2 thumbs up... not just different set-up...but a boatload of option parts.
and it's only $75-100 more than the original kit! worth every cent.
car a tons of traction outdoors...
you'll be even more competative if you get the 3mm chassis for your carpet car...

Very true, i've been running my original Pro4 with no hop ups for one year... just as competitive as any other car i've raced against...

Thanks
Just replace the screw and diff nut with the AE part. For the diff nut, put the side WITHOUT the extension (that locks on the diff) in the outdrive. You may need to use a bit of force to push that in if it doesn't fit very well. I've replaced mine since the early of this year and no problems at all

Should be getting my hara edition in the next few days, does it come with diff lube and thrust ball grease? or do I have to supply that? Also what setup does it come with........ i.e Springs for a carpet or for asphalt setup? your input will help me get everything ready for when it gets here so I can begin assembly!

thanx
Steve

Pro 4 Hara Edition....the car is great right out of the box. The only things that I have changed are....softer sway bars, different springs. I have ran it at one race on ashphalt, and I noticed an immediate improvement in lap times versus my previous brand "X" car

What type of tires? Foam or Rubber? I can help if you run rubber. At Trackside we run a spec tire, CS-27s. I have a fair medium bite set up if you would like it. I took 3rd at the Summer Sizzler two weeks ago.

I was looking for a rubber and foam setup. Is there a large difference between the two? I think my local track runs both for stock classes. I would love to get any setups so that I can build my own from a good proven starting point.
