Default C4 seats in a C3??

Anyone ever put C4 seats in a C3? I've seen the C5 and C6 seats in a C3 and they don't look bad. However, there was a particular seat of the C4's that I liked and was wondering if anyone has done the swap. For those that have C4, C5, and C6 seats, do the seats offer a more comfortable ride?

I've seen the C4 seats in a C3 and thought they looked great. One was in Eureka Springs this summer.
I, like many, have the C5 seats in mine and find them 100% better then the originals. I had the '79-'82 seats for awhile and the C5 are a lot better, as far as comfort, to me. The C5 seats are very light and look right at home as well as being a pretty simple install.

I've installed C4 seats (non-power) in my 1980. The frame rails from the C3 seats were used, and a tab was welded on each to mount the front of the seats. The backs bolted right in. Very easy and clean. A lot more comfortable and way more side support.

The pic isn't so hot, but you get the idea...

Very common. An archive search should turn up lots of threads.

Do you have any pics by any chance? I would love to see them.

The seats look like the fit right at home in there. I think the seats look great in that pic. Is that an early C4 seat? Is the seat adjustable? (I've never rode in a C4) I think the C3 seats for '73 look great, but it bothers me that you cant adjust them. They also seem to bend the frames pretty easy causing them to lean making them uncomfortable. Also, like you mention, they offer no side support which sucks when you go in to a corner pretty hard.

Will do... I thought of that after I made the post.

I couldn't find any pictures of the C4 seats in the C3. The ones in this thread are the early standard seats. There are two other styles from the C4's as well. The ones I saw were the later C4 like the ones on the right in this link. http://www.mamotorworks.com/corvette-1-52-3972.html

I just found two pages of threads. Run this exact search, including quotation marks, in the archives, selecting all C3 forums: "c4 seat*". I think everything you need should be there. (Just in case you aren't familiar with archives searches, my "Search!" sticky in C3 Tech has instructions.)

The seats in the picture are standard non-power seats in graphite from a 1988 vette.

I have sat in a C3 that had C4 seats and you end up sitting higher than before. Im 6' and i was almost hitting the top... one good bump and i would have. You have to consider that, but as to comfort, they are a million miles ahead of C3 seats.

Here is another question for you seat guys. Which option is more expensive? new foam and covers for a C3 seats or buying C4 seats to put in? that will be the deciding factor for me...

From the lowest part of the seat cushion to the bottom of the T-Bar center (eye-balling over, measuring straight up) I have about 33". Not sure how that compares to the original seats. Can you check yours? That's the C5 seats, don't know about the C4 height.

Here is another question for you seat guys. Which option is more expensive? new foam and covers for a C3 seats or buying C4 seats to put in? that will be the deciding factor for me...
You can get the standard C5 seats for around $500. and, of course they go over a grand for the sport seats. I bought mine on the forum for $500. shipped (I believe) with tracks and sold the tracks for $150. Haven't priced the redo on the C3 seats, but they can get way up there also. Or you can redo them yourselves for, what, $350. - $400.
All those prices vary greatly depending on condition, shipping, leather or fake leather, etc. of course. I've seen standard C5 seats well under $500. but they are in rough shape.
C4 seats are all over the place, I'm not up on those. But I do have a pair I'll never use.

I have a 91 C4 with standard seats (both power). They are not the most comfortable seats. IN MY OPINION, my C3 seats are no more or less comfortable than the seats in my C4. Both have been recovered with new leather and both have the original foam.

If I were changing seats in the 72 I would not install my 91 seats.

I cannot speak to the newer C4 seats. Check in the C4 section for the guys with the newest C4s (94-95-96). There are a few of them with C3s.

Out of the guys here that do have the C4 seats. Are either of them saddle or tan and would you like to get rid of them?

Do you know who the seats where mounted? I saw a car on ebay a couple years back that had the C4 seats that had the perferated leather and they looked shorter than the stock C3 seats for some reason. I am kinda short at 5'8. I don't think this would be a problem for me. So, hopefully they'll be about the same..

I think they look good. Do the seats sit any taller than the stock C3 seats. I might be PMing you later on down the road (if you don't mind). I would def. like to see how you mounted them.

Those seats are phenomenal. I would also say that yours are one of the nicest as well. I think the C5 seats look a little plain without some color and I am liking the red on you seats.

Do you have any pics or info as to how you used the C3 rails? It looks as if the C4 seats sit at a slight angle.
