What we’ve done here is pull a spring out and check the wheel/tyre clearance to the chassis at full bump. Even though this car has a mild set up in terms of tyre size and wheel offset, as you can see in the first video the tyre can still contact the chassis. This is undesirable because it can create handling issues. Variables that contribute to this situation include, larger diameter wheel/tyre set ups, low offset wheels and anything that modifies the shock body position. Spend an afternoon checking your set up and if required fit a set of our Bumpstop spacers
