To help people who wanna to change a seat

[jayliu.jiayu@gamil.com]

First of all, it is not safest way to do the seat until u combo

1. seat and bracket
2. harness
3.harness bar
4.roll cage
5.hans
6.helmet

as lots of common said.
i am totally agreed

but i have no problem pass the local auto x event as stx class
and local track"not racing just training use as they said "
the only thing i changed is the seat with no side airbag on the side and the stock seat belt working same as before
so u lost side air bag for sure, and people said it also not safe during the roll over"dont understand that part".
anyway, just sharing my experience for buying a seat.
and help people can study some thing from my mistake.

Hi all

over a past month for change the seat that wut i got


1.test fit
if u know someone already had the seat installed in their car, go test it out for the fitment. this is the most easiest way to find out ur size
and planning ahead for the harness if u wanna one, cause some of the seat come with the hole right under ur leg and some of them not
the main different which is 4 points harness or 6 points harness.
the seat with hole is for 6 pints harness, with out is for 4 points.
i recommend pick a seat with hole so u can easily change it.

2.pick a seat
u need measure ur waist and upper body for buying the right seat for u, i did my by test seat whatever the seat i can find, then i ask the owner which brand is the seat and which series is belong to, also the size for the seat. after that, i was searching the size on the internet for the seat i was testing. u should have a pretty good idea on the size for ur need by know at end
for example u should find something like this and pay attention on those number i had circled. that is the most important number for fit ur body, car, and bracket!!














3.find a bracket

once u narrow down the seat u wanna buy, u should looking for the bracket now, this is the most important part over all the process.
a good bracket should let u seat as low as the floor, and center with the steering wheel.





keep ur eyes on that number, this is how u know if the bracket will fit ur seat or not.


for the bride seat, they don't give u that number for any reason
buy i found when u go to their home page and select the seat u wanna, then the next task is for pick a bride bracket where they will told u which one will fit ur seat and ur car. very helpful info
http://bride-jp.com/en/seat/

















now u should had a good idea on the bracket size



4.harness
the harness is the most important thing for ur safety

there r a lot of rules, some of them asking that angle. some of them r not.
i am not respond for any safely issues






first of all, get ur angle right. follow the local track requirement.
and either buy a harness bar or mounting the harness on the chassis

i keep my stock seat blot and not really using the my 6 points harness
so i end up just using the hock on the top of the rear seat where there is a baby seat safety hock





the one in the mid had hock behind the rear seat from factory too
anyway
angle is one thing

harness bar is another
and hans is the important too





if u really get all them working right

here is my tho just give u a idea





for the side part of the harness,
i drill a hole at transmission panel and get the the hock blot installed on the right side
and take that factory seat blot cover at bottom, u will find there is the hock for factory seat belt, and i just hocked it in there.






the most difficult part is the lap part.
their is brake line and chassis structure right under the point for my drill point.

















i guess it is cause they design it for left hand drive maybe
i end up with the cusco seat brace.






it fit perfect, but it may off the angle a bit, just a bit.


by the way, the stock seat belt should run thought the left side hole on the seat, my seat just fit me perfect or a bit tight. when i seat in the car, the stock seat belt fit me perfect like before.


here is the stock seat belt bracket








6.buy a resister

which is 3.3ohm u can get it in any electric store and tap for warp the resister





the drive side is very easy, nothing but the resister and take out the wires from factory seat

the passage side is not,
u need take all the above and also a pad between the stock seat and bracket, that is for trigger the air bag for passage side.
then u put it under ur bucket seat fiber pad.

here is the link who is explaining better than i for sure





7.need a zip tie
for clean up the harness and the wires under the seat


8.hardware
a lot of things come with the seat and the bracket in the package


a)but u still need 4 spacers to security the factory bolt for the chassis





b)1or3 large space for install the harness, this is goes under the car so pick something that not going to rust out. and apply some permit coating after u tight them up.




all in all

hope this is going to help, i study that in the hard way
bought one sparco ergo and sparco bracket and seat rail, which i find out it just too high, even higher than stock seat. i don't recommend it at all
so i bough another nagisa bracket which i really love it, but it was not fit my seat, just a 5 mm.
so i sold the sparco seat and went buy the bride zeta iii type L
compare those two seat, the bride has a better quality for sure
much better!!!!


i am 183 cm 42 waist with 90kg
my seat is bride zeta iii type -L
harness is sparco 6 point
bracket is nagisa double locked seat rail

are harnesses street legal in canada? If I was ever to get a bucket seat, I'd wanna use the stock seat belt.

Also follow the harness mounting instructions. The shoulder harness rear mount point doesn’t look right to me. Is that per the instructions? Angle appears too high.

Plus, harness without a half cage is generally considered unsafe... definitely less safe than using OEM 3 point belts.

A fixed seat and a 6 point works well without a cage, until you crush your head, a 4 point works well till you submarine and find yourself in the foot well.

Yeap, some good advice on fixing a seat.
