Here is some information I have found.
Installed height
30.6mm / 30.5-31mm - 1.2007874"
ID - 23mm - 0.905511811"
OD - 30mm - 1.18110236"
Seat pressure that I have read tossed around for seat pressure, between 90 and 100lb.
The only stumbling block right now is spring rate, what rate do we need.
I have found some bee hives that will work but it will require some removal of material...about .2"(7mm) from the spring seat, not including a washer to prevent the spring machining into the head.
My only concern is they had a video of these springs in action, and they where bouncing at 6500rpm, cam profile plays a big part in this; with ours being so very mild... :?:
:!: Note: I am just researching, if you choose to buy these and use them…that’s your choice. I am, in no way, recommending them, or saying they will work.
