I'll keep my eyes open for 200mm "P" bodies that will fit this wheelbase.

Putting Metric rims with a 10mm bearing cup (F1, SP) on a 1/8" CRC axle is super easy: Boca bearing 3.175 x 10 x 4mm fishing real bearings. A 4 pack is a bit pricey at almost $32 per pack, but they are ceramic ABEC 5. But again, the option is out there if you have that pan car laying around.

Front bearings:
#FBK103-ZZ5/3.175 BORE Radial Bearings

Serpent parts for the rear by part number:
Rear axle cone and nut S100/120 (#411251) For the cone.
Wheelhub left F110 (#411289)
Diffhub F110 (#411290)
Diffhub insert F110 (#411301)
Diffhub lock pin F110 (2) (#411302)
Diff adjust nut F110 (#411306)
Rear axle F110 aluminum(#411309)
Rear axle F110 steel (#411318)

Can be taken from the CRC:
Diff spring washer (4) (#411166)
Diff washer S120L (2) (#411186)

2 M3X3mm set screws.
1/8 diff balls.
Spur of choice, SP 72 48P bolts right in as does any Kimbrough.
LM body.
SP mounted foam tires.

Conversion steps, Swap front wheels and bearings. Unclamp left side WGT hub. Slide out WGT axle with diff. Slide in LeMans axle with center single bolt hub. Set screw left side hub into place. Put on the LM body of choice. Keep the Imperial parts together to switch back and forth in minutes. Used CRC Pan cars can be had cheap and need very little bling.
This is from our local racing thread. WGT doesn't exist here in Madison, so LM is our local popular class. I tend to keep stuff around, so I'm showing the locals how easy it is to convert to this class with one of my WGTs and one of my F1s.

SP knuckles, king pins and axles or Serpent king pins knuckles and axles should work too. You might need the upper pivot ball too for either brand.

I wonder if the WTF-1 parts will make this conversion easier.......I will have to ask the guy that has all of those parts in front of him....oh wait, that's me.

What are the rules for this class?

The WTF parts would be the hot ticket. Those parts are for sale when??? Or just take a WTF and put the F103 special front bumper on it. TRG now makes a version of the bumper. http://www.ebay.com/itm/TRG-TRG5094-...-/130602955283

It will take a standard servo just fine.

You won't be able to get the output shaft of any standard servo centered on the Gen-X 10 chassis; so, the geometry of your steering will be compromised a bit. A mini size servo will let you position the output shaft in the center of all CRC Gen-X 10 chassis. A mini will also allow you to do the reversed servo placement on the SE chassis. Can't do that mod with a standard servo.

If you use the stock servo mount holes it won't line up...but if you go old school and drill your own servo mount holes it should work...or just shoe goo the servo to the chassis. If you mount the servo to the front suspension plate you won't be able to get it to center.

Futaba s9650 servo. And one of these Kimbrough Servo Savers.

I have used the KO 951PDS and the JR Z3650 servos. For me the JR Z3650 is both cost effective and bullet proof for durability. I have hurt one KO 951PDS; but, not without great effort...LOL

Always match with a Kimbrough #201 (or #200) Mid-Sized Servo Saver. #201 is predrilled/#200 is without holes so you can customize hole locations.

Newbie needs help. Been running oval for years but want to try some road course. Figured a WGT car would be a good start since it only has 1 shock and I can use my 1c batts, tires, 13.5 motor, servo, esc, etc... from my 13.5 spec car. Have a CRC x10 and am trying to get it set up. So here is my question:

If you put it on a 4 scale board, wouldn't you want the weight on the rear tires to match and the weight on the front tires to match since you are turning left AND right? How exactly do you do that? The battery, servo and esc are centered. The only extra stuff is the receiver pack and the receiver and they don't weigh much. Also, with rear tweak springs set equal, car has a TON of tweak in it. What am I doing wrong? By tweak I mean when I lift the car from the front the right front wheel leaves the ground WAY before the left front. Car is right rear/left front heavy.

Which model of CRC Gen-X 10 do you have? Makes a huge different between the old "Pro" version and the "LE/SE" versions.

LE with a 9650 servo, a 1 cell mounted forward, a Tekin RS Spec mounted behind the battery and a Revtech 13.5 mounted normal. All that's left is the receiver and receiver pack.

Took off the dampener tubes and unscrewed the tweak springs all the way up. Put the front wheels on scales and the left front is measuring 221 g and the right front is measuring 159 g. Going to pull the front end apart and rebuild tonight to see if I have something off/bent/binding etc. but that's still a pretty big difference. Even if I put the receiver and pack on the right side the balance on the front only changes about 5 g.
