Yes i understand completely
the diffence it makes on a road car with an already strong designed box is miniscule
I just drive like a normal person. With a dab of oppo.
Iv been out today trying to get the hang of this.... Keep putting to many revs this ent easy!!!
You need to nail rev matched downshifts without breaking before even trying it tbh.
I also find the trainers i'm wearing at the time makes a big difference to how easy/hard it is to do.
