That gives the car front kickup, a little less initial turn in but more mid and exit on power steering.

Thanks BTW ...I really liked your KO setup from the nats, looking forward to trying this setup on the car, I have a setup that works pretty good in practice, but haven't raced it yet, I''ll throw this on during practice and compare the two

Hey do you have a "working" modifiable pdf file? ...the one from the xray site won't open correctly on any of my comupters says "error 9" or something like that.

--------------------------------------------------------------------------------

I have a dry differential

The differential has been built per factory specifications and this way it has been build for several years by well trained factory assembly staff with great results. The diffs are being build and set-up for ultra smooth operation. All factory team drivers have been using the original diffs without modification or re-assembly which is a proof that the diffs are build ready for any high competition conditions. There is a thin and sufficient layer of grease put on the large diff shims, there is sufficient amount of grease applied on the carbide balls and there is sufficient amount of grease applied on the axial bearing as well.

You will not find any extra amount of grease in the differential because XRAY differential has been build for smooth operation and features only the neccessary, appropriate and sufficient amount of the grease. If a large amount of grease would be applied, this will make the operation of the differential not as smooth and efficient like it is now - built per factory specifications.

Moreover XRAY differentials feature the XRAY Dust-Covers which seals the differential perfectly and no or very minimum of dust can get into the differential. Therefore even a small amount of grease is sufficient to make the differential work smoothly and perfectly for a long time.

Please note that XRAY has been using a very special grease which is very thin and transparent so it may look the differential is dry. XRAY strongly suggest NOT to use any other grease than the original XRAY grease.

To summarize the answer - XRAY differentials are NOT dry. If you do not see any overflowing amount of grease in the differential do not worry, your differential has been built properly with thin and sufficient layer of thin grease for smooth operation of the differential. If you believe you need more grease than is the factory standard, then please use the included grease in your kit but remember that a larger amount of grease may make the differential run not that smooth. You can purchase the XRAY Grease under part number #30 9500 Silicone Grease

At the end, please remember if you want your differential to last long you need to break-in the differential properly. We will add another FAQ section about the proper differential break-in.

Having the arm "kicked-up" like that calms the car down, to me. I did that because the car would get to rear-end happy going into the chicane on our track.

Thanks, about the nats set-up. Ya, I have a modifiable set-up sheet, its what I have been using. works for me, using Adobe Acrobat 7.0 Professional on a Mac.

Is that a diferent top plate. Does it come with those mounts that connect the top to the lower chassis.

X-ray, PRS, and Parma gears fit perfectly. ( X-ray and Parma have a thinner center section than PRS gears and thus provide a better clearance from the motor mount )

Kimbrough gears will fit if you mount them with the tooth marker facing the belts and loosen the motor mount bracket and pull it away from the centerline a bit and retighten it. Without the extra finageling they will work but they will rub slightly on the motor mount.

Robinson, HPI, Tamiya, Kawada, and atlas gears do not fit.

Corally and Speedtech gears will probably work but I have not tested them on the car.

Related to that post from Mario Hudy...I've just run my 05 about 6 times and the car has been fairly inconsistent. After the last run, I checked my rear diff and it felt very gritty...almost crunchy so I took it apart. It was BONE DRY. The thrust bearing had exploded from friction. When I opened the diff, thrust and diff balls and metal fragments fell everywhere. I ran my hand across the thrust and diff washer and my hands were clean. No lube of any kind. Even though I run the front diff locked, I decided to check it too. Same thing...trashed thrust washers and bearing. If he believes those diffs are being assembled properly, he needs to go have a chat with quality control.

Rebuilding those diffs was a pain too. Those freakin snap rings are bitch to get out

Robinson gears work just fine...you just have to drill 2 new holes for the mounting.

Yes, that is the optional wide top deck and the stand-offs are separate.

Does anyone have a modifiable Xray FK 2005 setup sheet I cant seem to find one.
