ND1 - Stiffest Spring Appropriate for Club Bilsteins

On track the other weekend I finally hit the point where I’m frustrated enough with the car’s floppy factory setup to actually do something about it. I already have a set of the Progress sways ready to go on the car, but I wanted to pair them with some stiffer springs as well.

I’ve seen quite a lot of people worried about maintaining nice street manners with their spring choice, but I want to go in exactly the opposite direction. What is the most aggressive spring I can run on the factory Bilsteins? The Progress springs certainly seem to be a very popular choice, but would the Swift Spec-Rs be a better choice for a non-daily driver that does more track days than street driving?

The car is a 2017, which I read has more damping from the factory then the 2018+, not sure if it is enough of a difference to be relevant.

That's easy and the answer is on the site.....see RoadsterSport spring product description. Swift is not bad at all, but still less rate (SLOWER) than RoadsterSport Springs that are 300 lb/ft front and 200 rear.

Thanks! Somehow I completely overlooked those, seems like pairing them with the performance bump stops should get me exactly what I’m looking for!
