Here's the comparison.
Stock. Turnbuckle touches the spring.
Modded. Turnbuckle is not able to touch the spring.

Looks good will give that a look see since its not impacting the wheel.
69mm driveshafts do come with 2x0.5mm shims for a total of 1mm.
Not true for S3 arms.
When you say Not true for the S3 arms can you elaborate if you mean the 68mm bones don't come with shims or do you mean its not true you can pull the 1mm of shims total and still run a 69mm bone?
What are the handling differences between the 73 and 75mm arms.
Brief explanation from RogerM (thanks!)
The arm length effects the roll centre and more significantly the roll centre migration as the car rolls in the corners.
Shorter rear arms will encourage more tire loading so more grip as the car rolls, great for lower grip surfaces but on high grip surfaces they can stall the rotation mid corner costing corner speed. They can also make the car feel more reactive which is good when a low grip level makes the car feel less reactive so making it harder to place in technical sections.
Long rear arms the opposite, car will rotate more freely for more corner speed but won't generate as much side-bite so mid/late corner will be reduced. Make the car feel naturally lazier which is great on high grip surfaces as it makes the car easier to drive overall.
So the long Vs short rear arm is just like the flat Vs gullwing front arm, all about the grip level from the surface and how technical the track layout is.
Is this basically what is being described here:
SF2 rear hubs do narrow rear width a lot. probably needs some different driveshafts or axles. Is your car lacking something?
More so just looking at comparison between narrow a-arm usage versus narrow hubs.
