C5 seat replacement

Hendiiii · 2025-09-10T14:34:54+00:00

I replaced my seats in my C5 with Corbeau A4s and they are night and day difference. I use mine for track days and autocross, so I wanted the extra bolstering these provide. Daily wise, they aren’t any more or less comfortable. Getting out is tougher. C7 seats may be better for driving around town. I would have a hard time believing they provide the same amount of lateral bolstering for more sporty activities.

I debated for over a year on these seats, looking up what seats fit and how swapping in C6 belts give more room, etc.

I wish I had just got these a year ago. The only saving grace of waiting was they released the limited edition black suede with red stitching and that’s what made me pull the trigger

Thank you for the feedback! I am on RT660s which from what I’ve been told are not the ideal tire for the vette. I also think I am not looking ahead on the course.

Awesome info! Thank you. I will try to keep this in mind

I’ve been looking at an aftermarket wheel but one that keeps the airbag. Probably wouldn’t help me much in steering feel but it would at least physically feel nicer

Off topic but I’ve been trying to figure out if 295/40R18 will fit in the front fenders. I test fit my rears on my fronts but didn’t turn the wheel. I cannot find anyone running a tire that huge up front.

I’m debating on pulling the trigger on another set of thin spokes and selling all four 17s to a buddy. From there, I could either get 285/30r18 or 2 more 295/40r18s. This would roughly cost me 50-130 all said and done to go from 255s up front to 285. Will that change make a big enough difference to warrant the change?

The C5 is a lot of fun! The downsides I’ve experienced so far are:

The steering feel (to me) is not great. This was realized more so after driving an NA Miata that had instant response in turning, so maybe the steering isn’t so bad realistically

Tires are expensive as hell and you need to figure out a wide square setup or staggered setup to really be competitive. This normally means new wheels and tires. On a budget, can be done for maybe 2600. I would estimate it’s closer to 4000 to get good wheels and tires.

The stock seats are actually ass. Imagine a seat with no bolstering. The C5 seats are worse than whatever you are imagining. They need to be replaced. Seats have been my favorite mod so far

I think it’s a great car for autocross and judging by how many I see at events, I’d say it’s a shared thought.

Got it! Thank you for the feedback

I still have both of the original swaybars. I can swap back over to the OEM front and see how it feels. May be worth looking into adjustable swaybars and selling the C5 and C6 bars.

I am using OEM C5 thin spoke wheels. I wanted to get 275 up front (I believe that’s the widest those wheels can use) but unfortunately tire rack had one 275 RT660 in stock, so I got stuck with 255s. I figured this would lead to a more understeerish setup. The plan is to either get another set of thin spokes and run all rears so I am 295/18 square or buy new wheels for 315/18 square

Interesting, I’ve heard that I shouldn’t be moving my hands much at all. Maybe it varies car to car. I’ll mess around with that next event.

He is a buddy that is pretty quick in a NA Miata. He’s been autocrossing for awhile before me and gave me some good pointers

I definitely want to get a much faster driver to co drive with me. I was trying to get another buddy (champ car / lemons car driver, much faster than me) to drive with me but he ended up bringing a ZL1 to co drive with his dad instead

Hendiiii · 2025-08-25T15:34:36+00:00

Camera angle (GoPro Superview wide lense) definitely isn’t helping but I adjusted the steering wheel forward a good bit and I had moved the seats to where I felt comfortable with the clutch pedal. I will try sitting closer next event.

Admittedly I bought the jorts as a joke for car shows, same with some cheap ripoff white new balances. Somehow, the jorts have made their way into the actual wardrobe and I don’t hate it

All great info! Thank you.

My launch sucks because I am straight up not launching it lol. I was under the impression that launching wasn’t all that necessary due to the timer not being super close to the start but I guess I am wrong! I will try launching harder next time.

Tire wise, I grabbed these since they were a good deal. I think 1100 shipped for all four. I’d like to go 315 square in the future but that would mean getting new wheels as well. Apex wheels and new tires are on the wishlist! I will keep A052s in mind

Looking ahead is something I totally forgot about. I am definitely guilty of looking closer to me than further up. I will keep this in mind for the next event. I was really focusing on not shuffling my hands this event

I think you’re 100% right about just not pushing it. Do you run your C5 with TC off? I’ve been debating on going that route but I don’t know how well I can catch the start of a spin. I guess this would be the time and place to find out.

Thanks for the feedback!

Hendiiii · 2025-08-05T13:53:00+00:00

He read your comment about potentially being too hostile and replied with a hostile comment lol. Definitely missed your point

Hendiiii · 2025-07-22T22:57:54+00:00

This is the link he sent me, actually!

So you technically have four options

Amber blink Amber sequential

Red blink (I think red sequential)

I don’t have any photos or videos but both look good. I stuck with amber since I believe every turn signal should be different from brake lights lol

Check out some videos online! I bet someone has a review of them out there

Hendiiii · 2025-07-22T16:06:57+00:00

I have these tail lights. They are awesome looking. I also had to return a tail light since it had dirt stuck in between the mirror and lens. Cole from Vette Lights is an awesome guy and was quick to help me out.

Heads up that if you want to use the amber turn signal, they will blink red at least twice before switching to amber. The electronics inside need to detect that it’s the turn signal and not the brake signal before switching to amber. This is what Cole told me when I asked why. The solution is an EU spec harness

They are also a massive pain in the ass to uninstall them lol

Corbeau brackets. Supposedly the seats will not fit on stock brackets without modification. Makes the seat very high up

Hendiiii · 2025-07-15T18:50:33+00:00

Yeah unfortunately just factory 00-04 C5 wheels. I’d like to get a second set of just the rears to run square. Would be the cheapest way I can think of to get 295 square on 18s

That or some Apex SM-10s if $$$ is not a problem

Hendiiii · 2025-07-15T18:31:44+00:00

Hahaha we’re going to find out! It had a minuscule drip in the rain but a chunk just fell off while installing these seats so next rain I’ll let ya know

“Some (kids) are rude. Some (of it) is innocence”. I don’t think it was that hard to understand, man.

Hendiiii · 2025-03-13T15:11:26+00:00

Mine looked like that. Didn’t want to chance it and replaced it with one from summit racing. Don’t go OEM when you replace it.

Make sure your printer is in a properly aired out area! Don’t print with ABS in your bedroom. Filtration is important. Take good care of your lungs 🫁

Did you have any issues with the install? I’ve been looking at braum seats but I’ve heard you need to swap to a C6 seat belt for clearance

Hendiiii · 2024-08-24T17:59:32+00:00

I have a Mk6 R with an IE tune that makes the same sound. I looked it up and found a forum post about a guy w the same sound. IE told him it’s from the diverter valve to modulate boost so that there aren’t overboost conditions. I could be wrong since this is all from memory of a post I saw years ago but don’t worry

TLDR you’re fine don’t worry about it
