I used this to fill in the missing space that has developed during years of hard driving, the easy part was side supports and back support,
thats what i used but cut in half to do side leg support, its from boxes with expensive lamps for warehouse, 2 in each box. but i am sure you can find thats stuff used for shipping other things too.

i got plenty of thats stuff going to do pass seat soon. its a great upgrade if you willing to spend
1 hr / seat
seat does sit higher and feels much more supportive and comfortable and its soft since you placing that stuff under your original worn out pads.:biggthump
thats foam stuff is good even for sound insulation like subwoofer installs
g20 armrest and altima headrest does wonders too

I also got new tires bridgestones fuzion hri 195/60/14 at my local tire plus for only 225 with tax, they did charge me $12 tire disposal fee.

now i can do some hard cornering!

Huh? You lost me mang!

do not ever try to stop in the rain with those pepboys special tires. I had that same brand on my NX for about 6 months, worst tires I have ever had on my car.

I added more foam under original seat foam
By the way tires work great so far i was driving in heavy rain yesterday very good cornering grip

My greatest seat upgrade when I had an NX was SE-R seats :)

i took the back of the pass seat and put it where my driver seat was....big differnce bcuz the seat was used alot less
