimensions. I am only a light weight so designing a chassis around my body frame is not required.

It wouldnt be hard to design something based on the attached by modifying thechassis from the rear bulkhead backwards.
