26mm TRC fits the car with original suspension, after doing the front c-hub king pin mod. 28mm TRC/Jaco requires shocks to be moved in to inner holes on the a-arm, along with little mod to rear sway bar holder. And yes, you can true/cut the tire/rim down to what ever width you'd like, but it does take some grip away. Jaco used to make 24mm foams, but everyone's gone to 28mm. Just get the 28mm, and shave them down to fit your car. I don't think you can go wider then 25mm with LW suspension though?
