Nothing really just an accurate setting fit n leave if u need to change unscrew re screw!
X-rays defiantly work u can see that by how many cars they had in the a mains of the worlds just gone..... Oh none!

Yes lots of factors were against ALL teams mainly weather but every driver had the same opportunity.

I loved my xray's I loved the fact of a new car each year, after a years running they wear, plus the novelty factor of the newest car.

I've come away from xray for the fact of the pivot block design simple yes it works shimmed properly I ask should this need to be done? No my TCXX bolted together perfect, no undoing the screws to set perfect

Xray is a great manufacture very stronge and is quality out the box so please don't take this reply in the wrong way.
