sakura fdr
hi guys.>im from malaysia...currently im running sakuras new x1>and i need some help here, i am tryin to set my car up for my 17.5t stock
the issues that i am facing is the fdr for my local track...its a high speed track..and many racers using xray and tamiya are able to achieve fdr 3.1
however as for my car i am only able to go as klowest as 3.8
due to the limited space for the size of my pinion. i have tried other options like changin the centre pulley to acheive smaller internal ratio..but this would put alot of tension on my belts....
i need help on this....
i cant keep up with other racers even with good racing line due to the difference in the fdr....
sos......desperate for help.....
