Hi bro, i also own OTA, playing at SKDM last sunday.
Would like to ask you about the pulley.
Your rear pulley using 36T/21T, will the 21T small pulley hit the belt cover and chassis?
Coz i try installing the 19T pulley oridi like hitting the belt cover and chassis.

I did not encounter such problem on mine......its should fit just rite.n im not doing any modification on e belt cover. Maybe we can meet @ SKDM after CNY,i can a look @ urs.

Oo.. ok. Thanks. How about the belts? Did you replace any belts, with short ones or you just adjust the diff. spacer?

I didn't change any belts but only mod my cyclone tensioner to tension my front belt,cause im using 17T instead of 18T.

Ay? But my front i using 39T/16T , i only adjust the spacer, no need tension ley.
:confused:

My setup is
Front: 39T/16T
Centre: 22T/14T
Rear: 39T/18T
Cs ratio: 1.77

Aiyahh.....never tot of tat....:blush:

For the rear, if using the 39T diff.pulley with the stock belt , the small pulley cannot be more than 18T, otherwise even if you adjust the spacer , the belt will still be very tight.

I encountered e same problem wit my front belt when i use 39/18T,tat is y i decided to use 17T instead of 18T. N I need some belt slack for better transition btw on to off throttle

Actually there is one more tab, which is the last tab on the diff spacer. Switch to that and the belt will not be so tight. So if you change to 19T, there is no more adjustment.

Does your inner wheel fully turn when your steering is turn fully?
My inner wheel not fully turn when my toe is neutral. Have to toe out then the inner wheel turn fully.
Coz when the steering is turn fully, the outer wheel turn fully 1st and locked , this prevent the inner wheel from turning further.
Do u encounter tis scenerio?

I have tis problem went i use 2mm kickup with 13deg camber,but after a few minor adjustment with no kickup,i get it rite.
There a small stopper attach to e diff cover,cut it flat n cut its steering turn buckle a little bit short if u cant get ur steering to 0deg toe then u should have 0 hackerman in full lock.

Regarding about those street jam wheels. My tires easily pop in and out of the rims when hit the tire markers.
Seems that sponge tape use to hold the tires is not working.
Did you glue it ? Wat kind of glue u use? I try CA still pop out.
I am using those old school rims.

Im using 'ZAP CA' its a thin CA.im using tis for my SCT tires n it work on my drift tires as well.u can find tis at almost hobby shops locally.

Regarding about the Ta05 front oneway, Wat is the thickness of the spacer you put to make the diff. pulley centred?
Where can i get those spacers?
