With the optional camber link mounting holes, what would the handling difference be if I mounted the inner link further back? You know how the graphite camber mount has the four holes, in a two by two formation? I'm just wondering what the difference would be in having the camber link more/less parallel on the verticle plane...

front to back should have no effect practically speaking. on the smallest scale having the camber link at an angle relative to the swing path of the lower arm will increase camber rise, but the degree of this is minute. so in effect it doesnt matter.

the reason why the holes are not in a straight line (a la tc4) is that the extra holes are "half holes" taht is they are half way in between the other holes. naturally you cant overlap holes and still have strength so they just put the middle holes farther back (or forwards).

so only worry about where they are in/out not front/back.

Front pivot already 2.5, camber is 2 deg.'s have had a quick tinker today using your suggestions, will test tomorrow and race on Sunday.

Will let you know how goes.

Have done again, and did pick up a difference with front toe. Am not sure if that is enough to explain lack of front steering.

Will try out suggestions tomorrow, thanks for all help.

np mang. pro4 is a great car, there IS a reason why hara was so good with it, and its not exclusively because he was the best driver, its also because he had the best handling car!

just wait man, i plan on having the pro4 dialed beyond belief!


-----------------------------------------------------------------

has anyone else run pits on carpet with any success? i HEAR they are THE ticket for rubber on carpet, but i have no experience with them myself.
also does anyone know of a source for them?

thanks

RCMart has them for $19 but you have to jump through hopes if you are a new customer. Anyone know any other places to buy?

The camber and toe out, has just about done the trick!

Thanks for all help, much appreciated!

I'm going to ask a silly question..........

How fragile is the Pro4? Is it sturdy, or do you find it to break suspension parts easily?

Thanks!
