Absolutely! The harnesses need to be correctly installed, but there are no rules against harness bars except maybe in stock classes.

Hi Antohny, I do Tech for our Time Trials (and instruct in a 92 Corvette).

Kevin's correct that the bars (properly installed) will pass tech.

However, the setup in the picture (and for any C4 seat) is extremely dangerous. This is because C4 seats are too wide where the belts pass around the seat.

In a frontal impact, the belts will be wide enough to slip off your shoulders. It's possible that you could go right thru the belts and into the steering wheel.
There's been a lot of discussion on this in the Corvette forums.

Kevin may want chime in here or Kevin Weiss if he's still Chief of Solo Tech as I'm not real familiar with the Solo rules.

Wanting to put in a 5 point is a great idea and makes the car easier to drive but best thing to do would be to put in a race seat with pass through holes for the belts depending on what it does to your car's classfication. And switching from the stock seat to the race seat in a C4 is easy , about 15 minutes.

Feel free to contact me if you have some specific Corvette questions.

Hopefully we'll see you at the Annual Tech Day at Summit Racing on March 30th.
Bill

from the SCCA Solo rule book 13.2j

J. Driver restraints as outlined in Section 3.3.1 are allowed. Seats may
not be cut to allow for the installation of alternate seat belts or harnesses.
Passive restraint systems may not be removed.
Removeable
seat headrests may be repositioned using the original mounting
hardware only if the OE components permit it with no modifications.
This includes removing a headrest and reinstalling it backwards.
A
horizontal “harness bar” may be used as part of the installation hardware
for allowed driver restraints provided it has no more than 2
attachment points to the chassis and is bolted at those locations. A
C-type harness bar may also be used. It may have 4 bolted attachment
points to the chassis (2 primary and 2 supporting connections

to resist rotation). Truss-type harness bars are not allowed.

And Bill is correct about shoulder harness & stock seat. You can install just the 3" lap belt to lock your but in the seat.Choose what class you want to run in this year and read the rulebook and prep accordingly.

Thanks, Pat. I don't have the Solo rules on my computer.

One note, I'm not sure in what year Corvette it started but the C4's have a "Cinch" button on the seat belt housing. You can pull the seatbelt as tight as you want it, hit that button and it locks the belt (nice feature).

The Cinch button does not lock the shoulder belt though.

Thank all you for the responses.

I am having trouble figuring out which racing seats will work on my car, since it is a pretty tight fit. And noticed the only company that makes a seat bracket specifically for my car is Corbeau. My model does have the clinch button, which really does help. I still find myself having to adjust while coming out of some turns.

IIRC, the A4 will fit but check with them first.
