Default 2015+ WRX Mach V Springs

This is my review of the 2015+ WRX Mach V springs. I’m making this review to help anybody who is looking for a good quality spring with a mild drop that does not sacrifice ride quality. Before installing these springs, I was using the Swift Spec R springs. Below are the spring rates to compare and will give an understanding of why I may review these springs the way I do. Sorry for the low quality cell picture but it gives an idea of how these will sit initially.

Spring rates:
Stock: 324F/291R - 0 Drop
Swift Spec R: 335F/402R - 1in Drop
Mach V: 360F/310R - 3/4in Drop

Initial impressions:
When I first got the car back and started driving, it was a relief. With the Spec R springs, it was a little rough with all kinds of bumps and imperfections on the road. I would feel all kinds of jolting and bouncing. I thought they would get better after settling but they did not. After a few months, I did not enjoy the ride and neither did my girlfriend. I began looking for something a little softer for these Jersey roads. I looked at RCE blacks and yellows for a while and researched as much as I could on whether they would be better or I would just be feeling the same harshness. Then I began looking into the Mach V springs. There’s not much as far as user reviews on them but Mach V has provided a thread on some of their products and there’s a little info on these springs. I decided to pull the trigger of them and I could not be happier at this point. These springs are definitely quieter than the ones I had before. The harshness is reduced significantly. I would say these are fairly similar to stock feeling on the road. As far as the ride drop it still has a nice mild drop compared to the Swifts as seen in the pictures above. I will update more on the ride if anything changes to the drop or harshness. Again, I cannot speak enough to how impressed I am with these springs on stock struts. I would strongly consider Mach V if you’re in the market for more springs.

As far as a little update on these springs, short story is I will have to get rid of them due to my stock shocks. After a couple of weeks, I began hearing clunking and small popping that was getting worse and worse. I brought it in to a Subaru dealer to have them take a look and the mechanic showed me that my fronts are leaking and the sounds are from the struts failing. He checked the integrity of other comments like the sway bars and the strut assembly to make sure nothing was loose or broken there so it’s the strut going bad. Because I only had these springs on for such a short amount of time, I wouldn’t blame these ones for the problems but possibly the older springs that were on. For the short time the struts were decent, the ride was still very comfortable and I was happy with the purchase.
