Hi guys,
I’m older…ish ,and coming to KZ after Formula Atlantic cars…
I have a CRG RR, Tm KZ R2. Set to 4mm toe out and -2neg camber…
Front tires show much higher wear on inside edge…. Is this normal for KZ, or is it likely too much toe out, or neg camber ??
Camber, caster, and toe are Sniper set on the stand, not on the ground…. One man show …
Thanks,
Bill
Pretty standard for the insides to wear more than the outsides. It’s common to flip tires on the rims to even out wear, especially if just burning laps. You can run a range of camber settings, some like more positive and some keep in negative range. The more positive you add the more responsive the front should be on turn in, to a point.
4mm toe…I guess total correct? So 2mm each side? If that’s the case, then it’s pretty standard, as well as -2 neg camber.
Inside edge wearing out faster: normal. When you start noticing it, flip the tires on the rim and side to side (if you, like me, like to keep the direction of rotation constant) and you’ll wear them more evenly.
it sounds fairly normal, however I tend to prefer less on both accounts, about half of your reported settings. In the end it is all about making the kart work though, and that can mean different optimal settings for different karts, or even for the same kart in different conditions or a different track.
Something else to consider. Sometimes when negative camber makes the kart better, it’s because you’ve effectively narrowed the front track by moving the contact patches in. It could be more beneficial to go back to neutral camber and decrease track width via the hub position adjustments.
If “show much higher wear on inside edge” I’d be dropping toe out to 1mm as side and setting camber to zero and then get some feedback. Just for comparison I run zero toe and about 1/4 box of positive camber. And I still wear the inside edge more than the rest of the tyre.
Am I right in thinking a kart on the stand with say +.5 positive camber will inherit more negative camber when the kart is loaded on the ground?
Yes, kart on the ground and driver in will camber out.
I have run up to -24 degrees of total camber, on the KR, in high grip situations and on new tires.
and a new chassis after that session 
I would advise against zero toe, especially on the stand. In my experience karts gain toe in when on the ground compared to on the stand. You definitely don’t want toe in on a kart (at least in the dry). I run between 4 and 6mm toe out.
Hi Simone,
just confirming my understanding. When you say ‘on the ground will camber out’, you’re meaning it will move towards the negative camber side, correct?
As in it will gain negative camber from where it was set?
Cheers Ricky. Your 4 to 6mm is when on the stand I assume?
I must buy some Snipers!
That’s correct, on the stand.
Yes, it will gain further negative camber when load is applied, on the ground.
