Good information on chassis selection and motor mount suspension is hard to find.

Some useful pointers from NSR

Some good info from Black Arrow

Slot.IT  manufacture suspension systems, even magnetically levitated systems,  but I can find no Slot.IT specific information on setting up the suspension. 

Chassis and Motor mount suspension in general : 

-Lower grip surfaces require softer chassis.
-Higher grip surfaces require harder, stiffer chassis.
-Bumpy and uneven surfaces require softer suspension
-Glass-smooth surfaces can use harder suspension.
Often a compromise setup has to be found (eg a slippery but bump free surface)

A soft spring screwed down harder is not the same as using a hard spring!
Further generalised recommendations are hard to figure out because each manufacturer uses differrent numbers of spring mount points.
(NSR use 3  slot.it use 4, thunderslot use 5 )


Full Size racing cars often use hard suspension but  not  because it improves cornering. 
The suspension is "hard" (in f1 for example) to keep the aerodynamic components where they are supposed to be in relation to the rest of the car and the road .
At full size, high speed,aero is  more important to the road holding than the suspension.

Front end suspension systems
- drop arms 
- sliding sprung guides

I've not found any good sources for how to set these options up so if anyone has information, please post. 

There is far more to suspension design than I  will ever know.
Experimentation and track time is required to figure out what works for you and what does not. 
Keep a log of suspension settings for each car and note how small changes impact the road holding and handling.
Only change one thing at a time 

Please feel free to comment and throw rocks.
