AC Schnitzer or Dinan or Swift spec-r Springs?

52172 · 12-31-2018, 08:13 PM

Trying to decide. Don't want to lower more than 1" at the most. Won't see much track day but very aggressive street and occasional track days. I'm leaning towards AC Schnitzer as they lower slightly more than Dinan and I believe have slightly higher rates. I like the swift spec-r springs as they are linear and would handle the best, but would have the harshest ride. I will be pairing with Koni sport adjustable schocks/struts. Who has experience with any of these and hopefully have experienced more than one of these? Thanks!

My car is RWD, and I paired the Dinan Springs with the Koni sports about 4 months ago. I don't track the car, but it handles a lot better, and still maintains a stock like comfort ride. This setup gives me more steering feedback on the road. Initially when I had this done, I was running on 19" OEM summer wheels and tires, and I felt it was comfortable for daily driving. Last month, I put on my 18" OEM winter wheels with the 225 45/18 tires. The ride is lot more comfortable, as I don't really feel all the road imperfections. Like you, I was looking for a mild drop, and this setup has worked very well for me.

Thanks. Did you get the supplemental ride kit also? Gives a little added travel?

I did purchase them, but my installer stated they were not needed, since the Koni are already shorter than the stock dampers. They re-used the existing bump stops, since they were still in very good shape. This was all done when my car only had 10K miles on it.

I think he's right for the front, but could have used them in the rear? As they are shorter than the factory bump stops. Would have been pretty expensive for only using 2 of them. I think you could trim the rear stops to get some xtra travel? Probably just fine the way it is?

Yeah I haven't noticed an issue with them. Here is a picture of the drop on my 19" OEM summer setup, as well with the 18" OEM winter setup.

Looks great. Just about the perfect amount of drop if you ask me. I’m waiting to hear the specs on the springs from Dinan and AC Schnitzer.

How many settings do the konis have? Where are they set for everyday driving? What about on full hard do they tighten up a lot?

I pretty much left them in the middle of soft and Firm, and never went back to changing them.

This can probably explain a little more on the adjusting:

I'm going with swift spec-r and konis. It will have the best handling as it's a linear spring. I'll sacrifice a little comfort for handling. Won't need sways later.

You have any updates? Did you get the swift spec-r spring installed?

Can we get a photo of the drop. I'm very interested on this set up. I'm paring swift with koni red.

I ended up going with Fortune Auto coilovers, but you cannot go wrong with spec r and even the red konis I wouldn't think twice
