If you want to experience one of the Dutch or Belgium tracks in a relaxed but professional atmosphere GP-Elite trackdays are the ones to visit.
GP-Elite has the best instructors, the lowest limit of cars (so always space to drive your own speed) and has everything managed to perfection. You will have the time of your live on one of the Dutch or Belgium circuits on these trackdays.
Intrax collaborated with them and will be present at each trackday to advice the drivers about the setup of their cars (also for the non Intrax shocks drivers of course). So when you visit one of the GP-Elite trackdays and you have set-up questions, just ask the Intrax advisor.
