Has anyone found an alternative sway bar for this car? I have the largest 3r sway bar in the rear of my car but might want a larger one for the nose, I looked at all the Xray bars in the hobby shop yesterday and none of them seemed to line up. I'm currently using the 3R xi-sport 3 dot sway bar in the rear, was hoping I could find the equivalent 4 dot for the front. I'm assuming the 3 dot is a 1.3mm. From my testing and findings, these cars definitely want the stiffer sway bars on black carpet. I have been fighting traction rolling for weeks, once I went to the stiffer sway bar in the rear it calmed the car down tremendously, just a tad bit tippy initially and wanted to test a stiffer sway bar up front. I've got some more coming in from RaceVTA.com but given that they're for an older car I hope they work and 3R is still making them. I will say we do have a very punishing layout at Apex right now and my car has felt as good as it ever has, it just needs a tiny bit more stability and I'll be able to push the car for all she's got.

Right now I am using X-Ray 1.4 rear and 1.5 front on my Cero Ultra Ace and Cero Ultra V2 for VTA. Try doing some work with the roll centers to help it. I run 2mm under the inner front upper mounts and no shims in the rear in that same inner upper rear. Car was money with that on black carpet and the new tires. Kit Green front and yellow rear springs. I am surprised that EA doesn't have those bars on hand. He's slipping. Lol

Spent all day yesterday testing Mod with a different roll center and long camber link set up(new 3racing upper links). The day was partly sunny cold and windy we only dried the track and use “zero” prep. Also used the KrazedBuilds carbon flex chassis. Track surface temperature was 75-78 degrees. The long links were mounted on the top deck and on the diff mount (marked with red)

After a 14 year hiatus of not racing I was figuring stuff out and the car was good at the Winter Warrior Race. I have to get back into the rhythm of paying attention to the small details.

Cero sport mounting rear shocks to rear arms
Hi,I have the cero sport, my problem is I can not mount the rear shocks to the rear shock towers. The space is too long and the arm is so jacked in the air tire never touches the ground.
I have krazed build graphite chassis aluminum hubs with 8mm ball stud using spacer from kit.
built everything like manual says. Front shocks mounted no problem just rear shocks are driving me crazy by not mounting like they are supposed to.

Switched the shock towers, you were right. I feel stupid for not thinking of that, long build on this one. Thanks for the advice, am glad to get some help with this headache of a issue.

Been there, did that (but I stopped at 2). Also built the steering rack upside-down on the S64. Funny thing is, it worked fine that way.

I've attached my assembly notes for anyone who wants it. Most of these tips also apply to the Ultra (not sure about V2).
