Sorry with my bad english.

My guess is that it keeps the body from bending down under high aerodynamic load from the rear wing at high speeds.

The rear post keeps the body from tucking.

I think you were talking about the body posts..

The body post facing out I also use on my NT1 just to protect the rear of the car in accidents....

Hara's car had them.. not that anyone was quick enough in SS to hit the rear of him..

Anyone know if a Hara or Andy M Eddition of the TCX is going to be realesed anytime soon?

Where can I find the poundage ratings of the springs? and I have looked for places to buy the pink springs but can't find them. Thanks again
Hello Kobiwan,

In response to your post, I worked on a tiny project to fit a smaller spur and larger pinion. With this mod I was able to fit a 96 spur and 49 pinion giving me a final ratio of 3.84. I used a reamer to make the holes in the spur, I am sure a drill press or dremel would look cleaner.

I spent less than ten minutes to make mod.

Look at the attached pictures=>

Thanks for the reply. I'll probably end up doing the same thing. What brand of spur is that? Looks like a Kimbrough.
I ordered the Xenon 110 tooth spur today hoping it would work, but I think it will still be too big. Do you think they will eventually realize that everyone doesn't run mod and make smaller Xenon spurs?

Hi I just finished building up a friends TCX and thought id share some amateur photos.
A couple of things I did was add a .19 shim in between the c clips and piston as there was a bit of play.
And add a .25 mm shim to the sway bar holder screws as it was tight on the bar.
Other than that is awsome to build!
oh yeah it takes a 48p xray spur upto 87t

I will be running 17.5 with spec speedo. (no boost & no timing) What would be a good starting set-up? I am caught between trying the kit set-up or Hara's Super Stock set-up. Any suggestions?

Hara's super stock setup is closer to what you'll most likely end up at. When I first got my car and tuned it for my track, I ended up with a setup very similar to Hara's.

Haha, I would have tried my fifty but it's in the 12X.

Kobiwan:: I used the Kimbrough for this mod. I am sure there are other spur brands you can use. Just be sure to leave something between the teeth and the hole you make so it remains firm. You don't want a soft spot. The pinion may stretch/crush the teeth with the torque these BL motors put out.

What size hole did you end up with when you were done?

It looks to be around 4mm. It only needs to be large enough to see the objective. So mine may be larger than needed.
