lol, yes lots........ the 'new' book is much better written BUT I'm not sure the end product is actually an improvement (ok
it's a bit bigger which can be handy). One is based on MK1/2 Escorts, the other Sierra but again I'm not entirely sure that's as
much of an advantage as it used to be.....

I agree.
Didn't Caterham designers shy away from an IRS because they couldn't design an effective one in the 9 months they had ? The went de deon,
when the live axle was no longer available.
It would be interesting to see one on track and the times they turn.
Although considering the input of Martin K, he's had a few years experience under his belt now

It's not really about that it's more the availability of parts..... there are still loads of specialist Escort breakers about because of
the rally aspect......no one really cares about old Sierras. OK you can buy Sierra uprights cheaper than you can Cortina ones BUT that's about
it..... and tbh it's not really a problem to get your hands on a set of Cortina uprights even now

No, I meant when Caterham had to go away from live, because they couldn't get them new.
BTW, there are three Escort specialists within 5 miles of me!

Lol, I know - but I was trying not to reopen a HUGE can of worms Live and DeDion axles are lighter overall (greater unsprung weight though) and
much easier to get 'right' BUT not fashionable/modern so people think they're rubbish (rear disk brakes are the same - you
don't actually NEED them but cos 'sports cars' have them........) and the 'can of worms' just carries on from there

Yes - BUT the suspension would need altering. If you have a Sierra sat on your drive build a car from the new book cos it will be much easier - and it
will be a good car. If you don't have a Sierra sat on the drive you will have more options (bodyworkwise especially) with a
'classic' Locost build

Thats the situation I'm in now, ron champion book locost but sierra front hubs and 200sx rear (IRS), it can be done but as with everything, the
road less travelled is harder! If you don't have a chassis yet, I would suggest choosing one or the other and building a kit to suit, much
simpler.
A bird in the hand....

I think it depends on what you are going to use the car for, cruiser or lightweight racer.
I am building a car to be fast on the track so I'm a bit bias.......but
From what I understand the geometry of all of these wide independant cars (I mean compared to the Westfield they were ripped off from) are wrong for
their wheel base due to their use of original length Sierra drive shafts (to keep costs down). Westfield in their wisdom created their wide front end
to compensate for this problem and some other 7's have wider front ends than others. These I consider to be 'cruisers'.
The original narrow Westfield SE live axle narrow and wide (and the narrow independent with custom drive shafts )
are thought to be some of the best of breed. The original book being a bad lesson in measuring your mates Westfield means that if built properly with
a few simple tweeks the original 'Locost' is the one to build If you want a fast light weight car that can be properly setup and
'work'.
Other points for a Locost are:
Its dead easy to get the parts, I could have built 3 from the parts I spotted on Saturday at Retro Race
The english axle is good for 250 BHP (which is enough for 7 type car unless your just driving in a straight line) and it easy to get ratios for
Loads of backup including bodywork parts and knowledge
People have done it all before and can help you with any problems (I think the site is called www.locostbuilders.co.uk......)
And the most important thing is; I think it looks MUCH better than the Haynes roadster
One thing I would advise is buy a decent chassis unless you are good with a welder

Making my own chassis might as well as i tig weld for a day job

I'd previously missed this. Have you been assimilated by the Matt-borg?
