When I first got this car I thought it was kind of dumb that it had 8 gears because most of the time you can't even get up to the 8th gear. Than after using it a bit and trying other tunes I disliked it even more. Than After quite a few races later and tons of different settings I have found it to be a pretty good car. I smoked the super gt cars and actually won in Sarth against the group C cars (3 laps) and it had that crazy fast Jag in it.
Easy on the gas when cornering and let it coast a bit around the apex than back on the gas.
