I know this has been discussed over and over, but honestly after reading all the post and replies on the subject myd head is about to explode from information over load.

before I shoot my wad on this setup does anybody know if fitment will be issue.

1968 Charger, current stock front end components, stock disc brakes.

what I would like to change up.
Tires

235/40R18 Fronts thinking 4.5 BS?

275/35R18 Rear 5.5 BS?

any better ideals appreciated.
Again thanks for any input

All things on car are stock components if it makes any difference on fitment.
Hoping this can be done so I can put this to bed lol.
