Default Installed Megan racing RCAs

Like the title states. Not bad for 70 bucks shipped. I have driven the car pretty hard over the weekend and nothing concerning yet. Let's see how they hold up. I'm not worried about the caster angle as I haven't felt the car behave any different nor do I plan on tracking it. The drop is perfect with the oem 08 suspension. No scraping or rubbing.

Noob question, what do those things do?

Your paint looks great by the way!

Thanks! It looks like crap in person! Rock chip and swirl galore

The RCAs are supposed to correct the angle of your control arms ( Roll Center Adjusters) when dropped
On the factory shocks you are basically moving the hub upward while your shocks and control arms stay the same. So it reduces wheel gap in turn dropping the car.

Here's a detailed write up about the install so you can see visually

Thanks, I had read the thread you linked before... Just wasn't sure what those bushings were. Hope this works out for you!
