can I modify standard donor chassis and still be IVA free
Hi I am working on a design using standard Vitara chassis to build a narrow body 2 seat roadster locost type.
Basically building off parallel Vit main chassis rails using a pref weld on / or bolt on sub-chassis comprising Bulkhead/ double hoop rollbar and body
frame. Keeping as light and simple as possible welding on would make triangulation easier make it stiffer.
I want to use it on low springs with suitable tyres and with front axle and shafts temporarily removed ( The Vit design makes this easy) as a track
day car and on tall springs/shocks as an off roader.
It would be nice to do the shopping in it as well so tax it IVA free on standard chassis.
So now the big question how standard the chassis has to be.Keep standard axles,brakes,steering,engine gearbox, fuel tank all easy!!!
Do I have to use original body mounts in original position Id rather not?????
Can I remove outriggers????
Can I move back bulk head????
Seat belt anchorages are on body on Vit so presumably would be just subject to MOT!!!!
I understand any answers would just be an opinion but any opinion would be welcome.

I beleive any modification to a chassis requires an IVA. It is written clearly in the manual but cant open PDF's at work so cant look it up.
How long can i resist the temptation to drop a V8 in?

The rules mean you can't add or particularly remove bits of chassis. Small mounting brackets OK, but nothing more.
Of course you could tey the odd bit, as long as it looked original, I doubt any inspectors would be able to spot every addition etc, but bolt-on would
be a safer bet.

tbh those changes are trivial and would not be noticed. I use to change the design of the outriggers for my landys to make them stronger (scaffold
tube rather than sheets box's) and was never mentioned at MOT's. If you want to give yourself hassle and pain then tell the DVLA then find
yourself trying to get an unpassable car through an IVA.
If you want to have an easy life and just get the car done then just change what you need as in reality no one will give a sh&t. It reminds me of
the guy who made his Golf a gull wing and then stupidly told the DVLA! ended up having to put it through an SVA and lumbered with a Q-plate!

Thanks everybody for what we have so far just the sort of experience I was looking for but here is a thought
DO I HAVE TO TELL DVLA "keep the colour the same."
Seriously though I can imagine going past an ANPR equipped interceptor Cateram taxed as a vitara nik nik nik but if its insured as a kit car are there
issues around this does a rebodied car have to be notified to DVLA
I know to some these are basic questions but my experience is in motorsport with the RAC blue book the rule is if it doesn't specifically say
you CAN do it then you CANT.

You don't have to inform the DVLA if you have rebodied a chassis based car, so long as you haven't went crazy and chopped several feet of
the length...
For example I could take a landy and drop a escort bodyshell on it and so long as the colour was the same not an issue, this only applies to cars with
chassis and there is a limit to how many items you can swap all at once.
One tactic I adopted was to change one thing at a time on the car, for example change the engine number, then send the form back for a change of
colour etc that way no one at the DVLA goes oh look at all those changes!! must be worth looking at.
Tbh I hear of these things going on all the time where cars get brand new chassis and retain the orginal reg and the DVLA are never informed and what
sane person would??? take beetles, loads are getting new chassis, but how do you replace the chassis on a 40 year old car, as if that's going to
pass an IVA!!  answer = you just keep quiet

Thanks for that Mr Whippy I am changing it quite a bit visually from hardtop Vitara to locost type roadster but chassis basics track/wheelbase and all
associated metalwork will be kept standard.If I have to bolt mount it I want to change type and position of body mounts and cut off what I don't
use
I want to spend my money on car rather than paying VOSA and DVLA so dodging IVA is prefered I am using donor off road as is with mild 2 inch lift
Rover springs etc and plan to build car in computer first then build in steel during the winter

HI Yes donor has no back seats or belts
Insured as 2 seater
But your post just made me look at log book very interesting most of the items are blank there is an item number of seats including driver but it is
blank.
Body type is Light 4x4 Utility could be an issue

Going back to the Landy's I don't think the seating is an issue. I have had station waggons that could sit 7 that were changed to pickups
that then sat 3, hey their landy's and that's what happens with them. Not once did I have issues with the MOT or DVLA. I think the same
will apply in your case.

Hi Mr Whippy
Thanks for that just spent ages lying under vitara on my back.I will be able to use the original body mounts.I am going to build a sub chassis/roll
cage/body bolted to standard chassis like the NCF but much lighter cateram type. I will just MOT no IVA but use IVA build manual so IVA free but hedge
my bets just in case!!! and insure on my trade insurance policy which allows kit cars and engines up to 250hp without separate approval.
That should get me on the road still wonder if I should change 4x4 utility body type to open sports but maybe it would stir the DVLA hornets nest.
Will build in computer first just for fun/play with donor off road and build the thing in the winter.

You are right of course Volvorsport that settles it. Now back to wrestling with CAD modelling a standard Vitara chassis always
wanted a hobby GRRRRRR!!!!
