i would say if you run on rubber tire, a less stiff chassis is preferred but on foam tire, a more rigid chassis is more on what you need/

I just fitted my one way and find that smaller tyres at the front gives the better handeling, difference of 2mm.

Problem is i end up with larger tyres at the front than the rear as the rears wear quicker.

I wanted to fit a different pully on the middle belt to give the same effect but which one do i change? I have 18-27 at the moment.

The K factory sells a 19 teeth but this will have the opposite effect of what I want I can also get a 26 tooth one but this also speeds up the fron wheels.

Am i missing something?

you should have 19/27 instead of 18/27 check your other pulley and see if you have mis install them.

you may change from 19/27 to 19/25 and with kyosho SP belt with length 375mm. you may be able to do it with larger tire split (4mm).

for the 25T pulley, kyosho has a pulley set for VoneRR and you may get all the pulley you want there.

download the overdrive ratio tool here to check on your OD ratio and tire split

Nice little app to see the drive ratio! Whats the teeth on the diff pulleys for the v1rr?

The front should be 32 and rear 48

Manticore

it is not my app. it is Dino's appl.

Ok i counted them. 32 at the front and 48 at the rear. So with 18-27 pulleys installed you get 1-1 internal drive ratio front to rear.

This will allow me to use only a 1mm smaller front tyre

The way I see it is that if your running foam tyres and a front one way you get power on to the rear wheels along the straight, effectively 2 wheel drive then as you turn the inner front wheel is rotating slower than the outer front wheel and so the power is applied to this and helps pull you around the corner.

This sound OK but why would you want overdrive to the front wheels when running rubber tyres? My car handles like a pig with front overdrive on foams!!

Manticore

you cannot trim rubber tire size so you better stick with 27T pulley.

I am using foams

Tell Dino that Plley is spelt Pulley!! LOL

Manticore

you should send him a complaint, you are his potential customer ! hahaha

Do i have to change the middle belt if I go from 19 to 18 tooth pulley? Can i use the Kfactory one K1404 Low Friction Belt

Ooooopppppsssss....

thanks.....

Why would you say this?

I'd be thinking a "bendy" chassis would essentially act as part of the suspension and therefore be unpredictable.
