For sale are a pair of swift springs I used on my previous set of Öhlins Road & Track setup. Specifically, these are shorter 7" springs to move the lower spring perch higher (~19mm) to create additional clearance for wider wheels and tires.

Per usual
Springs are located in Austin TX
Buyer pays shipping/fees (if applicable)

Details
Swift p/n: Z65-178-100
Rate: 10kgf/mm (560lb/in)
Length: 7"
ID 65mm: (2.56")

Please note
Raising the perch while keeping the spring captive requires the lower perch to be at the end of the threads—the only downside is in some instances corner-balancing may be difficult or impossible.
I chose a higher rate, but there was not a significant difference in ride or performance.




Here is an image showing clearance with the swift springs.
Wheel size 18x10 +15
Tire size 275/35-18 Goodyear Supercar 3
Ride-height is a bit lower than Öhlins' suggested height.
