Even back in the early 90's WRC the homologation cars were only really notionally similar in most mechanical parts. The shell is the same (but
stiffened/seamed and improved - I heard mention of 1200 hours work on the chassis of the scoobers alone!) and IIRC the suspension geometry (or at
least the pick up points) had to be the same, and the engine and turbo were meant to be the same but of course would be significantly improved but
within the spec of the original car. Shocks, arms, hubs/carriers all different, interior not even close. I suspect it's similar now if not more
restrictive but really the minor differences mentioned above can make a car significantly different to its road going siblings. None of that relates
to touring cars directly, but my guess is it isn't far off.

I had to pop up to the company who were building the current Avensis and Audi touring cars and can tell you there isnt an awful lot left of the
standard car.
he front and rear subframes are separate items as in they are completely fabricated from the bulkheads forward or back. Presumably for ease of change
should they get damaged. The front suspension was all rocker arm based with Penske shocks. The uprights and all suspension components were fabricated
from scratch. God only knows what the cost of their CNC equipment was.
They do still use the EPS steering ECU from the standard Avensis though

I done some work on an ex btcc 1990 nissan primera, quite alot on the car is standard stuff. floor pan only slightly changed. Chassis legs standard
but boxed in. Roof standard. The big changes are in the wheel arch areas. Totally changed to allow for custom subframes and suspension.
