-Korey
I have had the US Spec car for about 6 months, it came drilled for the AE frontend, but I still run the Orig front end, have run the AE Dynamic F/End, waiting for the new CRC Strut set up to show. The Corally F/End has some great features, like wheel bearing choices, and the ease of setting Camber, spring rate, etc. It does lack (my opinion) fine hieght adjustment, and it has some slop in the strut screw itself, it is a little wide with some rims.

The Rear end of the car is where I see the biggest advantage, and disadvatages.
the Good
The Diff if built corretly is smooth and free, don't over lube, and yes full Ceramic bearings, on the poor side, wheel mounting screws, the head of Metric screws are larger in Dia then US stand screws, need to retap the hubs to acept US Stand thred, on the Drive side you need to take extreem care to use the correct length, if they are to long at all, they go directly into the outer Diff Ring.
The T-Bar is the easiest to change of ANY T-Bar ever, the mounts are smooth as silk, the key beeing the clam shell, with Mega O-Ring.
Ceramic Bearings can't ask for more here.
The rear Bulkhead Assembly Good points. One a piece unit, this in itself is great for alignment, and very ridged, top and bottom plates are well designed.

Bad points, One a piece unit, the Torq Tube is not replaceable, if you get, or Smack the Tube hard it can bend taking the bulkhead alignment out with it. The bearing holders are week to side impactm the bearing will push through if you hit the side of the tire hard enough.
Side Dampners, Well built, and sturdy, only minus here is there is there is no grooves for the lube to hold onto.

I wanted to add my 2p worth as well. I tried a 12sx for a few months but could not get on with how weak some of the parts were. For example, if you have a hit on the back part of the car, not only the t-bar, but also the bottom carbon plate would go also and they were not cheap to replace! One of the hits was not my fault (my car got rear ended by someone) and it still broke the t-bar and lower plate! The rear bearing holders were ok but the torque tube is cut too short so the bearing holders dont get held enough. You can get over the bearings getting pushed through the holder by replacing the standard bearings with flanged bearings. This puts some of the load at the front as well as the rear. The standard front end is great, you should really have a go with it before changing to the AE front end. Most of the people just use the AE straight away just because a certain world champ did! The guys at the local club run the standard front end as they are as fast as you like!!

has anyone come up with a way of strengthening the front arm mount? It isn't always obvious it has bent till the arms start to rub the spring posts. Ive tried a tie rod with rod ends b/w the hinge pin ends. It works, but requires the roll center be raised for the tie rod to clear the bumper. I currently have a pair of longer hinge pins that pass just inside of longer bumper mount screws, but I think the pins will bend. Any other ideas out there?

For those of you running the prism wheels on this car, you can use the outer race of gen x front bearings as a spacer for the 3mm offset. Its 1/8" (3.18mm) wide and should be readily available as these bearings are pretty weak. I just asked a gen x driver to save the pieces when he trashed a bearing.

We carry 3mm machined aluminum spacers for the use of Jaco prism wheels. They are high finish for the bling factor and also serve there purpose.

Jason- Are those spacers the right I.D. for the Corally axle? I think it's 7 mm...

If they are indeed 7mm then no. If you can confirm that, I will make ones that are specific for the corally.

What should an offroad racer turned off-season carpet newb/hack stock up on for parts for this car?

BIG cushy bumpers, .060 bodies to keep from crumpling?

To be honest mate, I would n't have a 12x as a first time 12th car. A little bit too fragile for a beginner. I would personnally have a 12L4 or CRC as a first 12th car because the parts are a little stronger and cheaper to replace!

Jason- rear axle bearings are 7x11 mm on the 12X, I don't have a 12X any more, but I did last spring and my 1/4 inch spacers would not work.....
