Advice for BMW M3?

[Ripper_Rabbit]

I have the 2008 BMW M3, it has the speed but not the handling. It's completely modded. Any advice?

Can't tell you how to fix it if we don't know what's wrong with it.

I have a tune for the car but it's not meant for full power upgrades but if you want to give it a try here you go...https://www.gtplanet.net/forum/showthread.php?t=137161

It may be an M3, but it's still pretty heavy. That could be why cornering grip is a bit weak.
