So you sold your Ultima, what do you build next Answer is !
Discussion
Well after playing with the 962 for a couple of years I have a little more understanding of under body aero. Not by any means saying I’m now a aero expert but questions I had over the 962 rounder leading edge at the very front and what seemed like a squeezing of the air instead of a flat floor before the diffuser now make sense to me. It’s all to do with the stagnation point in front of the car, the point at which the air has to make a decision to under or over the body. The air going under tends to separate from a flat bottomed car so you loose control over it. The way you get it back is to add rake to the under surface of the car, this then regains the air so any diffuser at the back then becomes effective again... A 962 is flat And has very little rake if none at all but it removes any chance of a boundary layer forming by pressurizing the air as it goes under the front. This then gives you a much better and earlier chance to start Accelerating the air with a longer and now more effective diffuser. To many I know this might be boring but to me it was a lift bulb moment, and meant Some minor changes the front splitter and under the side pods area might help my goals of a proper working ground effect car. So I’m excited to get back to the body work stage now this winter.... once the snow starts falling here then I’ll be happy as a clan working back on the old girl...
Had to do a quick wheels alignment and camber adjust before committing to the wheels positions for the body work. Trail fitted the doors just to be sure there was nothing to far out I have to correct..
Next step is to modify the front splitter to the new design to help aid the under-body aero, and aid the lessened rake the car now has. After that I can really get the car's body finalized for molding....

Well apart from the fact my chassis is taller, wider and has a Longer wheel base than a GTR, err no..... No Ultima parts will find there way into my garage any time soon. As much as other things have kept me busy over the last few years, (962's and moving home/shop ) I'm feeling the need to finish my car and get some road fun back into MY life. I will be building another 962 for sure, but this car needs a happy ending and now I have the space I can keep more than one car build going at the same time.
The more I get back into the build the more I realized I need it to be finished for my own sanity as well....
Anyway Happy New Year to you all

Final alteration to the rad frame, and the start of the Wood Buck for the splitter.... Filler tomorrow then paint before mold can be taken... 
Looking goodWhat's the idea behind the turnbuckle in the top wishbone? I assumed it was for caster adjustment but it looks like your wishbones are bushed so you can't run any misalignment on them anyway?

Rubberized joints on chassis pickup points allows for a few degrees of adjustment. Also have adjuster on the top ball joint to adjust camber on the fly... Once I’m happy with the setup the next set will be fixed.
Yep the camber adjuster looks good, just my experience of rubber bushes at anything other than bang on alignment can bind and cause stiction. But they are the right solution for a road car for sure. Not nit picking just curious as I've been through all this recently with my racing car trying to get enough caster was a nightmare as there was no angle built into the upright to begin with..!dom9 said:
Start a thread for the tube frame and link here please, Clive! The last one was awesome. Assume this will be very similar in design?
Fran Hall does a 962 these days, doesn't he? Assume that uses a variant of his welded aluminium chassis.
Been a while since I spoke to Fran but as far as I know that never really got of the ground. He was borrowing the molds from the same guy we used with our 962. They cost more to fix than to buy..Fran Hall does a 962 these days, doesn't he? Assume that uses a variant of his welded aluminium chassis.
