These are softer and more flexible than the box ( hard ) ones.

I had them installed on my Pro 4 and they feels great.

what did the change for you. (i guess traction). but what else?

do they work better on some tracks and not on others? and do the break easly??

They r softer therefore break easier, just broke the front left one today. Had more serious crash in the past, never did it once break the box ones.

i'm not sure 100% but high traction arms where supposed to have more flexibility so they don't brake as carbon plastic as carbon plastic arms are not flexible at all.

i have them installled on my car, never broke any for 3 months now.. though before i've brone 1 carbon plastic arm.

Is it possible that Hara didn't do as well as i thought with the pro4 becuase he is used to driving a belt car? If you look at him now he's beating rheainhard no problem with his new car.

moot

what rubber tires do you guys use? i put a brand spankers set of sorex 28's on to use at a meeting today.and on medium grip concrete,it destroyed both of the front tires with 3 heats and the final. i really would of thought that they would have lasted longer....

if you want them to last longer try the 32r sorex the last a long time and still have grip. this might help.

Here's an update on my big race.

Did very well in GP but since this post is about pro4, will just center on this topic.

Qualifying was real bad. Was using 69spur/25pinion and my camber set-up was detroyed. Landed in Class B 7th on the Grid.

Fixed my camber up, and followed ur suggestion.
Geared my 10x2 V2 at 72spur/24pinion and I was flying.

1st finals, got 2nd all the way from 7th.
For the next 2 finals though, a few accidents made me finish 5th overall.

Good enough...I was pretty happy with the performance of the motor. Thanks for the advice.

I am quite sure that Hara won with the Pro4 during the DHI Cup 2005. Marc was 2nd.

Can anyone help me with the setup of my car on the above mentioned track conditions? Currently, I use 50 wt shock oil on all 4 shocks; gold (stock) springs on the front and silver (stock) springs on the rear. I use Sorex 40R tires with red soft medium inserts. The track is quite technical. My car has ZERO kick-up and anti-squat. I use 2 degrees rear toe-in blocks and 2 degree caster. I seem to have a problem with rear traction. Steering seems to be fine. I use front one-way and no sway bars. How can I improve rear traction and the overall performance of the car?

BlackKat

I get mine on Friday or Saturday. Either gonna run it Saturday or Sunday If not I'll just run 12th scale my next meeting.

Anyone else here besides me & Axel run rubber tire carpet?

ME!! Indoor carpet rubber 19T...

BlackKat

The guy I'm getting the car from says its dialed for carpet on rubber tires BUT it comes pictured with the spool & one-way included laying next to it, and he says/shows it comes with a spool, one-way & diff. A dialed rubber tire car with a front diff?

It comes with all the stuff and the seller has his stuff together so I'm not complaining about a poor deal (great deal assuming the drivetrain needs no/minimal work)...just curious if anyone else runs a diff on rubber?
