Roll Centers: 1.5mm all around
Droop: FR-5.5mm, R-5.0mm
Shock Oil: 50wt all around
Shock Positions: Middle holes, front and rear
Camber: 1.5 deg all around
Castor: 4 deg
Toe: -.5 deg

Thanks for the help.
Try 1.5 or 1.0 front piviot block.....60wt shock oil and 2 hole piston.....sway bars, begin with 1.2 rear and 1.4 front.....
I think running white front and blue rear springs together will be a mistake, the gap is huge, the rear will collapse so much on longer turns but the front will be quite stiff and initially reactive but seriously lack traction, the push will be huge....
What bodyshell do you use?....I recommend Protoform Mazda 6 or Mazdaspeed 6 depending on track layout...

I'm currently running the 1.0 front pivot block. Have been running sway bars, 1.2 rear and 1.4 front. Removed the rear one but didn't really help this problem. Also running the Speed6 body. Our tracks are typically on the smaller and technical side. I can easily give the 60wt a go.

Thanks,

Russ/All- Most of our guys have moved away from a front diff all together. At IIC in Vegas our guys ran both the front and center oneways together on carpet.

I'll concur with the "no diff" sentiment. Currently using a one way for stock/13.5 and a spool with the 10.5.

Would it be the same for a small technical track ( diff or one way ) and it looks like 20lbs front 15lbs back is a good place to start. My Cyclone has never flipped but it's not very good ether. It's sweet on asphalt but I just cant seem to be able to make it work for me on the rug, I run MM4600 with a BMI chassis................. Thank you very much for the help

Well, if my info on spring rates is correct, I'm using 19 (HPI gold) up front and 17 (HPI silver) in the rear. Sway bars on both ends. Jack the Gripper compound on Sorex 28R tires. Traction and handling is excellent for stock, just as fast as any other car out there. Still trying to work the kinks out of the 10.5 setup.

Hey guys, I'm really glad to see so much discussion going on in here. It looks like there are a lot of questions regarding carpet setup (it is the season afterall). It seems like it would do a lot of good for me to take a weekend and hit up the carpet track out in AZ to try and gather some info to discuss on here. I'll try to get out there sometime in the next 3 weeks and then get back to you with findings.

*Now where does HB keep the keys to the company van?*

10.5 with sintered rotor try around a 5.2 to a 4.86
