Hi Frenchy , I run with CSP Disc's , 2 1/2" dropped spindles and a 3 1/2" narrowed beam with Sway A Way's to accommodate my 5.5 Flat4 BRM's
I only took out 3 1/2" coz I wanted it to look as stock as pos but have no rubbing issue's , mission accomplished , only thing I will say is that the ride is a bit harsher due to the shortness of the springs "not enough length for a bit of spring twist I guess" .
The CSP's pull up great with no wheel locking " something I suffered with the my old wheel disc combo " porsche patten vw disc's " ,
I've also upped the braking out back with T3 drums which along with the CSP's pull the car up real nice
