Check with Pfafted ( forum vender) he was working on one for verts.
There will need to be plates welded to the frame of the car so the roll bar can bolt on to it.
ALso check with clubs you run with. They may have differnt rules as to what you can use .
Most tracks and clubs require a minium of SCCA Solo I tech regs PLUS pass the broom stick rule. Roll bar is 2" min above the top of your head

Best bet is to probably find a local rollcage shop and see if they'll build you something custom. (That is after doing what Tom suggested regarding double-checking the club/track rules.)

I been looking for some hoops for the C5 vert. Called Wolfe Racecraft, and they said no dice. I'm after hoops that are functional, not decorative, but I want them to look good. THinking custom is our best bet. I had not thought of Pfadt.

Odd. I saw many Vipers on track a couple weeks ago with hoops. Now, them guys actually replaced the factory hoops with heavier ones during the tech process, but they sure used 'em. The dedicated race cars had full cages, of course.

Go read the book again. the Tech section of SCCA SOLO I
One continious Hoop from side to side, with diagonal tube and at least two down tubes. ALso look at the min diameter of the tubing per cars weight.
SOme cars have factory installed Hoops. and these are strong enough for SCCA SOLO I use. The Corvette does not have this option
Viper
Boxter
911 Carrara
Audi TT
Honda S2000
Have factory install hoops that are strong enough to pass tech. Some clubs also require the Brey-Krause Hoop extender, bar that goes over the top of and accorss from one hoop to the other.
Plus the broom stick rule. When a broom stick is placed on the top of the windscreen and the top of the roll hoop, over the helmet there must be at least 2" of clearence.
Plus FIA padding with in 6" of where the driver and passanger could possibly contant the roll bar. Swing out door bars are not allowed.
I dont mean to be a PIA but I hate to see guys think they can pass a tech inspection, go to an event and get kicked out. It has happened. I have seen guys with $2000 custom roll bars get kicked out of events because the tubing used was too thin for the weight of the car.

An inspection hole at least 3/16 inch diameter, but no greater
than 1/4 inch diameter shall be drilled in a non-critical area of
the front and rear hoop as well as the one of the supplemental
braces to facilitate verification of wall thickness. Formula
Cars and Sports Racers with alternate roll structures are not
required to have inspection holes, the wall thickness will be
indicated on the back of the homologation certificate.
General Construction
A. One (1) continuous length of tubing shall be used for the
main hoop member with smooth continuous bends and no
evidence of crimping or wall failure. The radius of bends in
the roll cage hoop (measured at centerline of tubing) shall
not be less than three (3) times the diameter of the tubing.
Whenever possible, the roll cage hoop should start from the
floor of the car, and, in the case of tube frame construction,
be attached to the chassis tubes by means of gussets or
sheet metal webs with support tubes beneath the joints
to distribute the loads. It is recommended that gussets be
used
B. Welding shall conform to American Welding Society
D1.1:2002, Structural Welding Code, Steel Chapter 10,
Tubular Structures. Whenever D1.1 refers to “the Engineer”
this shall be interpreted to be the owner of the vehicle. Welds
shall be continuous around the entire tubular structure.
All welds shall be visually inspected and shall be acceptable
if the following conditions are satisfied:
1. The weld shall have no cracks.
2. Thorough fusion shall exist between weld metal and
base metal.
3. All craters shall be filled to the cross section of the
weld.
4. Undercut shall be no more than 0.01 inch deep.

