Randy and Andy,
You guys crack me up. Our cars aren't traveling at speeds close to 2 MPH. Well, at least mine isn't.....
Look here:
Sports Car/Formula Car - 8770 Series canister option
Here is some text from that link:
Tuning Adjustments:
Low-speed compression:
30 clicks of adjustment control the low speed nose area of the curve. This adjuster is used to tune role stiffness, turn-in, and understeer.
High-speed compression:
64 clicks of adjustment control the high-speed blow-off area of the curve and adjusts gross threshold of compression damping. This adjuster is used to tune bumps and curbs, and to gain a general direction in damping levels.
Funny. Penske doesn't mention high versus low speed corners. I wonder why that is?
