Please don't forget that Quattro Sport was homologation spetial. It had 
to have present all parts that were not found on regular Quattro Coupe 
but were to be used on rally car. Example is homologation spetial of my 
Celica had water injection  which is really not needed for street but was 
to be used  for rally by factory.
Quattro Sport also had double plated suspention pickup points and front 
strut brace. It was hand built and was intended to legalise all these 
extra parts. Also it had a pipe that ran from upper strut pickup point 
down and forward, in front of oil pan and around to the other 
side. Because suspention pickup points are usually tied into cage if 
possible, this pipe was almost a part of thge cage. It is this pipe that 
control arms are tied to with rosejointed links that our fellow lister 
saw on the picture of the "dirty side".  All this was done to the rally 
car to stiffen and strengthen the shell in order for it to survive the 
stiff 5" spring suspention. All properly built Audi and other rally cars 
follow this logic. When budgets or rules are limiting factors and shell 
prep is not complete  one is forced to use softer suspention and adjust 
driving style or else damadge the mounting points. If mountin points are 
reenforced but the shell is not adequatly stiffened or if too many 
mounting points are not tied into cage, the shell will worp. This is why 
it is recomended to put rally cars on frame puller and true them up 
periodically even if they are not damaged. Top ProdGT drivers in SCCA 
Prorally routinely do that and finde major bends. Rally control arms from 
Audisport are painted blue and made of tubing. I was told that it was 
chrommoly. I had opportunity to buy them but had no use and didn't. I 
have seen chrommoly subframes on Audi and many other rally cars including 
factory rally version of my Toyota. One Audi rally driver with 
fabrication capabilities prefered use of stock stemped steel control arms 
without links so that in case of colision with large potholes only 
control arms are bent and damadge doesn't spread to subframe and shell 
which are not strengthened enough to take it. The same driver once bent 
lower arm and than chained it to a tree near by and pulled it out by 
putting his car in revers. It was not pretty but he made it to the end of 
stage and replaced it at the next service. This is a more practical way 
for a privateer.
I hope this is adequate explanation. This is not laws but opinions of 
peope that were and are my mentors in this sport. I learn something new 
at every rally and on every stage and service stop. Most amasing ones are 
in England where I am going this fall again to spectate RAC and look for 
builder for my rally transmission.
