just how free is the drive train meant to be, on the car my son has a mi4 and there is no friction all most at all, yet my car seem's to have a fair bit more, it is very smooth just a bit stiff i think, can anyone one think of what is making this happen or is this normal for the car.

Roll centre
Hi,.. guys,..
I am confused here with regards to roll centre.
In the front & rear arm mount, my understanding is ...
- for low grip surface (low traction) - roll centre should be set low (can go as low as 0A in arm mount), so that we can get grip.
- for high grip surface (high traction) - roll centre should be set high (can go as high as 3B in arm mount)
This is clearly stated in TC6 manual, which I quote:
"In general, lower roll centres will effectively make the care softer in roll, allowing the car to lean more in corners.
Lower roll centre positions are good for low traction condition.
If the grip level is high, then raising the roll centre to a higher position will help to stiffen the car in roll making it more stable."
From another internet source with regards to roll centre, which I quote from:
"The suspension mounts offer a lot more in the roll center adjustability. By running a lower roll center, pins closer to the chassis, you will gain more roll in your chassis, which results in less use of the tire. By running a higher roll center, pins higher, you have a car that now drives flatter and places more of a load on the tire for traction. Generally speaking, a lower roll center will have less traction where a higher roll center has more traction. You can easily see this with foam tires, a place where we never use high roll center since it will make the car traction roll due to the increased traction capabilities of the higher roll centers."
Now,... which is correct????

Can anyone explain the pros and cons of spacing the front and rear wishbone/arm carriers against the chassis, eg. if the front wishbone mount has a 2mm spacer at the front mount and the rear mount of the same arm has 1mm that is making the outer axle pin carry the C hub with a toe out attitude.
Why do this??

My understanding is a lower roll centre allows more roll, more pressure on the tyres and hence more grip.......useful in low grip conditions. Conversely, a higher roll centre generates less roll, less pressure on the tyres and is better for high grip.

Lowering the roll center increases the moment arm length between the roll center and the CG. This will make the car 'want' to roll more since you are not changing the total weight transfer at all. You can reduce the total roll angle via springs and anti-roll bars. In general, a lower roll center will increase grip.

Ok guys I need some help. I picked up a TC6 and I need to get to a final drive of 4.0. What spur and pinion will fit to get me where I need to be.
Thanks for the help,
Joe

i use a 64p 100 spur 50 pinion that give you 4.0 it would give you good high speed and good torque.
