So I started this a few years ago and other stuff got in the way. Now I am back on this.

For now I intend to keep all the OE glass. Since the glass is bolted to the car through the glued OE clips, do I need to add the metal clips and straps on both the front and rear, inside and out? Seems like it but wanted to double check.

The clips are required. I used nutserts to hold them on.

Thanks! Do I need the front and rear interior straps also?

Page 85 of the May GCR Update:

9.3.54. WINDSHIELDS/WINDSHIELD CLIPS/REAR WINDOW STRAPS

Windshield safety clips and rear window safety straps are required on all closed cars, except on American Sedan, B-Spec, Spec Miata, Touring, Improved Touring, and Super Touring, where they are optional. Alternatively, no clips or straps are required if polycarbonate windshields and rear windows are securely bolted to
the frame.

3 clips (3 inch x 1 inch x 1/8 inch) shall be bolted or riveted to the body at the top of the windshield.

2 clips (3 inch x 1 inch x 1/8 inch) shall be bolted or riveted to the cowl and extend over the bottom edge of
the windshield. Clips shall be spaced a minimum of 12 inches apart.

It is recommended that 3 – 1 inch wide strips of steel or aluminum be installed behind the windshield to support it from collapsing inwards if it becomes damaged. The rear window shall be secured with 2 metal straps (1 inch wide x 1/8 inch thick) bolted or riveted to the body at the top and bottom of the rear window.

Thanks. The rear straps are part of the recommendation for the front? It does not state if the rear straps are to be on the inside or the outside.

Hold on a second.

We have to add straps or clips to the OEM windows?

Are you guys sure about that?

Chris:

I think the front straps are optional, but the rears are required. Usually attached on the outside.

The way it is written we need front clips, and rear straps, even with glass. The front interior straps are recommended.

From the Prod Rules

Quote:
Glass - Windshield and Door
A. Open cars may remove the windshield glass, door window glass, quarter window glass,
rear glass, vent glass, as well as its frames/channels and all mounting brackets. Window
winding mechanisms can be removed. If removed, a replacement windshield must be
installed. The replacement windshield must be fitted within the vertical planes of the
front most and rear most elements of the stock windshield and frame. The replacement
windshield must not exceed the height or width of the stock windshield and frame. Any
portion of the windshield that is in the driver’s line of sight, must be constructed of a clear
material. No part of the replacement windshield can be constructed of glass. If the stock
windshield frames/channels are retained, a high front roll cage hoop must be utilized, and
the stock windshield can be retained or replaced. If replaced, the replacement windshield
must be of a polycarbonate material with a minimum thickness of 6mm, be identical in size
and curvature to the stock glass windshield, and have a minimum of three vertical inner
supports to prevent the windshield from collapsing inward. Inner windshield supports
must be a minimum of 0.75” by .125” straps of aluminum.
The inner supports must be
mounted a minimum of eight inches apart. The rear window can be removed, as well as
its frames/channels and mounting brackets.
B. Closed cars can retain or replace the stock glass windshield. The replacement windshield
must be constructed of a polycarbonate material with a minimum thickness of 6mm,
and must be identical in size and curvature to the stock glass windshield. Replacement
windshields must have a minimum of three inner supports to prevent the windshield from
collapsing inward. Inner windshield supports must be a minimum of 0.75” by .125” straps
of aluminum.
The inner supports must be mounted a minimum of eight inches apart.
