No if the screws are just touching it will still have full movement.

Hi everyone. I race the BMI12R/BMI12RR in modified on asphalt. My set up is working well as far as traction, but sometimes I lack steering. The setup is close to the standard out the box setup except I use the short L-bar position. My other big problem is that I sometimes traction roll the car, what can I change to prevent this and not effect the rest of the handling.

Thanks...

Hi Jason or anybody else,

Can you please give me the part # for the long thin and std size flex plates for the DB12RR. The website is not so easy to follow. Not sure if the parts that I found are for the DB12R or the RR.

Also I have an original DB12 conversion. I want to sell it to a guy at racing but he is worried if he can get parts for it. Is part support still ok?

Thanks

Default my set-up

BMI12RR

Front:
0.020" springs
10 deg. reactive caster blocks
shims on either side.
kingpin shims - 3 on top and 1 above steering arm.
ride height 6 mm
40 SH ATS tires (44 mm diameter)
Servo angled - ball studs in center of servo saver position.

Rear:
30 SH ATS tires (47 mm diameter)
ride height 6 mm
Hard L-bars on short position

Center:
shock spring - gold
shock oil - 30 weight
ball stud - tall (BMI)
ride height 6 mm
batteries back position
antenna mount position - back
side dampers - 5000 weight diff. oil

Radio:
dual rate - 90%
This is my set-up. I tend to have under steer. If I change to softer tires on front, they wear out very quickly and after 4 minutes I am on the rim and back to no steering. The other problem is that the car traction rolls at high speed cornering.

Hey PHI/BMI racer,

Though I race carpet 1/12th let me see if I can help you... Im not sure how your asphalt surface is smooth or bumpy but your ride height I kind of high,set that to 4mm front and rear. Next move your batteries to the Middle position that will help with on power steering.

I dont know how your grip level is but you can go a little heavy'er on the shock oil maybe 45 or more.

Here's a little trick we use on carpet, if your traction rolling put some CA glue on the outer side of the front tires this stiffens the foam sidewall wich prevents the front foams from rolling over wich causes traction rolling.

Again I very rarely run asphalt so I hope this info helps

Hope This Helps Peace
Mike

Stiffen the oil in the tubes. Try going to 20,000 wt. and get the ride height down some. Also put 10,000 on the kingpins. Lowering the ride height will stop the traction rolls and the dampening will help the understeer. Also try running 35 shore tires front and rear. This is what i usually run.

Thanks, will try that next race meeting. The surface was smooth and good traction. Only problem the wear on the front tires was high, thats why I used high ride height. I think the ride height was the biggest problem, I ran my touring mod at 6 mm as well and it also traction rolled.

Caio...

Excessive push will increase tire wear. This is the problem. If you plant the front your tire wear will be drasticlly reduced. You should have your ride height down around 4mm

Just a quick question does anyone know if the IRS left rear hub on the DB10R is balanced the same and would the RC10R5 axle?
