How did the Ohlins Spring rates compare vs Swift springs? What made you use the Swift springs?

Thanks
It is just dirty in the picture, this weekend when I am back home I'll clean them a bit and post better pics.

I ran the Swift springs for two reasons:
1. A higher spring rate many complained the stock Ohlins Springs were too soft, I never installed them so I cant provide much guidance there. The rates I selected are commonly run, recommended to me when I bought these new and you can go a little stiffer if you need to especially running a R-Compound tire.

I believe the Ohlins rates are as follows:
Front: 400 lb/in (70N/mm) - Swift is 336 so a little less in front, but a shorter spring
Rear: 343 lb/in (60N/mm) -Swift is 672


2. The Swift Springs are shorter which allowed the spring perch to sit above the tire allowing a wider tire up front.

Hope that helps.
