I don't have the car in that configuration anymore. It was too unstable. I converted it to a FWD rally car.

Hey guys, I got a question about the REAR turnbuckles for our XV-01.

What Tamiya chassis has turnbuckles that are compatible with XV-01?

Thanks guys!!

I love the articulation that you've managed to achieve on your rally car. Pretty awesome. I guess it follows that you have a Subaru XV crosstrek body. AWD action!

The dog bone angle is amazingly at its limit in the rear. No binding? I would be weary of might fly out under hard power.

Interesting is, that with this ride height, you need longer shocks than 75mm on the rear for most of the mounting positions. So I have shortened the 85mm TA shocks (27.5B/27.5S) that I was planning to use in the front to ±80mm, and used them in the rear. I think I no longer need these longer shocks in the front, because the 75mm (23B/21S) TA shocks have little longer travel than 75mm Gmade, so now I have all the movement that I need there.

With this setup, there's obviously a lot of weight transfer, but the car is not rolling in the speed I can achieve on our tracks (I guess, I can only test it at home, as it is freezing outside).

I did suspension tuning using the method I have referenced yesterday, and I have to say that it makes a lot of sense. First thing I have realized when I have dumped the oil from the shocks was, how different natural frequencies I've had front/rear. After some spring changes, I now have a combination of springs and mounting points that give me the same frequencies front/rear, plus the desired ride height. What is surprising is, that it rides better than before even without any oil :-).

BTW - I've been complaining about spring selection for Gmade shocks. To my surprise, I've just found out that the 45mm long springs for 12mm BB shocks (TA, TD, etc.) fit Gmade 75mm shocks without any problem! I'm really surprised that nobody mentioned this anywhere. So it seems that I have plenty of shocks and springs now :-).

They measure 3x23 due to the narrow suspension on the rallye arms. I don't know any current cars that use those turn buckles.

The TC version uses 3x42 in rear which is common the TA cars.

Anyone in california? I would like to start a rally series like this one. Lots of XV-01 rally cars. I'm happy to hear everyone here enthused about their xv-01 rally cars. All I gotta say just keep on spreading the word cause a nationwide event is bound to happen. I was at my LHS and I saw 2 xv-01's sitting on the shelf. I get excited everytime I pass them hoping people as passionate about rally cars find these. I will admit I was a lil late on the bandwagon, but if I can find a few guys near me in La Puente, Ca. whose interested in rally we will start it. Keep posting new threads. I got one in California, still waiting replies, lol! Peace out!

Word! I am in Los Angeles. I am interested!

La Puente isn't too far. I goto Tony's occasionally. Which hobby shop has these xv-01s? Tony's? Also what hobby shops do you frequent in that area?

Ok, got it!

I have the XV-01 TC Pro. It was sold to me by a friend who bought additional parts to make it rally spec like the XV-01 Pro. It has the 3x32 tie rods (from TC Pro) on the rear giving the rear wheels a positive camber which I personally don't prefer.

I think I'll buy the 3x23 tie rods to make some changes.

Thanks Raman!

Some of my touring cars have slight positive camber in the rear to achieve even tire wear, but only slight. If it's more than that, then yeah, you need shorter turnbuckles.

Yes, Fyrstormer. I've noticed in the stock set-up of XV-01's that there is a slight positive camber but that is good for the car, as far as I know.

By the way, my 'converted-to-rally' XV-01 TC comes with this Front Direct Coupling “Spool”.

Is it good for rally or will it be bad for the kit in the long run? I'm only using a silver can motor and not planning on using a more powerful motor anytime. I don't have a slipper clutch as well.

Thanks dude!

Make sure you pick up the 3x23 steel ones.. not the blue aluminium .. they bend too easily. I tend to upgrade to the titanium ones for the long run which can be costly.

The drive cups tend to wear quicker with a spool, that is why they are usually hardened steel.

The effect of a spool is more noticeable on high traction.. where it allows greater corner exit speed at the expense of corner entry, which results in understeer.

Since the XV01 is front heavy, you will already have plenty of steering, so tight front diff or a spool will actually reduce the tendency for the rear to over steer. I never bought the spool for mine but at present run 2.5 mill in my front diff

The front spool is a matter of taste, if you like the way the car drives with it then don't bother converting it to use a diff instead. Spools are lower-maintenance. I have the front spool on my rear-motor XV-01 road car, and on my FWD XV-01 rally car.

I always install the slipper clutch if I possibly can. I like having the ability to mechanically limit maximum torque as necessary. My FWD XV-01 rally car, in particular, would be impossible to drive without torque-limiting.
