Hey guys,
Thanks so much for the positive feedback. There seems to be a lot of negativity towards putting 18's onto a Torana!
The back are 265/35/18 and has enough room to fit 275, possibly even 285 without scrubbing. this is without any tubbing, The guards have been rolled.
I never thought you could go that wide without flares but its definitely possible.
Front are 235/40/18 which is the same rolling diameter as the rear. They clear the firewall seam (which has been folded back flat) but slightly scrub on the rolled section of the guards but only at full lock and on uneven ground.. so Im pretty happy with that . . . . .
