Most races have a weight limit rule of 1,525 grams, since pro 4 out the box is lighter, you add weight on a balanced weight distribution.

Mach10_shooter: A301 for the steering links and A302 for the upper links. (They both come 8 pcs to a set)

Re: The center stiffener post is purely optional.
Re: the gear brace, if you purchased your kit in the USA and you have the older version with no brace included, give US customer service a call.
Re: The gear shimming… for the front one-way start with 0.3mm on the gear side and 0.2mm on the longer side. The front input shaft requires no shims. For the rear, the input shaft should be per the manual. The diff should get 0.2mm on the gear side and 0.3mm on the longer side. Note, if you experience any breakage of the front gears, add more shims to reduce the gear backlash. No backlash is okay and will yield more durability (with a slight efficiency cost).
Re: your car pictures, it looks as though your battery strap is a bit loose. See the attached .jpg for possible cause. The manual is incorrect for step 41.
Re: Complete spring set is HPI Part # 75175 (7 pairs), you’ll need 2 if you want 4 of each spring.

dontfeelcold: A spool is included with USA 2005 spec (I believe will be called Hara Edition)

Pro4: The USA spec kits use MIP CVD’s. The Asian market (+Austrailia) kits use universals.

cpatel529: Any gear shims needed come with the kit as standard parts.

rc-zombies: The new shocks should be about 56.5 center to center. Set longer if running lots of droop.

when changing the roll centre on the car, is it necessary to change the height of the camber links as well?

Thanks in advance!

Had a great race last Saturday. Setup turned out to work great. I was a little worried about the driving difference of the rubber tires since I was so use to foams. Turned out I could drive the car just as hard into the corner with no worries of traction rolling. Car was SOLID!!!

take care
john

Evicerator: Feel free to gear taller by 1 tooth. If in doubt, don't hesitate to consult your manual

racer: When you lower the inner camber link, you will raise the static roll center. When you lower the suspension pivot block, you will lower the static roll center. In transition it is a much different picture. Changing one or the other should have a bigger feel difference than doing both at once.

Thanks for the explanation, really appreciate it. i guess my actually question would be.

since i have changed over to a 3mm lower chassis. will the setting be altered?
i would like to keep the stock settings. how would i achieve this?

Thanks in advance!

racer: For a 3mm chassis I would start close to this setup(Andy Moore, Cleveland '05) for the pivot block and camber ball heights.
