Default Long or Short Rear Shock Ball

Hi,

I had my first race meet (I didnt race fully as I broke in the motor on the track). I guy checked out my RRR and said the following:

- The ball end of the rear shocks were incorrect, I had to use the long ones but when I came home and checked out he manual it states to use the shorts ones. Is this correct? What is the difference between the long and short shock ends? Does it effect handling?

- I was told to change the rear shock ends (the ones that holds the steering knuckle onto the chassis) to the longs ones instead of the short as this will make the suspesion arms flat rather than on an angle as this will help rear end stabilty - is this the case? I know the angle of the arms effect roll centre??

If you are new to the RRR/WCE, you may want to race your car stock for a while and slowly try different things based on what you think your requirements are. Some people have very little or no upgrades at all, while some upgrade everything. Some of the upgrades may compensate for deficiencies in your setup, driving or tuning - or give you more tuning options, but they are not magic bullets.

The thread I initially started on the "Ultimate Edition" has some really interesting exchanges. If you have the time, you should read through it.

If you haven't already done so, read the first few pages in the published specification. I think it will also give you some things to think about.

Hi, a very nice catalogue to introduce the parts of V-One RRR UE!

I am new for driving V-One RRR and I found that my drive belt is not smooth enough, any ideas?

Another question is whether someone heard about the materials of brake arm other than alloy?

- Which belt or all 3?
- Do you have the belts set at loose or tight? Loose is best.
- Have you tried removing the middle belt? Is the front or rear still not smooth?

If you just built the car, everything might be a little tight. After a tank of fuel, everything should loosen up a bit.

Thank you!

That means the looser belt causes the smooth belt motion, doesn't it?

Since I have tried some others cars' longest belt that they are very smooth as the belt moves about 3cm more after applying some force on the belt. I don't know which belt(s) are tight. They are all in standard setting (tightness).

But now, it stops revolutions instantaneously after applying some force on the belt.

Sounds like something is jammed. Take off the middle belt and turn the front wheels and rear wheels. Is it the front or rear that stops turning??

The force is just applied by hand, would it not to be turned if something is jammed?

The front one seems to have a bit inertia, is it normal for a new car?

But for the rear, there are no any inertia happened........ the Rear gear box can be turned by a little force.

There are 4 positions for the front and 6 for the rear for belt tightness. Which one should I set to when the car is new? Thanks.

When you filled the rear diff with oil, did you fill it past the top of the bevel shafts? That can cause the rear to be too tight. You should only fill it to the top of the shafts.

Thanks! But why the diff. oil level will affect the tightness of the rear part? It doesn't only affect the smoothness of the gear box output, i.e. left cup joint and right cup joint?

I am sorry to make you confused. In fact, I would like to ask whether there are any methods to let the belts go smoother.

If all of your belts are loose and you roll the car, it should move freely. If it does not, something is wrong. Make sure you installed the eccentrics (sp?) correctly. If they are correct and it still has resistance I would remove all of the belts and spin each item individually until you find the problem.

That is the same thing I was thinking as Jag. The other thing is all of the belts are loose then you may want to check the bearings in those areas. One may be bad or it is not properly seated in it's position. Just a thought. Hope you find out what is causing it.
