Front and rear weight remains constant, left and right remains constant, if the right side is light it will always be but in terms of handling at the first order you can always compensate a lot of it with the shock preloads

Re your rear leaking shocks, if it leaks from the top the membrane is shot.

Ok , sorry for all the noob question , i apologise .

I didn't know what the hell I was doing Now I will attack the problem again like you suggested ( shocks detached ) , move my weights around then de-tweak on my Hudy board... If anyone has any suggestions or tips on de-tweaking with scales I would love to know... Thanks...
Charles, bring your scales to the track. I will tell you how to do.

Thanks,

Honestly, I never use scales to detweak my car. I weigh each individual electronic component I put in the car though, and add weight accordingly to balance those things out.

But to actually un tweak the suspension, I take the shocks off and loosen all the bulkhead screws and upper deck screws to let eveyrthing relax. Then I plop my car on my new PPD Billet Tweak plate as it bolts the chassis to a flat peice of aluminum. After the car is bolted down I tighten all the screws back up again. You can accomplish the same thing by pressing down on the chassis when the upper deck screws are loose, but I think the PPD billet plate is a very easy, and effective way to untweak the chassis (as long as there are no bent parts).

Then I will measure the shocks, and make sure they are the same left to right. Then I will measure rebound and make sure they are the same left to right. Then I put the shocks aside and make sure the arms have the same amount of downtravel left to right. At that point I'klll put the shocks back on, and put everything in my car except the body to set ride height and do some final tweaks on the preload to make sure everything sits right. I always use the tip on an xacto knife to lift up the chassis from the bottom along the centerline to make sure the left and right tires lift up at the same time. Then I do the front the same way.

You will have a leaky shock with inconsistent rebound.

What does it do by standing the shocks or laying them down ?
Ive been told that standing them will decrease weight transfer and make the car more responsive . Is it the right thing?
Ive notissed that at the IFMAR 2008 everybody is laying there shocks on the rear and standing them in the front ? Why ?
thanks

Could somebody tell me if i want to have a full option Cyclone S, so which is the better and easier way: to purchase a Cyclone TC then changed it with a tub lower deck, or just buy a genuine Cyclone S then full modified it?
And somebody could tell me if tub really weighs much more then carbon lower deck?

In the case our org. has created already a new race class, with 1600G and 3100KV(if you prefer BL) then with black sport tuned if BR, so i want understand if Cyclone S with TC parts is worthy or full options Ta05 is better.

Best regards

The tub is a lot heavier than a CF deck, dont remember how much by. Try searching the cyclone s thread.

OK, maybe i don't need to add lead on the tub, thanks.

Could you then somebody tell me if the carbon top deck really match on the tub?
In the case on the HB site, the option parts list is included.

Best regards

Pretty much all the parts match the tub chassis so you'll be good...

If you look though the Cyclone S thread, they probably got all the answers you're looking for
