The plot thickens on the TVR 400R. Only 7 ever built for competition. It appears the first 3 at least built in 2001 indeed have the smaller dims which it seems likely is the same as TVR Tuscan road car and what tech-racingcars.wikidot have quoted. The last 4 which I gather is the 2 Chamberlain and 2 LNT cars have the larger dims listed here:Let me explain.
From what emerged from my research, the TVR Typhon/Tuscan T400R/T440R are practically the same car whose name has changed over time. So the blueprint with the measurements (the one I posted previously) is valid for all three denominations. The first thing I did was to measure both models in length. Once I imported the models into blender, I measured them:
360 gtc/modena by RSS--> 4.48 m (0.026 m less than the real Ferrari measurements)
TVR converted from GTR2 without modifications --> 3.90m (50 and more cm less than the blueprint)
TVR upscaled --> 4.42 (0.02 m more than the blueprint)
Let's say that 0.02m are negligible margins of error, 50 and more cm are not.If the GTR2 model was exactly proportioned, the other two dimensions should also be approximately correct. Unfortunately, as you may have noticed, only the width is slightly off (1.85 over mirror against the upscaled 1.87 and 1.77 against 1.90 upscaled*) . The only thing I can think of is that the model isn't perfectly proportioned. The other element that makes me understand that the measurements in the blueprint are actually his is that the wheelbase coincides with the upscaled 3D model (2.574 brought to 2.58 in AC for that 0.02 difference in length). If the length coincides, the wheelbase as well as the height, then I assume that the model had to be upscaled.
As for the wheels, I have to explain myself better this time too. The dimensions were deliberately increased to avoid clipping with the asphalt (beta version) because I had already enlarged them in the Tsunoda version trying to respect the measurements (by doing the upscaling they became larger, now I have already fixed them with the right measurements).
Having read that in GTR2 there are several errors in aerodynamics, physics, etc., I wouldn't want them to have also been made on a graphic/measurement level.
EDIT: let's be clear, I don't want to impose myself. I've just checked and experimented several times and I've come to this conclusion.
*1.90 refers to the width at the rear, the widest part of the car. Tightening it by 0.12 it would no longer have the over mirror measurements, so I assume it has been widened in the racing version or in any case it is not exactly like in reality.

length 4367 mm / 171.9 in
width 1880 mm / 74.0 in
height 1210 mm / 47.6 in
No reference anywhere to the wheelbase spec but you assume it has to be longer and your picture previously mentioned is the only one that is quoting a wheel base.
Check this page if you haven't already, you can really see the difference in width from the photos between the earlier cars and the later ones.

So it appears there are two versions raced.
How I checked your model size was in CM by making the inertia box fit the car:
INERTIA=1.990,1.2,4.435
My GTR2 model has the earlier width of 1.81m and wheelbase of 2.361 but it is a bit short, longer then 3.9 but around 4.1.
We can now assume that SimBin modelled their version off the earlier race car.
You could safely scale your model back a bit to the quoted 2003 spec.
As for tyre clipping the tarmac, getting the model size close to what is listed in tyres.ini solves this issue.
All I need is the a.i to be much faster around that 1 corner...
The certain thing is that I can scale the model to fit the 2003 measurements, but I won't do it right away. Since this car is constantly evolving, I will downscale from 4.4m to 4.3m when I am sure I no longer have to touch either the 3D elements or the LODs.
