Bro...if u wanna play low end/drag u better stick with the 4.75....I think comparing the 2 FDs 4.4 will be more comfortable to drive...we you go on highways u won't have that irritating high rev...which if i'm not mistaken will suck up fuel more than a 4.4....
In terms of stifness is ur Spoon absorbers very stiff? Coz usually its the suspension that makes it stiff....as for bushings, it may play a part as well....how did the car feel prior to the bushings?
As for tire size, if can better to stick to the correct size, and if u go for 15' or 16' better use 205... with 16' you can go max 50 series i think....60 or 65 series i doubt will fit...looks weird too...even 55 may look big...can ur wheel arches clear this size as I presume your car is also lowered...
