Does anyone know if the new factory team tc3's come with clamp hubs and the aluminum servo mounts. Thanks

The FT kit I bought a few weeks ago had non-clamping hubs and plastic servo mounts.

Get a helicoil kit and use a drill press to install helicoils in the kit hubs, they'll never strip.

i saw that calandra makes some decent looking alum stuff, but i was wandering if it was me of a known problem, couse some of the guys at my local track dont have the problem

Like was posted earlier, I run quite a bit of 'roll' for stock and 19t. It does depend on the track. Your car should rotate well in order to take advantage of the higher corner speeds, otherwise you might think your car is pushing.

Has anybody purchased outdrives from Hardcore? And if so, did you have any problems getting them to go together correctly. Mine, are not going together. It's as if the (2) bearings in the center. (one in the outdrive, the other in the ring-gear) are 2 think and do not let the outdrive come together as it should.

Any thoughts?

I have 2 cars and both have them installed. Have not experienced your problem. I would try assembly without one bushing and see if the problem goes away. If so, hand file the bushings till you get the clearance you want. BTW, I had a guy machine them so they will take the stock AE "D" diff rings, makes life a LOT easier.

I just noticed that you said "bearing" not bushing. I would measure the thickness of the bearing compared to the bushing to verify the thickness. You might still try assembly with only one to see if that lets it go together better.

I will try that. I also milled the outdrive to accept the Dring. I'm sure that's the issue.

Do you have bushings installed vs. bearings? If so, doesn't this make a difference on how smooth they operate?

JWATT

I use bushings. The only time the unit uses the bushing is when it is in "diff" action, and a bearing will not be noticed over a bushing as far as smoothness or how free it "diffs". Be sure to assemble it clean, and use some diff lube on the bushings, and then if it is rough you need to look elsewhere.

Bearings over bushings in this application is over rated, IMHO.

I have the IRS aluminum diffs, they would not accept bearings either. I experienced the same problem your having when I tried to use them.

I just bought an aluminum diff hub and aluminum drive cups for the center shaft from IRS and NOTHING fit properly. Not only could I not get the drive cups on the shafts, but the driveshaft did not fit inside the cups. The diff hub had terrible tolerances on it and wobbled on the drve pin.

A quick e-mail to the guys at IRS explained that there was a problem with the anodizing being too thick on the drive cups and some QC problems on the diff hub. They were very helpful and willing to take back my parts, and exchange them for new pieces when they have fixed the problems, but I would say that my first experience with IRS parts was not a positive one.

We'll see how the new parts work once I send them back and receive the new pieces.

Does GPM have a site? I am looking for the GPM Aluminum TC3 Steering Carriers (Knuckles), but I cannot find them ANYWHERE! Any help would be appreciated.

CRC's look almost identical to the GPM's. I wouldn't be too suprised if they were the same. Although, I've never held the 2 together. The only place I know to get the GPM stuff is

The only parts I'd suggest from IRS on the tc3 are the light input shafts, alum outdrives if you run mod, and big dawg bones if you run mod.

The plastic drive cups and spur gear pieces are fine, and very true.

IRS makes some great stuff, especially their 12th scale parts, but I think some of their TC3 parts are uncecessary.

Use BUSHINGS in the IRS diffs. They work fine. Coat them in diff lube prior to installation.

Hardcore outdrives us bushings, like the ones that come with the AE lite drives, not bearings.
