I hv an experience my evo got burnt smell after heavy rev (actually like sprint test laa). I guess the smell came from clutch as the source is somewhere between gearbox and engine. It happened at night...
I currently changed to toyo T1R, i m satisfied with its gripping output.... reason i change to it is because the "suku" normal sime astar 300 tyres cant hold my car power, during mivec on, tyres burn and feel bit...
