Yep. You can run diffs and spools both front and rear.

Is there an upgrade for the cvd assembly or bone?
I am now running the spool and I keep going thru cvd assembly

Top Photon driveshafts fit.... would be best to mill out the spool to use the plastic blades... which is what i will do next time i need to replace the aluminium CVD's
Oh, and just want to say how much i STILL love this car... bought it new WAY back in the day and still love it
just ordered some new hubs and rod ends to freshen it up a bit...

Ive been wondering for a while if the car handles better these days (relative to belt drive cars) now that that minimum weights are lower?
Although i think being competitive without a spool up front would be tough. As a spool will just smash up the bevel gears

I have been running the spool in it with 17.5 and its fine. Will be running it with 10.5 shortly... The bevel gears are fine if they are meshed correctly and you stay off the barriers. And yes, its great with the new weight... I have heard that the cyclone 's' arms work great on the Pro4 to add overall traction... and comments?

To tell you the truth i havent run tourer in a while but i was rebuilding my pro 4 not long ago.
Unfortunately for me keeping off the barriers and such isnt exactly a viable option, but i was thinking about putting a slipper spool in the front.
Yeah the cyclone s had the high traction arms included in the kit, which were a softer material. Its a cyclone part, 31420 should be the part number you want.
Just make sure if you get some you label them as they look identical to the standard arms.

I always liked a oneway more than a spool..but they both have their place and track..the best "thing" for traction for a pro4 is the 2mm chassis, then tune with the different top decks..
..Hara ran a 2mm chassis on his pro4 and used the different top decks to change the traction handling. Stock for a pro4 is 2.5.

Interesting... Was thinking about a thinner deck.... having some trouble keeping the speed through the corners.
09-19-2010, 11:07 PM
Why would a thinner chassis lose speed in the corners? I don't think that you would lose speed, remember you can make the chassis stiffer by changing the top decks, they did make a 3mm top deck.
09-19-2010, 11:44 PM
no no... iam losing speed with std chassis... so i want to try the 2.0 chassis to see if it helps
09-20-2010, 12:01 AM
Might try and mill the standard chassis a little? Anyone tried this with this or other chassis?
