Update on EPIC Engineering prototype springs for 08-09 STI
After a few production hiccups, we finally received the new rear prototype EPIC Engineering springs and bumpstops, and installed them onto our 08 STI. I’ve been driving the car all this week for my commute and despite the rear being just a little bit lower than previously, there hasn’t been many noticeable handling differences. Here’s how it sits now:
The ride is still extremely smooth and comfortable, in fact even more comfortable than previously when going over expansion joints on the freeway. Dan made a few adjustments to account for the little bit of oscillation he was experiencing with it when he test drove the car for a few weeks. He also put the car through its paces, testing different driving scenarios (such as free on/offramps, fast emergency lane changes, and uneven/pothole-ridden roads) to ensure the springs were doing exactly as he specified. I think with these latest changes, full production on these springs will likely be starting soon, but that’s Dan’s final call of course. Either way, I’m still beaming happy with them and I can’t wait to start selling them to fellow 08+ STI owners!
