steering racks
i was wondering: with so many cars around, couldnt there be a substitute for the escort steering rack already? i mean, couldnt a micra or fiat
cinquecento one work for example?
is it because the steering arms need to go in front of the hubs rather than the back for a locost?
i dunno, find it hard to believe only the escort one is compatible.

i imagine we could get cheaper and possibly better items from a scrappers and a more common car? there are not many escort Mk1 left.

on a book build the hinge points on the escort rack are too far apart hence the bump steer issues with locosts. The majority of current racks are
designed to work behind the front axle line therefore theyare geared the wrong way. I suppose you could mount them upside down depending on how the
oil seals are good for this.
It is time to rethink the locost concept to use entirely modern car parts however this would almost unavoidably make it a front wheel drive or mid
engined design because it is moving away from the Lotus 7 basic design. If you want to keep on the Lotus theme you could look at the Europa that was
originally designed around the front wheel drive mechanicals from the Renault 16, these were a north south set up rather than the east west
arrangement that is almost universal now.
As time goes on the emissions issues and electronic engine management will make the problem of using modern vehicles for kits or self build worse.

The Miata (MX5) is already a relatively common donor in the US, and the old ones are getting quite cheap over here. Not quite down to Sierra prices
yet, but won't be long.
Then you have a selection of BMW's, Merc's (190E's are very cheap) that are thus far a relatievlt untapped source of RWD
components.
Personaly I love the styling of the Sylva Mojo and I reckon the next "Build your own sports car for an unfeasably small amount of money"
manual should be mid engined like the Mojo. That opens up the choices of engines and boxes to probably 90% of the cars on the road today.

You can use a RHS rear-steer rack flipped over in place of a LHS front-steer rack
