if they are not breaking and crashing ? pretty impressive for newbies....they shouldn't be running as newbies then. If that is how it is at your track...imagine the expert class at that track...must be like pro level.

Are you using the shortest lower spring cup? There are different sizes.

I would like a little more info on this as well.

For the person with ride height issues, there are also two different length plastic links for the end of the piston rod. If you have the wrong link and wrong cup that could put you significantly out. I'm running blue rear +3 and getting the car to 16.5/17mm for turf.

Been running these for a while on the EOS carpet style tracks where there are lots of flat landsings.

The B64 arm is stiffer in the vertical plane and any flexing of the arm is undamped hence the spring back causes the double bounce on the less stiff B6 arms.

Other useful points for high grip is that the wheelbase becomes 3mm longer and the ARB mounting point moves out on the arm. Both these things help the car stay flatter in high speed high grip corners.

To make the most of the modification you need to space out the lower shock mounting by 4mm (make sure you use long enough screws to prevent failure of the arm at the screw holes) and use the short shock standoffs (same as the front) on the rear tower.

If you hit EVERY downslope and you have no high speed sweepers on your track your track you may not notice much of an improvement.

Hope that helps

Yeah zero issue feel free to watch some of the videos on the clubs youtube page. Clubman is the 10.5 class and mod is well mod. Yesterday was my first time driving in over 10 years and the 10.5 was just fine. I didn't think it was fast at all to be honest

Thanks RogerM, that sounds like the B64 arm options is decidedly a carpet mod, since the dirt guys are drilling a 3rd, inner hole on the B6 arms to go softer.

New build. Only 1 race old :tire:

Hmm, sounds interesting as I only race carpet during the winter.
If I would try that, what do I need?
Rear arms&hubs? (+what you wrote above for the shock mounting)

The gentleman who sold the B6D to me said that the diff thrust washers have a very slightly different inner diameter and I can't remember which one went first on the bolt. I measured only .05mm difference but he does know what he's talking about. I have to ask him about it tomorrow but have any of you heard about this?

Unless they are aftermarket, it doesn't matter. The stock ones are identical. I would call a 0.05mm difference within tolerance.

I'm using the 5mm spring cups per the manual. Should I be using the 0mm?

Are you sure he didn't tell you that the thrust balls are a smaller diameter then the diff balls?

Yes. Shortest cups and shortest shock ends. No problem getting it low. Screw the shock ends on according to manual. Measure the shock shaft.
