hello everyone and welcome in this video
we're going to be talking about five
modifications which are some good ideas
to do as the first modifications for
your car and so you know there's there's
a lot of different things you can do to
a vehicle and not necessarily in any
order we're going to be discussing these
um but one of the most important things
you can ever do so number one is tires
and if you've watched this channel then
you've heard me ramble way too much
about tires so I'm not going to get into
it too much but basically tires dictate
everything they dictate your maximum
acceleration your maximum deceleration
your maximum cornering and so you know
of course you need power in order to get
maximum acceleration uh but you're not
going to get that if you don't have the
traction to do it so tires are the most
important modification out there braking
acceleration cornering they change
everything if you haven't yet I'd really
recommend watching my video what is the
best mod um where I talk about the math
behind this and why tires are so
important 10 times as effective in
certain scenario versus adding power and
so that's just kind of crazy to think
about uh so the next one I want to talk
about is brakes and I think there's a
common misconception about brakes uh
that you know upgrading your brakes
means you can stop faster you'll have a
shorter stopping distance that's not
really the way brakes work brakes don't
dictate your stopping distance tires do
and so if you have brakes that you can
slam on them and the wheels can lock up
that means your brakes have enough force
uh to stop your tires from moving and
that's all they really need to be able
to do and in order for you to have
maximum deceleration at that point it's
your tires that become the limiting
factor so if you want good stopping
distance you need nice tires brakes the
purpose of brakes is to turn kinetic
energy into heat so your car is moving
you hit the brakes and the the brakes
heat up those brake rotors heat up and
as a result your car slows down and so
the the thing that you want to do with
Brakes in order to improve them is
either improve the cooling or improve
how much heat they can retain so you do
this uh through design or by the size of
the the brakes so if you think about a
large Hill and you're at the top of this
hill a small brake will heat up faster
and fail earlier while you're going down
that Hill a larger brake will fail later
going down that Hill if you're just
using you know your disc brakes to slow
you down likewise a brake with better
cooling will fail later than a brake
with worse cooling so the ventilation
within it how it's designed is all very
important uh for the stopping distance
uh once you get to higher temperatures
so brake fade is what you're trying to
eliminate by upgrading your brakes this
is especially important if you plan on
adding power to your vehicle or if you
plan on taking your vehicle to the track
uh where you want that extra heat
retention the larger disc brakes or the
better Cooling in them uh so that you
can continuously use them and not worry
about coming into a corner at 120 M hour
and then your brakes failing on you and
you're just going straight at that
corner so brakes are number two uh
number three I'd like to talk about is
an LSD and so putting in a limited slip
differential if you have a rear wheeel
drive vehicle or even front-wheel drive
vehicle can be very beneficial reason
being is open differentials send power
50/50 they have a 50/50 torque split so
what does that mean well let's say
you're coming into a corner and you lose
a little bit of traction with one of
those Wheels well that wheel is spinning
and it's not getting much torque scent
to it so now the other wheel is also not
getting much torque sent to it because
both of them receive the same amount of
torque in an open differential what a
limited slip differential does is it
sends more torque to the wheel that's
spinning slower and so if you've got one
wheel on ice and one wheel on pavement
the wheel on pavement is going to be
spinning slower so your LSD is going to
send torque to that and as a result
you're going to be able to accelerate
better so lsds can improve your
acceleration coming out of a corner they
can improve your acceleration depending
on road surfaces and they can also get
you sideways so there's some huge
benefits to putting in a limited slip
differential if your car doesn't yet
have one uh so that would be my number
three recommendation my number four
recommendation is updating your final
drive ratio this is really a way to make
your car more fun this is what Subaru in
fact did with this 2017 BRZ which we are
in right now is they put a 4.3 final
drive ratio in it versus the 4.1 that
was in it so what does that do well that
takes your wheel torque the torque that
you're actually applying to the wheel
the force that's coming from your wheel
that's accelerating you forward and in
every gear it lifts it by that
percentage so 4.3 divid 4.1 whatever
that is something like 5 or 6% every
gear is going to have that much more
Force at the wheels now at a point this
becomes meaningless you're not changing
the torque of your engine you're not
changing the power of your engine you're
just changing the gearing and so you're
sacrificing top speed for more wheel
torque but let's say you just went from
a 4.1 to like a 5.1 well then you might
just replace a second gear so first gear
may now have the or second gear may now
have the exact gearing of first gear and
at that point it's meaningless you've
just eliminated a gear and you've
reduced your top speed so there's a
certain point you know a certain
percentage where it's worth doing and
then a certain point where you're just
eliminating gears and there's no reason
to do it but you can get more wheel
torque which just makes it more fun
that's why you'll see in performance
packages like on the Mustang you can get
I don't know what it is but like a 4.3 a
4.5 something or 4.7 if you get that 4.7
you're going to be putting down the most
wheel torque you're going to have the
easiest time spinning tires uh and
that's what makes these cars fun so you
know specifically more for rear wheel
drive cars that you'll you'll really
enjoy that uh but you know front-wheel
drive the same thing if you change that
ratio you're going to get uh better
wheel torque and so the final thing I
want to talk about and you know this
one's a little different you may think
why but an exhaust and I don't
necessarily think like getting some loud
exhaust is the smartest thing to do uh
but one of the things you'll notice is
that factory exhaust systems tend to be
really heavy and perhaps this is for
noise levels I'm not really a fan of
super loud exhausts but there are still
quite exhausts out there that are
significantly lighter than stock exhaust
so one of the big benefits of changing
to a lighter exhaust uh is just saving
weight and so you know a lot of OEM
exhausts are really heavy and so that's
a pretty simple thing that you can do
just to reduce some weight from the
vehicle let's get in second you he have
a little fun on this
corner wow it just holds it's
amazing usually slides out there but
this thing just held it good fun uh but
yeah as I was saying you can take out
some weight with the exhaust there and
you're not sacrificing the drivability
of the vehicle so that's one of the
things that I kind of focused on with
this video is you know five
modifications that aren't actually going
to sacrifice your car as far as turning
it into a a track car you're not going
to be losing the comfort of the vehicle
with these modifications which you know
a lot of times you will be doing so
tires brakes uh the differential the
final drive could lower your top speed
and could make it a little bit louder as
well as the exhaust making it a little
bit louder but really all of these focus
on keeping the everyday drivability of
your car the exact same and just making
it more fun to drive and so that's what
I think is important uh for first
modifications they future pref they get
ready for you know adding power and
things like that uh and they also don't
turn your car into this track car where
you know you no longer enjoy driving it
on a day-to-day basis so if you guys
have any recommendations or questions
things like that feel free to leave them
below thanks for
