i tested the whole set a while back ...
4.25T - 35.8 lb/in
4.5T - 31.7 lb/in
4.75T - 29.2 lb/in
5.0T - 26.2 lb/in
5.25T - 24.9 lb/in
5.50T - 22.9 lb/in
5.75T - 21.2 lb/in
6.0T - 20.0 lb/in
6.5T - 17.9 lb/in
unless they made some changes, it's a fairly usesless set on rubber. btw - i have two sets for sale should anyone disagree with me.

To tune the car you need to use a different company spring Tamyia,HPI,Xray,Yokomo,AE ect. 4mm shock towers help to get the ride height and droop settings.

The M-03 plastic servo mount with a 10mm bolt works fine as a battery brace up front. In the rear the bullet connector from my lipo pack just touches the upper deck and keeps the rear of the battery away from the belt.

If you are having issues with your car then something else besides the springs are the problem. The spring kit is probably one of the best investments for this car. I have tuned for high traction carpet, low traction carpet, asphalt, seal coated tennis court, and concrete and never had to look elsewhere for springs.
Chassis set up has everything to do with spring choice. I have run the softest to the hardest spring and everywhere in between depending on the surface. Even one step up or down makes a big difference. If the spring kit came with anything softer it would be unusable because it wouldn't support the chassis.

Those springs are measured at 14lbs. I also have 6.5 3Racing springs, which are much harder. Infact, they are slightly harder then trf mini blue, which are 17lbs. The 14lbs support the car fine. I'm confident I could run 12lbs if I wanted to. I'm running 6.5mm ride height with those 14lbs trf mini springs by the way.

I'm using tamiya yellow mini springs all around on my XI. Standard shocks (threaded), standard retainers, standard towers.

Maybe one thing we should be considering in car weight. I'm running 1550g in race trim for the vta class. If you guys are running a much lighter tc weight then I can better understand the lighter springs.

All good ideas to keep the battery off the belt though!

What benefit have you seen from running a very soft spring? In my experience I have never even thought of going softer than 6.5.

Please continue discussing car setups, but in the terms of setup. I have yet to see an Xray or TC6 setup sheet that claims all other setup sheets are wrong. Scott and I run the same track in the same conditions, in the same class no less. His car setup is about as different from mine as possible. Pros and cons, go go!

Couple things to keep in mind:
* The Sakura Zero shocks are shorter than "normal" touring car shocks, so when using another brand of springs you need to that that into account if you don't use the other shocks as well.
* If you use other brands of shocks you either have to build them short (put a 4mm spacer inside the shock body to limit travel) or get the +4mm shock towers.
* Some brands of springs are progressive (they get stiffer the further they are compressed). When you set your preload or use them in any way shortened you will typically be "losing" the softest part of the spring.
* Spring rates are normally posted as straight compression rates. When you lay the shock down (change the angle the shock is mounted at) you change the effective spring rate. A vertical shock is "harder" than one at an angle.
* The oil you use impacts your spring and vice versa.
Scott, Grant and I all race at the same place in the same class. All of our cars are setup differently as we all have different driving styles. While our goal is the same (Winning!) we've all taken different routes and monetary outlays to try to get there. That's the part that needs to be focused on here. There isn't a right or a wrong, just ideas and implementations. What works for you may not work for someone else. What is working for me right now probably won't work as well this summer when the track goes from it's current high 60Fs to high 90Fs. It's all about making it work for you.

Hey guys,
Just a question about the steering systems from the XI.
Are they a straight swap for the system in the zero or do you have to make some mods to the chassis?

cant see why you should need the xi steering? is the steering system on the S bad? (never seen it irl)
i drive the xi, nice car, but the steering has developed ALOT of sloop now, its so much that im thinking of replacing it.. (50packs with the car, indoor on carpet)

The steering in the Zero isnt bad... But mine came apart last race and it doesnt have the same feel as it used to... so it needs to be replaced in the not too distant future... was just wondering if the XI steering was better and if it would slot straight into the Zero

I have the aluminum steering setup for the Zero in my car and have been quite happy with it so far. Interestingly enough, one complaint I have had from a friend driving my car (and an issue he had with 2 other Zero's) is that when he completes a corner, the car tends to overturn and the driver has to correct back. If I think about it, I will bring the wheel back to center a hair sooner then feels right, and it tracks out straight. No idea if these are related to the servo orientation, but I am kind of curious to try now...

Ordering this car as soon as my pan car sales. Wondering if the futaba 9650 servo I was using in my pan will work ok in the touring car. Was thinking of upgrading it to metal gears eventually. They are .11 speed at 6v and 63 oz of torque.

That's a mini sized servo. The mounts in the Sakura S are for standard sized servos. I use a Savox SC-1257TG servo in my S. It is .07/139oz at 6v. Overkill, I know. It was in my FTSC10 before I sold it.

Hey Grant,
How is the steering servo position different on the Zero S and the new XI?
I see that the new XRAY mounts perpendicular to the driving direction of the car, but from the pics of the XI it looks to mount in-line like the S...
I actually ordered the XI steering for my car as I feel like the plastic steering on my car has a bit of vertical play. I was not able to find the metal Zero steering so I ordered the XI one.
Thanks!!
