actually,the tweak adjustment can be done with tweak screws in the side plates.we havent been running the tweak screws though,we have been just running them without and i havent needed to check tweak on the car.i used to check it when i first started running it but it has never tweaked yet so i stopped checking.the only time it tweaked was when a front arm screw bent from a good crash.i changed the screw and the tweak was gone.i will show you the car at minnreg.you will see what i mean when i tell you that you dont need to worry about tweak.
if you wanted to run side springs you can always use the IRS damper tubes that allow that option.i havent needed any added spring tension though.
