Malc,

Can I ask what 19t motors you and Ben were using and what gearing?

Cheers,

I run the same tire at an indoor track in So Cal and they certainly don't look that good after 6 runs. And I NEVER rotate my tires, BTW; they are always labeled 'left front, right front', etc and always stay that way.

I ran my JRXS last week having moved from a Tamiya TRF415 MSX and it was fantastic with the kit setup - I would say as good as my tuned 415.

The car went together really well and for me it just feels smooth and predictable. Great car - recommend it (and we could do with as much support as possible in the UK!!)

I built the car as per kit setup and it was fantastic for the track I was on last week. I am racing on a less well prepared (read bumpy/rough) this weekend so I am sure I will make a few changes such as kickup, softer oil/springs. But it is defintely the best car I have driven in a while... and the last three cars I had before the JRXS were a Pro4, an RDX and a 415MSX

The batteries and motor in the middle make the car transition from side to side very well and the car accelerates very quickly indeed.

Great car, go on go for it - you know you want to!!

Bill,
My steering link is mounted in the back position and I'm running a spool (per the Numan setup). I've never seen this sort of tire degradation before, generally its across the entire wide of the tire .

This is the second set of tires this has happen too, and a fellow racers (running a Cyclone) is also getting the same wear, but some others are getting 20 runs and more from there tires . So you think this is normal and the tire is overheating and I should run larger holes in the rim...

personally, i think you need more front traction and less wheel (steering throw).

your description says you have to turn the wheel too far to get the car to turn effectivley. dial more steering into the chassis and your tires should last as long as others are getting.

P.S.. these are just thoughts, i have not had rubber experience in years..

Keih-I just had the worst hour of RC!!! I broke the car twice and bent the steering rack-what the heck is wrong with me? NO mo jo. Anyways-I know the set-ups got a lot of potential. Lots of steering!! I changed my bump steer and that was really big. More like how your set-up.

Yes you're probably right... I've heard this discussion before and struggle with not have 100% steering throw. It's probably a psychological barrier . I need some couch work

Hey Guys,

Here are a few links and pics of the KB rear shock mod w/rear sway bar.

Mount Spacer
Sway Bar Kit

Bolt the spacers/stand-offs to the tower and using a second plastic bar as a backing mount the two w/bar to the spacers/stand-offs. These spacers/stand-offs give the perfect spacing as the link will mount even on the bar giving you options of moving the link to the end of the bar or in closer to the pivot.

Another thing I have found with the KB rear shock mod is if you drill the body mount for a lower second hole and use a pair of the included front/rear pivot 2-hole spacers in between the body mount and shock tower, this will give a perfect centered body mount. to keep the mount straight install a second screw in the new hole. (look at body mounts in the pics below) You can go back to the stock rear shock tower/mount position without redrilling holes in the body. To re-install the stock tower/shock location just remove the 2-hole shim/spacer and install the body mount on the front of the tower. It will line up with the body holes perfect.
