I have issue. I inserted custom cars to my server and changed handling for everyone. I have Audi R8 in my custom vehicle and I set for him 7 gears, he comes at 250km/h in third gear and have like motor blockade, you need to drive him another like mile to unlock speed to 300km/h or above. Any idea how to have faster changing gears?
Hi there,
you will have to consult a vehicle scripter to assist you. Most of them unfortunatly won’t do it for free.
Good luck

A lot of it is just playing around with numbers but having a description of what they do helps.
@scottdl What was even the point of your response? To get that extra post in and advertise?
Not at all, the point of the response was trying to inform his. @termanator1128
