There has been many discussions on the tune of a car and whether
or not it affects it.
It is also confirmed that Tune A, B, C and D of an integra all can
achieve 2:34 on irrohazaka (last stage). So does tuning make any
difference? Some may argue yes, some may argue no. Even at the top
levels of internet rankings, people have differnt views.
However, having said all that, the things worth changing are carbon
fibre elements (like your black bonnet, black side mirrors
etc).
There are also discussion that wheels make a difference on wet or
dry conditions. Not to offend anyone but i personally dont see any
difference. It is the tire and thread patterns on the tire and
compound of that tire that makes a difference in real life and in
the game, since we are only changing the wheel, there shouldnt be
much differnce. As the wheel doesnt come into contact with the
surface of the road. But a lighter wheel does improve the
performance of your car (in real life) but not sure in the game.
However, you might want to try to go for VOLK racing wheels option
during parts change should it come up.
So perhaps, just go with the changes that you feel affects your
driving positively and makes your car look real cool. and if it
doesnt, next time just change back with the parts change option. If
you are hitting the top 10 times in the internet rankings, then
perhaps tuning may come into effect. If you are within the last
1000 rank, then it probably wont because changing a spoiler or not
on your car wont reduce your Akina time from 3:0x to 2:50
seconds.
Hope this has helped.
