First of, when I first bought my 417, the rear came with XA-E blocks, which I ran at a medium-high grip carpet track for about 2 month until a fast driver told me to swap to 1X-1F blocks in the rear. This resulted in a slightly wider rear width but with the same toe in as before. And since then, I have kept the 1X-1F blocks and I was wondering if I should consider getting new blocks or going back to the old blocks. (I Now run on a lower grip/tighter carpet track compared to before.)
What is the effect of the rear blocks/rear width please ?

And finally, does anyone have a clear explanation with the physics explained between different suspension blocks. (Such as B, D, C blocks and so on.)
What do they do ?
What I don't get is that even if people change their suspension blocks, they would compensate the toe change with the toe links. So whats the point of changing the inboard toe blocks ?

Thanks alot

What effect did you find going to the XC and C block in the rear of the car? I have liked B blocks on the front of my car, what would changing the rear to XC and C do?
