*BY ADOPTING THIS TUNE, YOU AS THE THIRD PARTY HAVE READ THE DISCLAIMER ON THE FIRST POST AND HAVE UNDERSTOOD ITS CONTENTS*
One of the more expensive purchases currently in my garage. I usually don't buy my cars but rather win them through B-spec, but this I bought because of the German Touring Car Championship on A-spec Extreme. Frankly speaking, this is one bloody good car. I raced it right out of the dealers without ANY modification and managed to come on top in the races, albeit some close rivalry - but that's what racing is about. Anyhow, Avid has transformed this car into something even more spectacular.
First impressions of the car was its tendency to over-steer on exit, and some noticeable under-steer on mid-corner. Turn in is good but not as sharp as I would have expected, but nevertheless it is one of the better cars I was impressed with without after market modifications. Looking at the replays and telemetry, I observed that the car's weight did meant the car suffered some body roll (though not much), this translated to loss of grip on the inside tires thus losing grip while coasting through undulated bends. This was rectified by replacing the stock anti-roll bars for stronger ones and also lowering the car's height for a lower centre of gravity, resulting in less weight transfer. The springs rates were also stiffened by around 20% so there's less slide. The stock damper configuration was good, but some tuning saw slight decrease in the front compression rate to allow better entry.
The car's tendency to over-steer was quickly remedied by tweaking the LSD by lowering the acceleration sensitivity, yet increasing the initial torque by roughly 60%. Deceleration sensitivity was also slightly dropped for better coasting. The overall effect meant the car was less prone to snap-steer, yet retaining its cornering ability.
Lastly, down force on the front and rear were both increased with a front bias to promote hard acceleration through bends. Furthermore, the increase in down force also helps decrease braking distance.

Am I missing something? I did what you said, purchased the car, stage 3 turbo but the power is still at 650hp, with the stage 3 engine upgrade it would get to the power you mention but as that isn't a requirement I'm confused...
