The Cat c660 Truck?
Geese, its either a commercial truck ad on this form or the game of stripped Asian teen women out of their cloths with a water blaster in the rain forrest with your keyboard.
Yeah, sadly there isnt much for the crz. With a few mods you can make a gen 2 insight a 10 second car for the 0-60 claim of the crz, but that was considered slow even for an entry or eco level car decades ago.
Although Id think you got better aero, I guess the extra .3 displacement really hinders better mpg. I think the former owner of this site hyper miled a crz back when they came out to over 100 mpg.
I drove a cvt and stick one. Cant say I liked either. The stick runs out of gear at 35mph and the honda dealer told me I didnt know how to drive the cvt model.
Otherwise do all thats suggested here. Grill blockage, lowering, less rolling resistance and adjust the nut behind the steering wheel.
