Chassis Building 101. Ride Height

[RobNoLimit]

Rob,

Can you explain the same thing for independent suspension set up on the rear? I have been looking at using a C6 based suspension and drivetrain. I know this will save some weight on the SW and pending on the parts it may over all, by spreading the weight of the motor and transaxle or I should say help to balance the F/R weight, along with possibly lowering the height of the weight as well.

Disclaimer: I have very little knowledge with IRS suspensions - but I am rapidly learning. ** OK, so yes. The C6 IRS concept is a good one. The actual transmission is basically moved back to the rear axle, or just in front of it, for better weight balance. And, with an IRS, the differential and it's housing go from being 'un-sprung' weight, moving with the tires, to being 'sprung' weight, moving with the chassis. With my current Cobra project I have found the IRS to be lighter in total weight that a 9" would have been, with a lot less USW. So, over all, it's a win/win/win. Less USW, less total weight, and better weight balance.



There may be a negative, and that's the width WMS/WMS (Wheel Mount Surface) The C6 IRS is like 64" wide. (don't quote me it was a guess) For F-100's we want about 60", and for C10's around 62". For a later (67 on up) you can make tis up with wheel offset, but for narrower builds, it's custom arms and half-shafts, and some other things. So measure it out first.
