Upgrade air suspension air lines - help needed

I'm running on Ksport basic air suspension system with 2/8" air lines and I would like to upgrade to 3/8" ones. And my question is about brass connectors. Do I need new ones 3/8 size or just get some reductions from 3/8 to 2/8?? Will be great if You can post some links, where I can get them as well.
Thanks

Question would be... Why even go from 1/4" to 3/8"??? Do you want your car to lower and rise FASTER? cause that's all you'll be doing. Is it really worth the time, effort and money to speed that up a few seconds...

Yes, I want to lower and rise car faster, 1/4 its bit too slow :/

well the problem isnt gonna be the air lines alone. you would need to upgrade your valves to 3/8 as well.

And the bag ports need to be drill-n-tapped bigger as well.

What about if I can't redrill bag ports?

Then no point tbh, also smaller line = less sway (miniscule)

I wish to lower and rise quicker :\

You rocking the 4 valve setup? Upgrading to 8 valves will speed it up also and a big plus is increased handling abilities.

actually.....
you can run 1/8 pt to 3/8 ptc for those front.

Im running on this kit:

if that will help. Sorry Im noob in this things :/

Get a New management system. those manual valves are your problem. I'm running 1/4" lines and they go up and down faster than manual

not to jack ur post but i also ordered the same for my car ksport basic but i got everything accuair for management will i have this slow lowering/raising process?

No, I'm running ksport bags with accuair elevel and it is decently fast.  Way faster than the 1/4.  It's not going to be hopping but it's fast enough for me.  I ran all DOT quick connect fittings and DOT air line.

Is anyone can make a vid of how fast susp is working?

what if I will drill another hole beside and connect them togheter??

But you still need to upgrade to a manifold/valve kit... Your biggest problem now is those two manual valves feeding all corners, instead of every corner separately from tank-valve-bag. How many ports does your tank have?
