How-To: Stock Height Rally Performance Springs for OEM/B6 style suspension

Thank you for putting this together. I’ve installed 10” 3/2.5” #225/200 springs from FOA on B6 with DNA camber plates. I am coming from 2015 springs with 85k+. Most of suspension components were recently replaced and installed by me with the B6 on OEM springs. DNA arms, spherical bushings & adjustable torsion bar.

With the 10” springs, the car has been lifted about 1/2” in the front & nearly an inch in the rear using crude measurements after the initial install. Very little settling has occurred since but handling is exactly like stock. The noticeable improvements are the initial response and lateral grip. I quite enjoy the way the vehicle transitions & takes compressions with authority now . I have a few track days scheduled this month and will have more to add soon.

Thanks for sharing. Curious, did you take your measurements at the balljoint bolts per the factory spec, or just a relative height measurement. The photo doesn’t look visibly lifted, does it look more obvious in person? I’d be curious how your ride height actually measures out, as there’s a +/- 0.5” tolerance on the factory ride height and I’m not sure why. (Base fiesta ride height spec is much tighter)

The very slight settling I experienced wasn’t obvious until after several thousand miles of driving, as everything seats and compresses.

Just a relative height measurement in my garage from ground to center of the wheel arch at all 4 corners before & after. I couldn’t wrap my head around how to do the factory measuring so I just went with what I know.

In person is a slight lift and the control arms are about 2-3cm from sitting level in the front.

Makes sense. The factory measurement just involves measuring the height from the (flat) ground to the center of the nearest convenient pivot bolt head, then subtract the two

In the front, that’s the front control arm bolt and the balljoint pinch bolt. In the rear it’s the torsion beam pivot bolt and the bolt where the shock lower eye attaches. Not perfect, but convenient reference points that relate directly to suspension geometry without the variability of panel gaps and straightness.

You technically measure both sides front and rear (4 corners) and compare with the spec
