It appears finding Z06 with competition seats are extremely hard to find, so for those who track with GT2 seats, do you slide around too much? Mainly the knees I think would be main concern. I switched from 18 way seats in a Porsche GT4 to Buckets Seats, they kept you in place, no concerns about moving around.

Regardless of seat, if you install a harness bar and run 5 or 6 point harnesses tightened the way they should be, you will not move at all as you will be sucked down tight in the seat. It also gives you about an additional 1" of head/helmet clearance. With the Paragon harness bar installed, 10 people could look inside my car and not even know it was there. The lap belt bracket may reduce seat rear travel about an inch which could be important if you are tall. I am 6', 180# and no issues with leg room or helmet clearance. On most 5 or 6-point harnesses, you can run the sub strap between the seat back and the seat cushion so you are sitting on it. For that setup you do not want the harness buckle on the sub strap. A great harness, though expensive is the TeamTech Jet Pilot harness that has the sub strap attached to the lap belt, like a rock climbing harness.

My C8Z has GT2 seats, and the harness bar was an easy decision as I run a number of events that require 5 or 6-point harnesses. I use them at all my speed events. I retired from wheel to wheel racing 8 years ago, but still enjoy speed events and obviously am happy being "locked down" in the seat.

Wow, what? Harness bar I got, can you send link to this 6pt harness setup? Images? Does this setup damage the seat? In my Porsche world, the bucket seats had hole towards front to slide the harness up, so it was beyond comfortable, couldn’t move in inch it was so tight.

I’m also 6/180lbs. Lol

Pretty sure the seats in the cars at Ron Fellows Corvette School are the GT2s. I'm certain they are not the competition seats. They kept me in place. 6'3" 190 pounds.

I got mine late August and was able to get 7 track days on it. I was all over the place with the GT2 seats so over the winter I installed a Peitz harness bar and harnesses. Track opens 4/11 and I'm assuming this will solve the problem.

Aku700

I assume this is a 4 pt harness option? What price does this setup cost, bar, harness and brackets for the seat?

You weren't trying hard enough. The car I drove at RF had GT2s (and iron brakes), I picked it because I wanted the same basic specs as what my car has. Even with the seat belt cinched, I found myself having to brace myself in hard cornering with the GT2s. It wasn't horrible, but it's definitely something to be aware of. If you're going to do a lot of track use, I'd either hold out for the competition seats, add a harness bar and at least a 4-point harness, or maybe even do both. The GT2 seats actually have pretty good support, the issue is that the car has such incredible limits that anything short of a full on race seat or harness setup isn't going to hold you securely if you're really pushing it.

Aku700

well said, that does appear to be the case!!

GM doesn't make anything akin to the Porsche bucket. The comp seats are 99% the same as the GT2 seats in the torso, but have higher leg bolsters.

The answer to this question depends on your size, body composition, and skill level on track. Also, using the OEM seatbelt cinch feature does 90% of what harness and a harness bar do. I would only do harnesses if switching to an aftermarket seat my $0.02.

I have been tracking the car with the standard seats (GT2 and standard have the exact same frame/foam dimensions, GT2 just have a cooler looking upper half). I am 6'4" 230 lbs and while manageable, I need something more at the pace I drive. I cannot fit in the comp seats as the leg supports dig into my hip bones.

If I continue purusing tracking this car I will be doing a proper race seat w/ harness bar etc.

OH THREE Z

I’ve driven and rode shotgun in P cars with buckets. I can say with 99.9% certainty 98% of corvette owners would hate them. 90% likely couldn’t get out of them. A totally different demographic with different expectations for and of the car.

I believe the corvette team knows this and thus the reason why the comps are the most aggressive offering.

Hell. A GT car with sofa or 18 ways are looked at (by many) as a poor spec… I feel a corvette with a bucket-like seat would be viewed in the same manner by the corvette crowd

Aku700

yea, I’m starting to notice this as literally like 10-20 cars in the country for sale have the Comp Seats, it’s crazy.

and FYI, the P crowd is changing, believe it or not, if found that most 992 GT3 have sofas spec now, not sure why, but I’d say big shift, maybe P car drivers getting older, not tracking as much, dunno.

minuteman71

Yes 4 pt Schroth harnesses. A bunch of the 4 pts I looked at had 2" shoulder straps which isn't going to work well with a hans device. I got the Peitz harness bar from Cicio and which doesn't include the mounts for the lap belts so those are additional.

minuteman71

Coming out of a 718 GT4 with full buckets it's all about body type. I am narrow of hip and relatively thin and as my primary purpose for these toys for me is track they were great. I bought aftermarket inserts with memory foam which help the comfort index. If my harness setup proves inadequate I have some aftermarket seats I'm considering but challenge #1 is getting the airbag light to go off and not read as a fault from the ECU. Without that my car wouldn't pass state inspection.

Aku700

they supposed to be 3”? Is that why? Because I do have helmet and Hans, but not sure of the shoulder strap size

and did you find these additional parts? You’d figure one place would sell all parts required

RapidC84B

Huh? Shoulder belts for HNRs are supposed to be 2". I prefer the Schroth 2" 6-pts because the 2" hip belt fits better.

EvanZR1

FYI, for HANS, while at Ron Fellows they used a shoulder harness system with the 3-point belt. I think it was the Simpson Hybrid Sport.

minuteman71

You may be correct and some of the harnesses use 3" straps and I got 2" straps I'll check tomorrow when it comes down from the lift. The harnesses I bought are described as follows:Schroth Porsche GT3 / GT4 4 Point ASM Harness

Also from Cicio

Aku700

question is, how do you get 6pt harness on a C8 with OEM seats? I don’t want to install aftermarket, it creates fault codes, etc, and you lose 1 airbag, which could be pretty important

RapidC84B

Yes I own one... use it for instructing. Nice piece.

HNRs require 2" shoulder belts.

There are a lot of options.. you need a harness bar and then lap belt mounts. With a 6 point you can sit on the sub straps.

Aku700

Do you know anyone that makes/sells the 6pt harness option for the C8? The OEM seats have no center hole access to pull through the sub strap?
