Rolling Chassis Progress updates.

Time for a progress update. The beast has finally received its rear wheels and has made a bolt for freedom. The front wheels are still being built and should arrive shortly but the words “Breath”, “Hold” and “Don't” are being used widely here. But with the rears fitted the whole beast can be pushed out into the fresh air for an overall progress shot.

Rolling Chassis - 05/2010


The Beast Makes a brake for it.


And also a chance to look at those “Sex on a Stick” wheels. P.S. the fronts are standard Sierra wheels from a scrappy, just to get things rolling. They also show the size difference between what was and what is going to be required.


Now That's a Race Wheel


These wheels are not only sexy but bloody massive, causing chassis to rim clearance to be a tight but well calculated "phew!" moment. Hey don't those big discs look small now!


Not Much Room For Error Then.

 

The 8" rims carry a massive tire width that should get the power down to the road surface and grip as the G-force builds, but has taken every millimetre of the calculations that were made for the chassis and wheel spacers. In fact they are 4mm further out than the original calculations, not bad for a CAD/CAM package and tyre guide website.


On the 27/05/2010 the front wheels arrived.


The Completed Rolling Chassis.


Front View of Rolling Chassis.


This picture clearly shows the low sump and is the reason why the SAAB engine would not suit some of the ground hugging or small wheeled kit cars (Lotus Seven styles etc.). This engine suits a high mounting position with suspension, bodywork and aero designs used to keep the handling under control. Besides, the whole engine and chassis is still lower than and road going SAAB, even those with lowered suspension. A SAAB 9000, 900, 93 or 95 that has been lowered will give 4 inches of ground clearance between the (big bore) exhaust and road. The engine is still some 4 inches higher up in the chassis than the lowest point of the exhaust. In this chassis the sump is the lowest point with the exhaust higher up inside the bodywork. This all adds up to a much lower centre of gravity. Add to this the near 50/50 weight distribution of this cars rear wheel drive set up and weighing in at around 650KG along with massive tyre contact, the handling (once fettled) should be astonishing.
