What do you plan to use as body panels, Ash, kitchen film maybe? Nice one.

Simply hang the Z-cars type frame from a well-bolted-in rear roll bar.

what about a suzuki capaccino thingy.
There was a bonkers one reviewed in PPC about a year ago. It had a busa lump in which is sweet as the manufacture is all the same, good pub banta!
Track days ARE the best thing since sliced bread, until I get a supercharger that is!
Please read my ring story:

I assume by RWD you mean engine behind the front axle and RWD. I've driven good handling examples of both rear-mid engine and front-mid engine.
For a car which engine accounts for a significant % of the total weight, I choose rear-mid.
My Ultima, for example, gives me the feeling that the engine is sitting where it should. My Locosts, on the other hand, felt like the most effective
way to take a bend involved making them oversteer in order to place the engine right between the rear wheels and the target direction, then push the
engine from there, so to say. You end up using the rear wheels for steering, which, in a car with that layout, makes sense from a physics
perspective.
On cars where the weight is more spread because the car itself weighs a bit, like for example my MX-5, front-mid is alright.
Looking at it purely from a fun perspective, I agree front-mid is fun, specially in sevenesque cars and similar, in which you often find yourself
describing circles around the engine since the driver sits pretty much on the rear axle

615 kg but I agree it's a pretty cool car. I didn't know there were quite a few GRP monocoque cars, in fact I only knew about the GTM line
up and the Mini Marcos and Midas Gold.

wonder how much an elise would weigh without the K series and gearbox??
All these weights you quote do they include car engine and box?? obviously a bike engine saves a fair chunk of weight, a 5vy R1 complete engine weighs
in at 65kg

If you have already bought the classic mini transfer box it's a bit late, but if you haven't I would suggest you turn your engine the
correct way round and use a jackshaft to a more normal chain driven diff, this will give you more weight forward and too the right, if you want to,
and also let's you use a long chain with plenty of room for an electric reverse aswell
This is the style of jackshaft I bought for a previous project

Mine is the same track /wheelbase as an Elise and the z cars Monte Carlo is very similar , smaller than that especially track would be hard work to
drive on the limit . Mine is just over 800kg but has a good chunk of weight up front

just answered my own question, K series engine with nox is 130kg, so you save 65 kg straight away.

All those weights are for stock cars in standard trim, so a finished project would weigh less. In the case of GRP monocoques, the weight loss would be
mainly from the power train. In the case of steel bodied cars, it would be the power train, plus replacing the bonnet and maybe some other panels with
GRP, side windows with policarbonate, you know the story, then again these would get a spaceframe for rigidity and safety (as shown on T66's
Fiat 126) or at the very least a rear subframe, so who knows.

Well, a standard Elise S1 is 725 kg, and S2s are around 860+ kg.

a bog std. pug 106 is about 760kg (s1 4speed) - and it could loose a bit easily enough
or the citroen ax is even lighter (same running gear)

On the subject of the Z cars mini's, why do they handle so badly? I've heard/read it several times, but as has been said they've got
a lot of adjustability built in, surely they can be made to handle well?
On another note, my vote goes with the Busa cappucino!! Great suggestion!

Which GTM are you referring to, there are several different cars? The GTM Coupe weighs around 610kg with an A series engine and box. The original
Cox GTM was weighed at 533kg (with 10 inch steel wheels etc).

IMHO - I fully anticipate twitchy handling with the Fiat, happy to turn in rapidly but also swift to snap into spinning oversteer at the drop of a
small hat. My car is different, built for fun, thats about it.
Only my own take on why the Zcars are not brilliant on a circuit, but weight distribution is the key here, linked to that , a sensible wheelbase.
Mine has the weight distribution of an old 911, the wheelbase of a Fiat 126, and lots of power hopefully. If I was building a circuit racer, I wouldnt
be where I am, MK Midi / Riot/ seven type of car would be my choice.
BTW - Take a look at your Ultimas front suspension, then look at mine.
I suspect the differences in bodyshell weight are academic , as mine consisted of side panels and roof, it could of easily been an Imp/Mini or Smart
mounted on my chassis. Thank you Nat & Cal....
