Suspension Upgrade Review
I spent the weekend rebuilding the suspension on my 1965 Mustang Fastback. Below is a list of add-ons/modifications:
Grab-A-Trak 620 Coil Springs
Street or Track Billstein Street Valved Shocks
Opentracker Roller Spring Perches
Street or Track Adjustable Strut Rods
Shelby Drop (used Street or Track template)
Opentracker roller idler arm (steering upgrade)
(I already have a 1" Front sway bar)
Street or Track Billstein Street Valved shocks
Street or Track 4.5 Mid Eye leaf Springs
(I already have traction master bars)
I aligned the car to +5 degrees caster (4.5 on driver side) 1/2 degree of negative camber, and 1/16" toe in.
In limited street driving, the car handles great. Compared to before, it handles like it's on rails. I don't have a lot of body roll and my car tracks significantly better. Mission accomplished. However, these upgrades came at some expense. I can hear everything on the road. From lines in the road, to cracks and bumps. It's noticeable, which I figured it would be despite some peoples insistence that it wouldn't increase road noise. Trust me, it does. However, this isn't my wife's soccer-mobile. It's a performance machine and it's about time it started acting like one. These modifications truly do transform the handling characteristics of the car.
I want to give a shout out to Shaun at Street or Track. He's a good guy who helped me decide on the direction I wanted to go. Also to John at Opentracker. He answered all of the questions I had and was willing to help anywhere he could. I highly recommend the services of these two companies. They're top notch.
I've also got a couple of videos that shows the stock spring perch vs. the roller spring perch. I may post them up to YouTube if anyone is interested. Let me know.
