Cite please - post a pic of Rivkin or Cav's car with the body off.

BT and Kody said they used the Reds Work Shop setup at warmup, but made some changes to it and built their own.

You can not buy the setup Rivkin, Cav and Kody were running.

Wonder what the lowered shocks were for... up travel limiting to prevent traction rolling? Certainly not additional down travel, right? Wouldn't that be about the worst thing ever on that surface? While I won't be racing on this surface any time soon, I'm definitely interested in the setups they used.

EDIT: Figured out why they lowered the shocks down: The rear hubs mount the arm lower in relation to the axle so the shocks need to be moved down to allow the wheel to retain similar down travel as before.

Probably close to our carpet setup state side. 1.6/1.7 35/30wt. Blue springs all the way around.

Actually know Spencer was running orange/blue

all according to red. as far as we know the only difference between the two is the new carbon rear tower with the shocks on front of the arms

There is actually quiet a few differences, some subtle and some more obvious and all work to further enhance the cars performance for the turf. Saying its the same transmission and such as the reds setup would be a bit misleading.

These modified B5Ms were only done for a Rivkin, Cav, Cragg, Hartson, McBride, and Kody. However, other non-salary team members ran a Reds setup.

That pic is NOT Cav, Kody or Rivkin's car.

Like I said - they did NOT use the Red's setup at worlds - they used the red's for testing, then made their own.

sorry for the misleading writing in my og post but i meant to say it was reds version of the worlds 2wd. he made changes to the gearbox and hubs that are pretty cool and add a lot of adjustment. idk what geometry changes ae made for the top guys's cars but they certainly worked.

Currently running a B5M Lite with Rivkins OC/RC jconcepts stock nas setup, don't feel like im getting the amount of mid-corner steering I should. Any ideas on what to change from that particular setup to make it more aggressive mid corner?

I thought I read somewhere buried in Red RC's coverage that the "salary/Factory" Associated guys were running prototype pre-production Associated made gear boxes, hence the forward mounting shock tower off a B44. So they were custom made by the team, and they might eventually release them as an option part is what I understood.

Everyone else at the worlds driving an Associated branded car used the Reds setup posted above, but not the Factory drivers. The two setups are vastly different.

Yes, that is mostly correct, only the salary guys got 'Factory modified' B5M's, which were specifically optimized for astroturf. Also, the rear tower is not off of a B44, it was custom.

Found this pic from Worlds. This car has a few new JC items - chassis, shock caps, shock collars, etc.

Also, those nifty new JConcepts cv drive shafts. Would love to get my hands on that chassis to test on some high grip clay.

First think I would change is a simple roll center change to the front of the car. The best way to lower the roll center in the middle of the corner, but not necessarily change it at initial input, is to maintain the same static camber link angle, but lengthen it. This will minimize how much the roll center rises, the more the car leans.

For more aggresive mid to corner-exit steering I usually prefer to raise the rear roll center. Either taking out 1-2mm off the inner rear camber link or perhaps even going a half hole shorter off the hub. However, if you go to far the car can become much more twitchy to drive and almost 'wandery'.

By raising the rear roll center relative to the front roll center you are inclining the roll axis even more so that more weight is transferred to the outside front tire along with quicker weight transfer side -to-side in the rear making the car feel more 'responsive'.

My mistake, at first couple glances it looked like a B44 tower, but after looking at it more it does look custom. Interested to see some body off pics or know if the kit will ever be available as an option
