It's hard to tell on the pics they all look the same.

Hey All, Still reading through all the thread pages and noticed some comments about the stock bearings being a bit sticky due to the type of grease the manufacturer uses. Does everyone suggest using the stock bearings after soaking them in D Alcohol or would you suggest going ceramic ??

YoDog !! How goes the chassis plate ??

just finished the programming for the 2mm prototype and may have it cut by this weekend.
I'm waiting on some additional funds to order the 2.5mm material.
I still got rear spacers and battery trays left!

You should consider doing a bundle of the spacers and the new chassis (no point bundling trays with the new chassis!).

Keep us informed - I'm willing to test the new chassis on the E4JS. I'm near certain it'll fit perfectly, with just 2 upper deck posts needed to replace the moulded front uprights.

My E4JS is also waiting on the new chassis. Does the rear spacer replace the upper rear bulk head? If so, I am interested.

It just attaches to the upper bulkhead as seen in the pictures.

Would that help in reinforcing the upper rear bulkhead or would that add more stress to it?

It would not stress anything it is rock solid..

It all depend upon the condition of the mounting holes. I prefer not to use the plastic upper bulkhead since I already have the aluminum ones. The bulkhead itself will not be stressed but there is a little added leverage on the screw holes which is why the spacer works. It adds a little more leverage from the rear spoiler/wing thus enhancing the down force.
On my car it feels very solid. it's much better than just adding a couple of standoffs which don't have as much contact area as my spacer.

Either way, were only talking about $15 bucks.

I'm asking because the plastic upper bulkheads are very weak thin pieces of plastic/ ABS. I've had it snap twice on me when using the graphite rear shock tower. When using the plastic JS shock tower, it is okay because the shock tower flexes and takes some stress away from the upper bulkhead. I'm inquiring if the spacer helps stiffen the plastic upper bulkhead but from your answer, it appears that the "leverage" from mounting the shock tower more rearward would stress the upper bulkhead more.

$15 for the spacer is a great price. Wish you had an upper bulkhead made of aluminum that is priced similar.

On my E4 FS I have the plastic upper bulkhead and run mod 4.5T last week practicing. It actually felt I have more rear traction cause it has little rear flex.

I re-read a few pages back about the spacers. Are these the aluminum ones for $15 each ?? Didn't see any mention of additional items needed to mount them. Are there additional screws needed?

Its nice when it works but its not so nice when it breaks, especially a little too often. I hope Yodog comes up with a good solution. How about a one piece upper rear bulkhead and spacer?

If anyone is interested I have a Dave Ehrlich Team Magic RS4 in great shape with lots and lots of extra parts for sale. I'm asking only $315 shipped. It's posted in the for sale selection with pictures. PM me for details.

You had that for about six months. Why did give up on it?