permitted, but extreme care shall be used in preparation of
parts before bronze welding and in the design of the attaching
joints.
Touring Roll Hoops page GCR -106
TOURING ROLL CAGES
1. All cars registered after 1/1/03 shall conform to these roll cage
rules. Effective 1/1/08 all Touring cars shall conform to these
roll cage rules. Full width roll cages are required in all Touring
automobiles. Roll cages installed in Touring automobiles are for
driver safety and shall be contained entirely within the driver/
passenger compartment without removing any panel or accessory
not specifically authorized in these rules. The carpet/padding may
be cut around the mounting base plates.
A. The cage shall be welded to the car, and all mandatory tubes
shall use welded joint construction.
B. It shall attach to the car at no more than eight (8) points,
with the forward section of the cage attaching to the front
bulkhead or front fender wells (see GCR Section 18.2.,
Figure 1).
C. The front down tubes of the cage shall be mounted to the
floor of the vehicle.
2. For tubing sizes for front hoop, main hoop, and all required
bracing, see GCR Section 18.1.6.C. It is recommended that
gussets (flat steel, tubing, etc.) be utilized to strengthen the
joints of all required cage elements.
Main Roll Hoop:
A. Main roll hoop (behind the driver) shall extend the full width
of the driver/passenger compartment and shall be as near
the roof as possible. It shall incorporate a diagonal lateral
brace to prevent lateral distortion of the hoop (See Figure 1).
Any number of additional tubes/braces are permitted within
the structure of the cage. It is required that the horizontal
brace behind the driver’s seat (described in Section 18.2.10)
continue from the diagonal to the passenger side main hoop
upright or that a second diagonal be installed in the main
hoop.
4. Front Roll Hoops:
A. The front or side hoops shall follow the line of the front
pillars to the top of the windshield (as close to the roof as
possible) then horizontally to the rear attaching to the main
hoop. These two side hoops are to be connected together by
a tube over the top of the windshield, or
B. A front hoop following the line of the front pillars and
connected by horizontal bars to the main hoop on each side
at the top may be used, or
C. A top “halo” hoop following the roofline from the main hoop
to the windshield with forward down tubes following the line
5. Bracing:
The main roll hoop shall have two braces extending to the rear
attaching to the frame or chassis. Braces shall be attached as
near as possible to the top of the main hoop but, not more than
six (6) inches below the top and at an included angle of at least
thirty (30) degrees. On cars where the rear window/bulkhead
prohibits the installation of rear braces (e.g., Honda del Sol), the
main hoop shall be attached to the body by plates welded to the
cage and bolted to the stock shoulder harness mounting points.
This installation design must also incorporate a diagonal bar
connecting the top of the main hoop to the lower front passenger
side mounting point (“Petty Bar”).
A. Rear hoop braces may pass through the factory bulkhead
or panel separating the driver/passenger compartment from
the trunk/cargo area/, fuel tank/fuel cell area, provided the
bulkhead is sealed around said cage braces. Metal tape may
be used to seal the openings between the bulkhead and the
tubes.
6. Side Protection:
Two side protection tubes (door bars) are mandatory on each
side of the car. NASCAR-style side protection is required on the
driver’s side and is optional on the passenger side. The driver’s
window safety net may be mounted to this side protection and
the top cage tube. NASCAR-style side protection tubes shall
extend into the door. The door window glass, window operating
mechanism, inner door trim panel, armrest, map pockets, and
inside door latch/lock operating mechanism may be removed
only if it interfered with the installation of NASCAR-style side
protection tubes. The inner door structural panel may be modified,
but not removed to facilitate this type of side protection. The
stock side impact beam and the outside door latch/lock operating
mechanism shall not be removed or modified.
D. The mounting plate may be multi-angled but must not exceed
these dimensions in a flat plane.
E. Any number of tubes may attach to the plate or each other.
8. The driver’s seat shall be firmly mounted to the structure of the
car. In cars where the seat is upright the back of the seat shall
be firmly attached to the main roll hoop, or it’s cross bracing, so
as to provide aft and lateral support. Seats homologated to and
mounted in accordance with FIA standard 8855-1999 or higher
need not have the seat back attached to the roll structure. The
homologation labels must be visible. Seat supports shall be of
the type listed on FIA technical list No.12 (lateral, bottom, etc).
A. Each mounting plate shall be at least .080 thick.
B. Each mounting plate shall not be greater than 100 square
inches and shall be no greater than twelve (12) inches or less
than two (2) inches on a side.
C. Whenever possible, mounting plates shall extend onto a
vertical section of the structure (such as a rocker box).
