Based on the original ISI/Studio397 1967 Howston G4, modified by woochoo & mantasisg.
Inspired by a classic 1967 endurance race in France. 55 cars, with 29 unique sets of physics, aimed at capturing the vibe of cars they may or may not resemble, and able to provide the variety of multi-class racing on a grand French circuit.
Now includes some 1966 cars as well.

v2.0 now on workshop
Mantasisg has worked hard to produce a more representative physics set for each car type. v2.0 now includes the different wheelbase/track, some updated suspensions, some improved engines, and some more representative inertial characteristics of the different car classes. GT cars in particular will feel much improved.
The body meshes have also been updated to better represent the cars, with better results due to the more accurate wheelbase and track of each car. The body meshes are styling-cue bodies, rather than replica bodies. A central cockpit mirror has been added, and the wing mirror types are customised or removed to better visually represent each car. Custom steering wheel textures are also included where appropriate.
Now also includes a cockpit light to indicate the wing position of cars 7 & 8, the two cars with giant movable rear wings. Instructions for binding a single control to activate both front and rear flaps for car 7/8, and also tips for using the cars with adjustable wings

v1.51 on the workshop: minor update to address classification errors

2018-08-18:
v1.5 on Workshop
Classes have been implemented to help opponent selection, and results classifications.
All of the body meshes have been minorly adjusted with some styling cues.
Some liveries have had minor updates.
Modified wheel meshes for all cars (the same mesh) with custom wheel colours per car.
Also, the 7.0L white cars, #7 & #8, now have a giant rear wing, which can toggle between high and low downforce. That works in conjunction with a theoretical front flap to maintain aero balance in either setting. Some text editing is required to bind both front and rear flaps to a single button or key.

UPDATE v1.402 (2017-08-01)
Following the Studio397 update to the G4 (to v1.4) for Dx11, I've updated my G4 1967 Endurance skin pack. IT NOW INCLUDES ONLY THE G4 (no G6), and OLD VERSIONS OF THE SKINPACK SHOULD PROBABLY BE REMOVED because they might conflict or confuse.
The new version of the G4 1967 LM-esque skin pack now includes 29 unique sets of physics, aimed at capturing the vibe of cars they may or may not resemble. These aren't perfect physics adjustments, but they are able to provide the variety of multi-class racing on a grand French circuit.
With some research, the new physics have: adjusted weight/inertia; engines; gearboxes; fuel tanks; aero; engine sounds. All cars maintain the standard 1967 G4 suspension, track/wheelbase, tyres, and body shape. The slower cars still have the original G4 fuel tank size and consumption, which might help them in multi-pitstop races.
If anyone is interested in doing further work with the physics or models, please contact me
Additional engine sounds are from other s397 cars
Contains some adjustments to meshes, materials, and textures
Includes RCD Talent file
Car pit groups assigned to work with Le Grand Circuit 1967
>> Car #150 is listed as Front-wheel drive, but in testing the driving was so poor that it was returned to rear wheel drive (would probably require work on the suspension etc, which is beyond my capacity at this time)
>> Missing engine sounds for some of the S4 engined cars (a technical oversight when packaging - will be updated)

And thanks to ISI / Studio397 for the base car and sounds
===== ===== ===== below here is old news ===== ===== =====
An update is planned (for 1967 & 1954) which will include texture adjustments for the tone mapper changes from earlier in 2015, and will be repacked as a single cmp including sounds, which should solve any problems some users might have with sounds not loading from the original ISI Howston cars. No ETA, but sooner rather than later. It turned out to be later, and here it is, just below...
EDIT: UPDATE to v1.301, which is based on the updated ISI Howstons (v1.3), and includes the engine sounds, and has had the skins tweaked for the game lighting that was updated in 2015. This should now be able to run without the ISI Howston G4/G6 installed, but won't overwrite them in any case.

Hello Howston Drivers!
Following on from my 1954-inspired skinpack for the G4 and G6, I've made a skinpack inspired by 1967 endurance racing in France.
The 54 liveries are available for the G4 and the G6 (that's 54 for each), and the pack includes vehicle filters to run the G4 and G6 separately or together. There is an extra opponent filter to run a particular selection of G4 and G6 cars in a multi-class G4/G6 event ("Howston_G4G6_1967_Endurance_Entries").
Some minor tweaks have been done to the Alpha channels of the skins for the reflections.
A basic talent file is included.
As with the 1954 pack, the 1967 pack will work in combination with the original ISI Howston cars (which are required to be installed). Nothing gets overwritten.
I'm probably not going to do any other skinpacks, so if anyone else wants to, you should
