Hello all,
Im in the planing prosess of bulding my kit car baced on the haynns chassis and a mx5 doner car and have rerad about oyher bulders macking there car
wider ond longer as this givs a bit more space in the cop pit and makes it easer to fit seat ect just wanted to know how they would have keept the
wheel bace the same? or is it as simple as making the rear wish bones that bit shorter?
Plus any other advice would be grate full thank you all.
To make MX5 running gear wider you would need bolt on CV joints and add spacers to them or custom made half shafts. Another way round it is to use rims with near 0mm or -20mm off set.
ok thanks for that
I did not thnink any one would reply
People always reply. . . Even if just to tell you that some one will reply!
I would suggest not changing the wishbone length as this will change the geometry. Widen the chassis.
Have to question do you really need to lengthen / widen it?
The Haynes Roadster is already fairly big as 7-esque cars go.
While there are some widened versions of the original locost about, I can't think of anyone off hand that's widened the Haynes.
You'll also cause yourself a load of grief with body work as none of the off-the-shelf scuttles/bonnets/nosecones will fit a widened chassis.
Might be easier to just narrow the transmission tunnel if you really do want a bit of extra width for seats.
The mx5 outer CVs are not designed to be separated. They are essentially fit and forget. I abandoned them and started down the route of using
replaceable sierra xr4x4 outer stub axles and bearings in the mx5 rear upright. It is possible with very minimal machining. I have not finalised
the details as the project is on ice but I now have mx5 rear uprights with a replaceable/upgradable CV joint, I will have to use a custom driveshaft
and also will need different wheels front and back. The cut and sleeved shaft is only a mockup btw.
Whilst my experience is not really applicable to your situation, it is related. If you find that the mx5 rear end requires custom shafts I would
seriously consider using a sierra rear end, shafts and uprights instead. There are some downsides but its 6 of one and half a dozen of another.

Much better off with the Sr2 from Roadrunner. Designed from day 1 with MX5 donor.
Proven design, top quality and cheaper than the Zero
I didnt think MNRs were that badly priced, especially for what you get in terms of parts not just quality.
I think its about £4k for the starter pack but it includes loads more ontop of the GBS kit (£2645) like fuel tank, shocks, brake/fuel pipes, steering
rack and more.
And from what I saw at the Donnington Kit car show I think you need an extra drive shaft as they mount the diff so its more central, different
mounting aswell they appear to have cut off the long "ears" of the diff case use 3 holes in the top to bolt to a plate, not sure if the
holes are already there or drilled.
According the the website the SR2 price is £4K plus vat (£4800) for the starter kit http://www.roadrunnerracing.net/the-starter-kit.html and does seem
to have a little bit less than the MNR kit.
wow just checked price list out of the sr2, it better be good quality at that price! 4k+ for chassis starter kit plus 2k for bodywork! It most certainly isn't cheaper than a zero!

I agree about the Mnr, the mazda vortx starter kit at 3.5k is great value as it includes bodywork too. Unless I'm reading the price list of the sr2 for the same package you are looking at 6k+?? I like the Sr2 but not at those prices.

The starter Pack includes the bodywork, they have a choice of 2 additional kits to add on with the extra electric bits and donor prop/upright modifications,etc.
Personally I dont like the hinged combined bonnet and nose cone, prefer the separately removable bonnet and nosecone cant seem to see an option offered for that though.

The prices I used was just on their website, not on their official price list, from this page
http://www.roadrunnerracing.net/the-starter-kit.html
I hope its not 2K extra for the body as thats way too much, as I think you can even get the Westfield Mazda SDV (Single Donor Vehicle) kit for
£3150inc vat (Not £4k) including bodywork, and I know which one I would prefer, mind you still need a lot of extra stuff ontop of that. They do an
additional kit for £5200 with everything else (Quite literally everything), although you could save loads by sourcing stuff yourself and not fitting a
screen etc,
The MNR price is misleading on their website, I think they have put it up but forgotten to update the website correctly in one place its says £3500inc
vat but if you got the module page it shows it as £3950 which I think is the price they quote at shows now, so good value for what you get I think,
seems to include every bolt, washer, rivet, nut you need.
