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?
