hey guys welcome back to the garage so today's upgrade we're going to do for the is 300 is going
to be on the suspension now that i've taken care of all the maintenance as far as the oil leaks and
the steering and all those other leaks i get down to the suspension and doing some of the
other stuff that i want to do so what i'm going to install today is what they call these roll
center adjusters if you don't know what they are i'll explain to you guys in a minute so stay tuned
so what role center adjusters are they're basically just spacers that fit between your
lower control arm and your hub or spindle right and what they do is they space it by the thickness
of the spacer and they actually come with longer bolts and everything so you could do that the
reason why we do this is there's a couple reasons for my reason i'm doing a big brake upgrade
and i need the caliper to clear the steering knuckle where the steering meets up with the hub
but other people use it as a lowering method but you basically use that method to lower the control
arm and you shift the shock so that way you get more shock travel i think those are the two main
reasons why they use it i know some other drift guys and stuff use something similar this as part
of their steering angle kits but for my purposes i just need to space it enough so i can get a
big brake upgrade on there and not all big brake upgrades need this for this but this particular
one i'm doing we'll need this because of how big the brembo calipers are so we'll go ahead
and install this on the car now so this kit comes with these longer bolts like i said right there
and they're pretty good oem bolts they got the little hex head bolts on here and everything
so installing the roll center adjusters is pretty straightforward process
you don't even need to take apart your brakes or anything you basically just need to come down
underneath the car take off these two 17 millimeter bolts right here
and once you take those off you can basically swing the whole spindle
up get that spacer in there and then put in the new bolts so it's pretty straightforward
careful not to break your abs line or any of this other stuff these things
remember they have the dowel pins in them you just get the dowels in there line up
the dials make sure they just seat properly i think they're different sizes so they only go
in one direction because of the size so there's an offset for the back side and the front side
get your hardware out so the hardware for these come with
washers little lock washers so make sure you use those
the rear ones kind of off the dowel a little bit so i gotta
use a 10 millimeter
shot it in and actually pulled the dowel in tightly
so now i just gotta torque it down so just to make sure everything's safely
installed we're going to torque these down to the spec of 120 foot-pounds
great
so the install of these is pretty straightforward and easy just two bolts on each side
pop it off put the new one in i forgot to mention earlier where i got these so i got these from
auto sport engineering it's a local company here in florida and it's pretty good stuff i
paid like 77 bucks for these when i was shopping for these i was actually looking at the megan's
and actually ordered them but apparently they back order due to the pandemic and they're from china
so these are actually better they're made locally here in florida and they're basically the same
price as the megan's and they're top-notch quality perfectly the hardware was nice everything
installed pretty easily pretty good stuff for 70 something bucks that i paid for it so one of the
things with the roll center adjusters is you know that 70 millimeters that i added on this what it's
going to cause now i basically dropped the car an additional 70 millimeters so when i lower this
down this thing is going to be tucked so what i have to do is adjust the coil over up here back up
so it's higher almost to probably stock setting and i was looking at this thing and up here this
thing is pretty much compressed with tension even though there's still threads up here to do it
what i'm about to do is unbolt the bottom here spin the bottom cap because the bottom is probably
like three or four inches into that bottom mount so i have to take apart the bottom there kind of
slide the coilover out and then screw it taller so i can bring the car back to a ride height that i
can work with this is going to be way too low once i load this down with the wheels back on hey guys
thanks for tuning in all the way to the end of this quick how-to on installing those roll center
adjusters obviously it's a pretty straightforward install like i showed you and i'm doing this in
preparation of my big brake upgrade for this car now i gotta do the dirty work of adjusting
the coil over so i could actually drive around with this car but i won't show you that based on
all the feedback from my diy videos you guys don't want to see that boring stuff so i'm gonna do that
off camera but that auto sport engineering stuff is pretty good stuff uh they make a lot of uh
2jz stuff and swap stuff and custom-made billet and aluminum stuff so you gotta check them out
i'll leave a link in description for them it's the first time i've ever bought anything from them and
it's pretty good stuff so you know depending on how my builds go and parts i need i might end up
looking at them later on for some parts anyways if you guys found this video useful give it a thumbs
up if you haven't subscribed to your channel to follow all my different projects on all these cars
go ahead and give a subscribe and i'll talk to you guys next time
