Hey guys - I'm new to the light weight bucket seat in my GT4. I had 18 ways before.

I was wondering if a certain feel is normal. I'll try my best to describe it. It feels like over sharp bumps in the car the cushioning in the seat compresses all the way touching the shell.

The way it feels is an abrupt bump / knock when going over sharp bumps.

Does this make sense? Almost like a clunk or something. I've got warranty on the car, I just wondered if it was something I needed to have checked out.

Mine does not feel as though the cushion compresses. It can be described as "stiffly sprung" and not a "soft" riding car - but I don't have a sense of feeling the hard seat bottom, rather than the cushion - over bumps.

If that were my car and I was experiencing what you describe, I'd want my tech to drive it and feel what I'm feeling. I'd also want to drive another GT4 with LWB (if at all possible) to see if my car felt different from another.
Not sure where you are located but if you are in my area you're welcome to drive mine once it comes out of hibernation.

I'm in the bay area california. Yeah I would like to drive another one over regular roads to test it out and see.

Perhaps I'll check the seat bolts to see if they are tight.

Seat bolts is a good thought. They used to come a bit loose in my Z06 every so often (it was race seats I put in - not OEM).
At the very least - if you can't drive another one - if you have a trusted tech with a good "butt-o-meter" they should be able to tell if something is off.
And in that area of the country I'd think there are other GT4's around - maybe someone will offer a test drive or maybe you'd find one used at the dealer that they'd let you take for a short spin.

Good luck!

Thanks for the help. Still hoping someone will chime in.

Check the bolts...

Bolts were / are super tight. I still feel like it's the cushion or something hitting against the shell. With visual inspection the seat seems tip top.

I'm guessing a little flex / padding compression on hard road bumps is normal. I'm just paranoid because a) never had those seats and b) i'm the third owner.

You may want to pull the seat pads and check ?
Its an easy task... Its just velcroed in
I am local if you want to swing by after the monsoons depart

I might take you up on that! I still need to install my covers!

So your seats don't ever feel like that?

Maybe I'm too much of a lard ***. Lol.

Do you have seat angle adjusters installed? If so they can make the seat drop down too far in the rear and clunk against the seat frames. Try raising the seat up to mid-way through the travel and see if it still happens.

bk_911

I never installed one. How do I tell if the car has it? who makes the adjuster so I can see what it looks like?

I suggest you ditch those LWBs quickly to, say...me!

BTW: where did you get them?

my 991 buckets in all cars i have them in do not bottom at all - you are heavier than me but not by that much - something is wrong with your seat/cushion... maybe a harness belt or loop stuck down there??

All bolts? Not just the floor? ...I can promise you, I'm the heaviest GT4 driver there is.. and they do not knock.
