Theo, question about your wheel/front end set up. Do your wheel stay tucked
into the fender or do they overhang outside?
I ask because I'm going to get a front cross member from Mike (Toyz Junkie)
and put 5 lug hubs on the car. I am also planning to use a 16x7 wheel with
similar offset of ~40mm. Given Mike's cross member custom nature I can set
track width however wide I want. I did some simple math and to set the
outside edge of the tire the deep offset vs with wider wheels that put the
outside edge of the tire in the equitant place if running stock track width of
the custom front end. Here are my simple calculations of a few standard
wheels. (Note these numbers are based on rim width and offset and not a true
measure of back/front space because it doesn't include the rim lip)
Wheel-------------offset--backspace--front space
Panasport 15x5.5--19mm----3.5"-------2"
Panasort 15x6-----22mm----3.9"-------2.1"
Mustang 16x7------40mm----5.0"-------2.0"
The primary question given your comment about 3/4" spacer is if I can set
track width of the Front End that much wider than stock and still fit the
15x7" wheels with 40mm offset inside the fenders, or will they stick outside
the fenders? I'd like to get the wheels out as far as possible yet still have
them in the fenders to have longer control arms for better suspension
travel/leverage.
Thanks for the info
dan

15x7 should work even with untrimmed fender lips on the rear of the car,
provided your wheel offset is correct. Panasport has a size that is
supposed to fit. On the front it's more tricky because there is not much
clearance to the front lip on the fender and the lower valence. I am
running 16x7 wheels front and rear, but the fender edges are rolled and
the lower valence is trimmed to allow all that to work. The critical
interference with 16" wheels (on the front) is that the rim inside edge
can contact the upper control arm and balljoint as they move through the
suspension travel. I used redrilled stock hubs and ended up with about
11/16" or 3/4" worth of spacers between the hub flange and the wheel
(which is a 2005 Mustang OEM wheel, 16x7 with 39mm offset IIRC). If
you're using 15" wheels then the upper control arm and balljoint would
contact the inner tire sidewall if there wasn't enough spacing.
Panasport has a 15x6" wheel that has offset compatible with the Tiger
but I don't know if it will fit untrimmed fenders.
