What is the details of your kit? I wonder if it is the same as they did for mine?
They made yours in 1 month? Took them almost a year to come up with something that didn't fit for me.
I can comment on track use. They were fine for the first 5 days. The steering wheel shudders now something cronic under hard braking.
