My interior upgrade plan
 

Zeta IV x2 2160
MA harness bar 600
sparco 6PT 3" Aluminum harnesses x2 980
Sparco quick releace 330
Sparco R345 or R325 250

I am still thinking about the harness bar and seats, I think the MA has the best harness bar but I have seen a more beautiful bar before but I just can't find. For seats I am think about the Zeta iv or the new stradia3, stradia 3 will import after 3,4 month. How is full bucket seat for daily drive? any imporve for the plan?

For the seat. How tall are you and what is your weight. The height matters if you are planning on doing any trackdays. And the weight gives an idea on how wide you are. Before buying a seat. You should try and seat in one before throwing money at it. Because if it doesn't fit. you will be miserable with it.

These things should be thought about one at a time, especially if you haven't used any of that stuff. Just like the wing, how do you know for sure you need this? Obviously these are more track-oriented, but is that really what you're trying to do with this car? Are you really committed to making an actual track car or just improvising with things you think sound nice as you go?

Have you thought about how your steering wheel is going to affect the reach to the shift paddles? Living with the loss of some button controls? Or like Rusty said have you at least looked into the seat dimensions?

We see you posted here with stuff you think you like and prices. We don't know where those ideas came from to give constructive feedback. Looks like you just made a some Christmas toy wishlist. Nonetheless you might get a Christmas tree on your dashboard.

I am 183cm tall and 185lb fat, Where can I try the bride seats? however they have just one size for the zeta4, my seat has to be Bride.

I am not that supid yet. I will track it but am not making a "track car" but also daily and keep adding stuff on it. I am so OK to drive without buttons on the steering wheel. The shift paddles is a good question but I see its ok with sparco streeing wheels

bride seat has only one size

So you're a runt at 6ft. Now with wearing a helmet. You now have to figure out your seat mounting options. Pick the wrong one. Your head will be hitting the roof.

My head was hitting roof with helmet with Oem seat, how is those seat feel in daily?

I think you mentioned this was still a street car for HPDE right? If it was me I would not replace the steering wheel unless it's a dedicated track car. Also if you intend to use the harness do it only with a helmet and HANs device. And if you want pull the airbag fuse at the track.

listen to this post or you may die.

:iagree:

I can chime in on the seats. I don't recommend a full bucket for a daily, especially if you're over 30yrs old (rusty is about to make fun of me for thinking that's old). I eventually got sick of getting in and out of the car all the time with the extra bolstering. A reclinable bucket will cost much more, but that is your best option for beginner track use and daily driving.

Agreed. Fixed back racing seats blow in traffic.

And the reclinable racing buckets usually aren't FIA certified, which would be a requirement for someone who is safety conscious.

True. It may give them some extra head room if the OEM bucket is too high.

Another option is to just swap the bucket in before track days. I did keep my FIA seat for that reason.

I can see the most important thing is the roll cage, Leaving oem steering wheel with air bag stay in C level or get a roll cage and Hans system to get in B, is that correct?

yes my oem hit my head with helment

You realize that you will have to wear a helmet AT ALL TIMES in a caged car, right? Otherwise a fender bender may leave you even more brain damaged than you are right now. A caged car on the street is a retarded idea.

You should do NOTHING to the car's safety systems until you have a good deal of track experience. Stock seats, restraints and airbags. Your skill level is below the car's capabilities, so no parts other than a set of brake pads will be required for you to make the most of your track time. Once your skill level comes up you'll know WHY you need things, not just that all the cool kids on facebook all like these mad tyte seats yo.

Don't ask us. We're not authorities on this stuff. Find out what shops near you prep cars for heavy track use and go talk to them.

Also, be aware that harnesses and a lot of other safety gear has an expiration date. Don't think that the stuff you buy is going to keep you safe for the life of the car.

Take the advice of these guys. They are trying to keep you from meeting your ancestors before your time.

how about adding seat, cage, and harness and keep oem steering wheel with air bag for the first step?

I already did wheel tire pad rotors

No cage for a street driven car. Cage and helmet goes together. No helmet, no cage.

Look at the Porsche GT2/3/4’s. They have optional cage from factory, but only back half, not the front half of the cabin.

I think you should not spend a dime until you've done a shitload more research

Starting with looking up your local racetrack and signing up for some driver education with a professional

Also, meet some local track junkies and pick their brains

and don't buy a seat until you've sat it in to test fit.

You don't get it. Just spend your money on seat time. Get enough skill and speed to warrant a race seat, harness, harness bar or 4 point roll bar. When you are fast enough to compete or times fast enough to do so then you can go hog wild. Oh get a fire extinguisher!

Install the roll cage on the outside of the car and you'll be good to go :twocents:

how about this one? It says legal on road and only back haf without front. Can I use it with helmet In track and without helmet on road? Is this still available?

It's your car. You can do whatever you want. I don't know why you insist on continuing to ask questions about parts that people have already told you that you don't need yet. Spend your money on seat time. You'll need things like an oil cooler and fuel starve solution long before you have any need for a roll cage.

I suggest you check out Facebook if you just want random strangers on the internet to validate whatever decision you make no matter how dumb it is.

"You'll need things like an oil cooler and fuel starve solution long before you have any need for a roll cage."
Good advice.

Otherwise, why not be nice?
He needs time to think things through.
Let the man ask all he wants. It's a free country.

I'm just pointing out that it's pretty clear he's already made up his mind on what he wants. So why bother trying to convince us that he needs stuff he doesn't need? He can go check out the roll cage threads if that's what he wants.

Read thru the thread you linked and you’ll have your answer to both questions on safety and availability.

You want a cage? Like others have suggested, go talk to a road race shop, get some first hand knowledge.

Why do you think you need one? I don't have one in my car and it is due to one reason. It is a street car. If I get into an accident without a helmet there is a good chance I will crack my skull open without a helmet. No thanks. it is my opinion is you need a roll cage, you need a helmet and other safety gear to go along with it. Do what ya want. Some folks put it in there.

He should already have all the info he needs to start digging and think things through.

The problem is, he isn’t showing that he wants to think things through. He’s skip counting without learning all the numbers, and he hasn’t realized it yet.

Great question. Dr. Phil and an empty couch please report to exam room #1!

I have a 4 point bolt in from RPM. For me I feel its safe enough on the street, only a bit of the center section has any possibility of me hitting and its SFI then foam padded. At the time there was no good imo harness bar available, now I would have gotten the MA one. Just stay away from the autopower crap and ones with bolts on the cage itself. The chart i showed earlier is a very good tool but its not detailed for every situation. Any extinguisher (mounted not on the A piller) along with gloves and shoes would be a good investment. Also a mic/headset like a chatterbox is helpful to hear your instructor. Also before you get to the track have someone check your work last thing you want is to not pass tech.

I ran a RPM 4 point for many years and had it removed for a full cage because my Z will be a dedicated track other than hard parking it at car events. It is a quality roll bar. Next Level performance makes a similar one. At this point we seem to be preaching to the choir!:rofl2:
