I get periodic requests asking if there is any way to lower the stock C5 or C6 seat. I took a bottom frame and placed it above our ultra-low seat bracket. It appears that if you don't mind losing the sliders you could bolt the seat directly to them and gain at least 1" of headroom. I compared the height to the C6 manual sliders I have and the frame was sitting 1.5" lower.

On the bottom frame I have the plastic part of the mechanism that adjusts the seat back angle protrudes 1/2" down below the bottom of the frame.



I added a 1/2" of shims between the frame and our bracket.




You would need to confirm your legroom would be adequate if the seat is positioned in front of the rear floor studs so you can still tighten the nuts down. It would be near impossible to get to them if the seat was above them.




This has never been done yet and I have no input as to what else may be impacted by doing this. This is simply to show that mechanically it is possible, since some people appear desperate for more headroom but want to keep the stock seats. The bracket below is the one I used. I would recommend using grade 8 button head cap screws coming up from the bottom with nuts on the top, since the bracket is already on the carpet in the rear.

I know this post is a bit old, but did anyone ever end up trying this?

I'm desperate to gain some headroom in my 02 Z06. Eventually I hope to put in an aftermarket seat. But for now, anything that can lower the factory seat and make me less miserable in a helmet would be worth doing.

Thanks,

Looking at this a little more closely, I wonder if it'd work ok to cut a notch in the left rail to accommodate the seat recline mechanism, rather than using those half inch spacers. That'd get the seat right down onto the rail. It might compromise strength slightly, but it wouldn't be hard to weld a reinforcement in there. Also, the left side doesn't carry the load of any seatbelt mounting points (except the sub bar if used) so it wouldn't really compromise safety. That seems like it might get the full 1.5" drop, or more.

Not to my knowledge, and I haven't been encouraging anyone to. I had people asking if it were possible and simply showed what I found out. I won't be modifying any parts to do this.

Thanks for the response. That's helpful to know.
I'm definitely going to give this a try. I'm not sure yet if I'll try using the spacers as in the photos you posted, or if I'll try to cut a notch for the recliner and weld in reinforcements. Either way, I'll let folks know how it goes. For those of us whose heads touch the ceiling, this is a pretty significant safety modification.

Your best bet is to try and contact LymanSS by PM or e-mail for an update from him. He hasn't had any activity on the forum for a few months.
