I just ordered 1pcs of the Excel part, just to see what it was.
It included 4pcs of the graphite spacers, two for front and two for rear. I think Hara was using the same parts at the ROAR Nats.
The 2mm washer under the steering link ball stud is located out by the hub, this will do the oposite of lowering the graphite steering plate. Again this will make the car more predictable and easier to drive!
Tip: Make sure your diff outdrives are in good shape, when they are worn you will loose steering and rear traction!!
The Delrin diff will make a big difference + it last allot longer!!
Good luck at the KO Race, I had plans to go there, but I have other commitments that weekend.....
Cheers

Thanks will try that 2mm washer on the hub. I am using the delrin diff outdrives with associated diff screw, t-nut, spring etc.
Thanks I am really looking forward to it .. pity you can't race cos it is apparently really good. Will let you know how testing goes ... I can't wait to try the changes.
Was looking at the old 22's I stripped off my car last night and one of the rears had come unglued from the rim ... that was also prob part of my problem ... what a muppet I am I didn't even check during finals...
Anyway my new sets of tires and inserts and wheels should arrive today ... Most of my old ones went in the bin last night.
Cheers
Scott

Scott,
The Graphite shaft is really good, there is no vibration from the drive train at all...!
With the stock shaft you can feel and hear the shaft vibrating!
I know it is expensive, but I think it is worth it and it will last forever.
Maybe I can make it down to England next year, we will see!
At WLRC you might want to try a spool since the track is really small and low traction.....

Gearing on carpet
For those that have ran the car on carpet, Mod motor, what kind of temp. is your motor running?
I ran a Reedy PT 10x1, new tires (61mm ?) geared at 98/25 and the motor was a 150*. A little warmer than I like.
Our current layout is super tight, almost all hard on the throttle, off and on again. Not much room for the motor to wind out.
take care
john

Aluminum knuckle arms
Does anyone know the other manufacturers who make the aluminum knuckle arms for the Pro 4? I know GPM Racing and Jet Racing make them, but I forgot who else does. And also, which ones are the strongest? Thanks.

I am off to try the new car setup this evening ... that is if it doesn't rain like it looks likely to do.
I have a homemade spool that I will take and try in practice, wish HPI would bring out a spool .... I heard they were going to release one soon but since then have heard nothing ....!
Yip the KO is definitely worth a trip ... that is if it doesn't pour.... I must try to get over to Europe sometime ... you guys have some awesome tracks ..!
Cheers

How many people have 2 Pro4's? I bought a second kit a while ago as a spare but have never got round to building it.
Thought it would be useful to have a spare at the track but now can't really see the use ... ! Setup would be different and I wouldn't be able to afford all the Hop-ups I have bought for my race car?
Anyway just asking generally if there are many people that have 2 of the same car
Cheers

people i know usually use the second car for parts if they have one, perhaps its cheaper?
