So we've started with a nice low mileage 997 GT3 motor and complete car wiring harness. Have bought a body with most of the panels, and a collection of other 962 related bits and pieces....

We do have some rough plans that give me a clue to the original Tubs outside dimensions, so using them and a Jig built roll-cage that would normally sit on top of the Aluminium Tub we built a rough mockup to check for clearances seating position head height feet positioning and maximum allowable chassis width etc etc. There where no dim's for the axle center lines on the drawing so knowing the WB of an original 962 was 2770mm I had to get an idea of the position of the chassis relative to the axles before I could start doing a Full Cad mockup of the chassis, suspension and engine/gearbox combo. That now sorted its time to start the chassis...

As you can see the only flat part of the underneath of the chassis is under the drivers seat, the rest is contoured I'm hoping to keep as close as possible to the original on this as the best part of a 962 was is ground affects, and that lovely bloody great big Diffuser....


We don't have any diffuser panels, so I will have to scratch build one similar to this...

Spent about 20 hours so far from mocking up body to quick cad drawing, and the chassis you see there....
What molds did you buy ? did you pull your body from the molds ??

More chassis progress. Keeping the box frame so when skinned in ally sheets will look more like a tub.
Have used heavy wall for the rear bulkhead as the engine and rear frame will Be supported from it.

no body yet. MK 1 moulds, they were on ebay.

I will be watching the 962 build closely. they had the Rothmans car at the Philip Island historic classic the other year. Rob Sherrard who also owns the Sauber C9 (not sure which one) also had his 962 out as well. Great to watch them barrel into turn 1 and onto the southern loop. I think I have some photos that I could email you if you wanted.

What are you going to do for wheels and tyres, they are massive lumps if I remember correctly, that was the thing that surprised me when standing in the pit garage looking at them, guessing from memory that they were 18” diameter, 12+” wide with a huge side wall, like a 60 profile or something. Will have to go back and look at the photos to see what they were running. It was around 2010

Yes the rear tires are a headache as there up there in the 28-30" Dia. Enzo rears get us to 28.5", that's probably going to have to do. The other issue being the cars ground clearance, normally runs at a ride of 55-60mm way to low for any road car. So its going to be lifted for street use to say 75-85mm at a minimum.
That means the rear arches will have to be reprofiled, as to how much well we will see when I get the body fitment plates in the right place.... Lots to do but its only F/G and steel smash both are malleable :-)

Lift kit is on the cards, probably one of Frans 4 shock units.. Going to make sure we have 2" of droop on all corners so we can lift it to around 5" all round when needed.

38.1 x 38.1 x 1.6mm is the majority, 3mm wall thickness at rear bulkhead.
38.1mm Dia Seemless x 3mm front shock towers and diagonal that the towers connect to help move the load out to the dash and front bulkhead, and 25.4 x 1.6mm bracing. Cage was made from 45mm x 3mm....

Mocking up the engine install, the original car had the motor at a down angle to the front of the car. That's as far as I can tell was mainly due to the gearbox and possibly to help with the diffuser.
We can have the engine level to the floor as the gearbox is different, and that will mean horizontal drive shaft angle....

Needed to workout how far apart to put the bulkhead to adapter plate bars, center to center will be 880mm so that plates going to be a little pricy... The third bar that comes from the top of the cage is fine on the right side but it hits the Oil tank on the left. So alternatives to a std tank might be sourced, or we may just have to modify the original and reposition the hose fitting that's also in the way.



I've marked the area that needs to be cut out to miss the brace...

Design of the Front motor Mount plate is done. Did a quick MDF template on the Mill to confirm the Hole positions before doing the full design...



Now I can confirm the last 2 Tubes that I need to put in the bulkhead as they have to line up to the top outer holes on the plate.
