Tweak
Hi guys, ive been following this thread and most of you have said your car has tweaked out fine. Im having a few probs with tweak on my Pro4 tho, if I take the body posts off and rest the car upside down on a flat surface, 3 of my shock towers will touch the glass, the other one wont 
I have tried undoing the topdeck and screwing it back up again on my glass, and I have treid to fiddle around with the diffcase screws on the bottom of the chassis but I still cant get anywhere with it. The main chassis and updeck on their own seem perfectly flat its when its all screwed up tight that I have the problem.
It is very noticable too, when I accelerate the car pulls to the left, when i lift of the throttle it pulls to the right.
Could it perhaps be the diffcases or even mis aligned holes in the chassis?
I am no expert at this and any advice as to un-tweaking would be a great help.
Thanks.

Try tightening the screws down with the wheels off whilst applying pressure to the car to keep it flat.
I have done this method, and although it is pretty tricky it seems to solve the problem.
My Pro 4 is on rails around my local indoor carpet track, only broken a few bits so far...however I did break a C-Hub and steering block in a rather tame crash

Is it fine without the top deck attached?
It could be that the holes are slightly out on the top deck, do they all line up when you just place it on the top?
Also, you could try turning the top deck upside down and using countersunk washers, I know a few people have done that to solve the tweak problem...including Hara.

HPI do a ball diff set which includes everything you need to build up a ball diff for the front. You also get spare outdrives for the main shaft and a spare plastic pinion bevel gear.

If anyone has a part no. please share it. If not, I'll start the search with the Pro4 manual and other included sheets.
