745s are ok i can see if it were a 545 then i'll be worried get you a fwi and some exhaust mods and then try em. and make sure your fluids are changed if you just got the car. i lol at 745s when i see them and they try jumping in front of me and then you hear whinnnne and see them in the rearview and im slightly modded. but 750s i heard my bf tell me he raced a 650 and i think thats a 4.8 he said he had it by a 1/2 a car all the way up to 130 and dude was pissed lol
