Default Suspension rates, motion ratios, etc.

I'm looking for the following for a suspension program:

- Swaybar rate for stock 32mm & 19mm swaybars (arm length & bar length too if available)
- Swaybar rate for aftermarket 35mm & 32mm front swaybars and 21mm/25mm rear sway bar ("")
- Brake bias for our cars (Front vs. rear)
- Motion ratios for front rear spring/shock geometry
- Coeffecient of friction for common Hawk brake pads (HP+, HPS, etc)

TIA!

Carbotech Panther Plus are .54 to .56 (Coeffecient of friction), Panther XP are .58 to .60. Hawk only lists friction information for their race pads on their website.

I'd have to measure the other stuff, I have been meaning to, I just haven't had time (and I still don't have the software I need).

I receeived the info from Hawk Performance regarding their pads:

HPS: 0.30 to 0.35
HP Plus: 0.34 to 0.38

Wow, those Panthers and XP's have some bite!

I truly think that those ratings are a *LOT* like tire treadware ratings. You can really only compare them to other prodcuts from the same company.

For instance, Hawk HP Plus pads have a LOT more bite than a Porterfield R4 which is rated @ .5 I believe. And I've driven lots of carbotechs. They have bite, but not that much bite...

Sam may be correct on the "apples to oranges" rating scales. I've not driven the HP+ but I have driven cars with the HPS pads and they are different at high temps, but the initial bite (at moderate temps) is not as different from my Carbotechs as the ratings would lead you to believe. I had not seen Hawks friction rating on those pads until now...interesting.
