Only question is was your friends car stock or upgraded arms cause i felt huge difference with upgraded arms, just two days ago i was running my friends triumph 600 and a car pulled into left lane at 70 while i was doing 160 around a light curve on a normally safe very high speed rd "traffic is usually 90 to 100 off peak". I gained prob 15 degrees of yaw thought i was going to shoot off rd or have to rear end car but i waited a sec before trying to counter steer and the car settled into slight brake induced oversteer and then slowly got back in shape. point is i have my car perfectly nuetral with slight toe in front and rear and all upgraded suspension bushings 440f 700r and is extremely stable i think it might be worth shot trying little less toe out in front and little less toe in rear to keep your oversteer and add stabilty. Also you could reduce rear camber a little or maybe add little rear bar i just have never had good experience with more than 0 toe in front on any car ive driven. Ymmv but just my 2 cents.
