Changes top-view reaction point between tires and chassis, so it can give more or less steering depending on which direction of sweep.

Helps explain why inboard toe and hub toe have different effects in rear.

I put this down to the gear diffs. The Diffs have no give (unlike the ball diffs).
The drive line unloads (forwhatever reason) then grips, this shock, that used to be absorbed by the ball diff is now taken by the belt... which only stretches so far...

Yeh thanks mark, having snapped 2 in the bottom notch and 1 looser I'll try tighter and I'll see how long that will last, just need spares in case.
Thanks

Hi Marek,

The belt napping is probably related as much to driving technique as it is setup. I've not managed to snap a belt since September, racing is similar high grip environments and just being careful with throttle applications.

What sort of motor/track conditions do you race in?

hey guys,

I also finished my new t3 '12 last week, now everything is setup but didn't have a chance to test the car yet. However the parts quality is awesome and booklet is clear, I really liked it.

I have only one question, the rear small AL. bulks which gives the toe in.. During the assambly of it when I screwed these small bulks, I recognized that they move a little which changes the rear toe angle..After the assambly I found out that the rear right toe in is 3mm and rear left toe in is 2.5mm ..I am sure that I assambled everything correct way double checked already.. There is some variation I guess, have you guys seen such issue or is it normal?

Many thanks in advance.

I have seen this on mine.
I cheated and just put the right shims in each side to get what I wanted, not what the manual say's .
Now have perfect 3deg each side lol

Did you check this with setup wheels and a ruler? If you search youtube you can see Collari pointing out a minor imperfection in the HUDY setup system which gives an inaccurate reading of toe-in. I have heard other top drivers state the same.

Just my two cents.

They flex less, which is most cases will take away some traction. They are also prone to bending, which usually isn't noticeable and can cause erratic handling.

Xray plastic is so durable I don't see any need to change out any of the plastic in the car (not even the shock bodies).

Can't find the video you mentioned.

I also found the problem with the rear toe using Integy's system which I had before.
