i did 130 back in 1990 in my 340 4spd duster. after that it got real scary. to this day i have the same stock suspension ( new bushings of coarse) 4 piston sbp brakes and i've been 9.18@ 147. with no problems. the only thing i'm changing is the disc brakes to the wilwoods just to lighten up the front end and a better wheel selection. my car always stopped good so i never changed them.
