The front belt looks loose, but with it set at normal position, it works just right. I have both side belts: the fiber one was way way to loose. The rubber one is just right. Make sure you don't put the 23 tooth in the rear.

theres been few guys here asking bout the pulleys too,well u v got to identify d pulleys and mark it if u can.
Side belt came in 2 pieces,u cant missed it coz d 24t pulley came in a plastic bag together wit d belt and d ratio chart.Ezier way is d 24t belt clearly state bando sts which is rubber.
D frona nd rear u shouldnt got it loose coz stock aasembly fits in with good tension.Currently i m using all around rubber base belt and yes it is great too,smooth,less dirt sticking,not ez damaged by small rock goin in..

I came across too wit d 2nd gear housing ouching the sway bar,well d it happens when u get to much drrop on your rear..but if u nid to have that much,then make d turnbuckle on d sway bar attach to d lower arm longer..

No, i mean the marks on the bulk head, there are total six marks on the front n rear, make sure you have used the standard one. By the way, front pulley - oneway + 18 , rear pulley rear diff + 19 , side belt - 23 or 24 + 18 attach photo can make it clear.(i hope from left to right 24, 23, 18, 18, 19)

Well, I saw RCFOOLS MTX4 run at the World Famous Kissimmee RC Raceway, where the 1/8 Scale / 200mm Outlaw Nationals ran. He had the new carbon fiber chassis under the car. He seemed very fast on the track, and intentionally ran into the walls, breaking the car. I was surprised to see the chassis didn't have a problem taking the hits. His engine temps stayed under 240 with hard driving.

What is the handling effect of adding and reducing shims on the rear upright ?

Is it crazy if I add 3 shims or 3mm on the rear up right ?

The more shims you add, the more rear traction you will produce with lower roll center. Not crazy, I've seen that before.

i always thought that reducing the shims on the rear uprights gave more traction?

The longer the camber length the greater the car will roll to the out side edge of the tire and that will give you more side bite.
