iTrader: (2)

I have actually had guy's help me out at the track and say lower/raise the roll centre. Adjust camber link for body roll etc.
I just nod and say ok, thanks mate. Walk off and stare at my car with no idea what they really meant.

These vids are great.

Today I raised my rear inner link height by 2mm. It makes the rear end very loose, fish tails and oversteer.

I didn't like that so I put it back to stock. From I have read, this adjustment lowers roll center. Is that correct?

Lowers the RC but reduces camber gain. Tends to give more entry and high speed steering, and more traction on corner exit.

2mm is a huge change. I do 0.5mm at a time

What was it before the 2mm change?

To free up the rear of my car I sometimes add another 1mm. But I think the biggest difference I've ever had front/rear is 1mm

The original height is 0mm, stock.

I will say for the record I am running a front mount motor so any changes in the rear end are probably amplified compared to those in a mid motor mount car.

Yes I understand that 2mm is a huge change. I wanted the change to be glaringly obvious, since I am learning. By my observations it loosens the rear end when exiting the corner.

To be clear, I changed the camber link height, not the arm link height.

I think if I had raised the arm-link height it would have resulted in better on-power traction out of the turns.

In that case you assume they meet at infinity (i.e. very far away), which basically means your RC is as lowest as possible.

How did you manage that, anyway? Arms should be parallel in kit setups.
