Back to the soft shock bladders and foam inserts. The instructions
say to glue the stock shock bladders to the pivot caps. But why whould you do this. you would have to puy new shock bladders and pivot caps every time you break a pivot cap. Which i have done twice now!
Also wouldn't the soft bladders be best for every situation because the allow more natural freedom of movement. real shocks in cars don't have shock bladders so wouldnt using the softest ones on our cars be the best benefit. since we have to use them anyway?

Well i am going with the soft bladders and staying with them. I put the shock shafts in the chuck of my dremel and hit it a little with sand paper 800# they fall easier than before but still catch a little. I don't want to remove to much material!

Wasn't my non D1 pics I posted way back earlier not clear enough for you to differentiate?
The left one is the FC steering block and the other one is the normal one. The FC steering blocks are much lighter.

then if u look at 950 wishbone rear upper right adjustable, looks more like a 705 stock arm
http://www.mytsn.com/publ/psimage.aspi?pid=7119&psid=2
i tink it's a new arm (hopup) for 705, not from 950. wat do u guys tink?

Inital D,
What diameter is the 50T rear diff gear? Does it not sit rather low into the chassis?
I drew up a 50T 3mm pitch pulley on CAD and it measured at 52mm with a 1.5mm rim edge for the belt to track against. This would only have about 2mm clearance with a 4mm chassis.

Another mod Ralph had on his 2003 Nats 705 car was the new ball diff cover or external adjustable ball diff.
Wonder signs of the new "706" to come!!!

Any closer to have a 4mm chassis from you!?!?

On a small track where the 50T rear diff pulley would be useful, I would think that the chassis will not bottom out so much as to touch the track. You need to watch out for the ride height to allow for the large 50T rear pulley.
On the Serpent starter box, the back support plate on the rear of the starter box will rub this pulley and rear belt. So you actually need to make some kind of recess on it for the rear diff pulley and belt to clear.
I believe you also need to shave off the rear backplate that supports the rear bottom pivot pins and the right rear bulkhead as well where the shock towers / shocks mount to allow the 50T rear diff pulley to rotate without binding. Hopefully I can post some pics on Friday

how do u calculate the internal ratios for 705. u have front diff pulley, mid, 2 pulley, rear 2 pulley and rear diff pulley

Front
24
24 16
18 23
46
Rear
Internal ratio for the front is as follows;
(24/16) x (24/18) = 2
Internal ratio for the rear is as follows;
46/23 = 2
For the optional 22T/47T/17T internal pulleys, the internal ratios are as follows;
Front
24
24 16
17 22
47
Rear
Internal ratio for the front;
(24/16) x (24/17) = 2.118
Internal ratio for the rear;
47/22 = 2.136
In this case, there is a very slight front overdrive which should be nothing to worry about.
It is important to make sure that the front and rear internal drive ratios are the same (or about the same) when you run the same diameter tires. If the front has a lower internal drive ratio than the rear, then you need to use different tire diameters (smaller front and rear) to make the front and rear TIRE ROLLOUT the same if you do not want any front overdrive. How much difference in front and rear tire diameter (split)? That you need to calculate also.
