The Kyosho shocks are already excellent, so I'm not sure how much of an improvement these new shocks will be. I guess I'll have to ask Shin

Judging from this pic, I am not quite sure about he running the big bores on the ZX5... http://upgraderc.smugmug.com/Other/2...867_WRSty-O-LB

Of course, he might be, and I could be wrong...

[NitroArgi]

Yeap this pic shows stock dampers on the ZX5 but big bores on Tebo's 2WD!!!

[jimmy]

Perchance he only had one set to test

Perchance he is happy with the zx5 setup and doesn't want to risk setup changes at a big race meeting?

Perchance he thinks the big bores are all hype and only put them on one car to satisfy the sponsors?

Where do you get X-Gear springs?

And i have to admit - Thouse big-bores are H0T

Looks like the Kyosho spring part numbers infer that they ARE the X-Gear springs they are selling as Kyosho parts.



So does anyone know or have seen the Kyosho retail price in yen? Looks like that Japanese hobby shop price is really good, all things considered, but not knowing what shop that is, or how much they sell the standard Velvets for, the price isn't relative to anything.

Using the Kyosho site as a baseline, the RB5 Velvet standard front shocks (30mm) are $51.99/4,305 yen and the rears (42mm) are $54.99/4,515 yen, retail. If the prices listed as "discounted" by the hobby shop are any indication of street price, these new big bore shocks might be VERY similar in price to the standard Velvet shocks.

Definitely something to consider for anyone upgrading, or starting from scratch. You could probably still sell the small bore Velvets for close to what they are worth new, too, and re-coup some of the expense.


In that case, not a bad upgrade if they help the car and don't change the Cg/roll heights too much.


I would think on an RT5 or SC, they might even be more noticeable in feel. I wonder why Tebo used them on the RB5 and not the FS?

The japanese shop is RC Champs.
The big bore price is quite equal to normal triple cap shocks, seems that springs are more expensive.

This pic of the top ten cars is quite clear I think....

Yeah he seems to be running them on his ZX5 FS2, RT5, SC10 but not on the SP2 perhaps he is limited on how many shocks he has or just swapping them from car to car
There pics on the Xfactory website with his RT5 etc with big bores on

[SimonW]

I think you will find that unless they redesign the front shock tower they will never fit on the SP2, hence sticking with the smaller ones, and i guess the difference in performance would suggest that mix and match would not work either.

[major3d]

So the rb5sp2 will not have big bore shocks? I was waiting for the kit to include the shocks. Sounds like they will not be included and I should buy the kit now.

[RogerM]

I wouldn't mind betting that they will find there way into kits, Kyosho normally do updates on the kits when there are significant design changes but it is usually a couple of months or so before that happens following the parts release. Makes sense if you think about it as they have to purge the stocks of kits with the old parts in or else they would never sell them.

To be fair if you don't have an RB5 at the moment or like me have one with many miles on the clock I'd just buy a new car now and worry about the other stuff later. The Stock RB5-SP2 is still a cracking car and again, it's all in the box!!!

[Aaran]

having more volume in the shock means you can run the shock softer ( a lighter oil and softer spring). so on a very rough surface with big jumps it will ride alot better and provide better dampening. ill admit you wont be able to tell much differance on somthing that rolls in jsut over a kilo, but on a 10kg+ 1/5th going from a 2cmx14cm diamiter shock that would hold about 10cc of oil to a 3cm widex20cm long shocker that will hold almost 45cc made the world of differance!

Saw the Kyosho big bore shocks at my local hobby store. They look awesome and they come in 3 lengths, 30mm, 40mm and 42mm...

Thats my B4 with the Yokomo Big Bores on. Looks soooo porno with my paint scheme and fits on the front without any mods. Just some shims needed between the tower and the shock bushing. At the rear end its quite close but fits...
The car on the left is from Michael Vollmer (Desinger of all the nice Team Durango Cars out there...).

But to be fair... I won both classes (2wd and 4wd) with the normal Yokomo shocks on. Nevertheless afterwards we tried the BB on the B4 and they worked quite well. Depending on the track and the weigth of the car you might need the s, ss or even the sss-springs from Yokomo, as the kit springs are a bit on the firm side. Normally i have the BB installed on my B-Max4 and the ususal Yokomo shocks on the B4.
