Guo...Your car looks great.....almost the same as mine!!!!!!!!!!
I cant see in your photos but have you done the top deck mod?(Drill out the top deck were the screws go thru to hold the front/rear bulkheads) I found that was the biggest inprovement to stop tweak.
Also do NOT make the same mistake as I did...Used a carbon shaft for Mod...It twisted the shaft 180 degrees!!!!

Spur and Pinion in 48 Dp
I would like to knw which SPUR and PINIONS in 48Dp will fit on the Pro4. And pinions will have to be short, so no motoplate will be needed.
Please give me some brand names ? thx !
I also made an excel-sheet with gearratio's in 64 and 48 dp for the Pro4 :

my car is running sweet at the moment, drivetrain is super free and handling is dialed, however I am having a problem whenever turning right on or off power i get a binding noise, similar to that of a stripped bevel gear....
ive pulled the car apart a dozen times now trying to find the source but everything looks perfect, the noise is only when turning right, left is no problem, any ideas?

Check your CVDs? There have been a few people at our track that have overtightened the set screw in the CVDs causing the pin to bend. This causes the CVD to bind at certain points ....

I've had this problem everytime i race. One was caused do to bevel stripping. I never realized it could be the cvd binding.

I dont own a dremel. Is it possible to drill with normal drill?
