I obviously haven't read the specific regs for his class, so you may well be right of course :)

We're not allowed to do any lightening of the bodyshell between the hub centres (excluding the doors).

So I can't cut away the splash guards, the bulkhead or anything like that.

The list of (legal) things I have on the list do is;

1. Remove more metalwork outside of the hub centres, including some from the doors

2. Fit lighter wheels (13" split rims on the cards)

3. I have some oversize polycarbonate windows on order so I will be bonding those in and losing the rubber seals

4. Polycarbonate windscreen also ordered

5. Fabricated rear beam. I wanted to talk to Austin Nova16 about the one he made, but I'm not getting any reply from him

6. Fit the lightweight KAD Mini rear discs in place of the Nova drums

7. There's also a lot of tiny areas where weight can be saved, such as shortening bolts, and replacing even more fastenings with alloy/titanium

8. Go on a diet myself, as so rightly identified by Mowgli!

Could you loose the bumper irons?

gotta save 5kg there.

matt, there are none...... there is hardly any plastic left in the front one

unless you've been up close, you just can't appreciate how much work there is in this car

Try and find his saloon WIP on mig, as he's normally on there more often I believe.

I stand well and truely corrected then! My point about the passenger side door bars still stands though, as that is obviously not part of the original chassis! :)

Both of them brace into the strut tops from what I can see?

i don't no if cars need to be logbooked for hillclimb? but on my rally cars msa log book it list's the cage configuration. it states it only has one door bar per side and extra diagonal bar and harness bar etc. would it be a problem if something is listed to be there but isn't?

The one that goes diagonally down at the front terminates very close to the floor, so the the moment from the floor to the mount point would be minimal. So this one could definately be removed IMO. I'd imagine the tube stiffness would make the top one redundant also IMO.

The shell has been lightened already by the removal of seat mounting brackets, so are the regs slightly flexible, or is it a matter of what goes unoticed is ok? Also door/boot seals aren't technically the shell, so they could be ejected.
