These Stiff Rings instantly made a difference on how the car feels, I have them installed along with some other mods and the car handles much better.

Is it a pain to install under the car? Any special tools or technique needed?

Thanks Jason. We have received nothing but great results from our customers on these since we've been selling them.

Not really, much easier to install with a lift, however it can be done without one. You can find MDJammins DIY on the forum here:

Hey all! Ride feels a lot sturdier than before and I believe these little things are worth it. Definitely apply some wd-40 when tightening because probably they've never been taken out so tightening can be a struggle for some of them. Also, it is advised to use an impact to take them out because we had a heck of a time getting them off. However installation was easy and make sure to read the instructions on tightening by hand. In sure in between it's possible to tighten with a power tool but only to a point and finish by hand. Here are pics of locations for the subframe. Also, highly advise a lift because taking them off when you're on the ground and having no leverage makes it nearly impossible. All in all a great buy and much more of an impact for our vehicles compared to a strut bar.

Awesome review Owen. Thank you for taking the time to write this. No pictures were posted though. I know you said here are the pictures and locations. Very happy to hear that you notice an impact with these installed.

Just seeing your post now. Can you send me them again so I can post them? You can also load them using Imgur and paste the BBCode here.

Awesome product, really is a night and day difference! Note: I believe it's the 14's or Lx, don't use all collars.its 6 up front and 6 in the rear.

Thank you, we think so too. It's pretty impressive what these small little pieces can do overall on the way the car feels.

You know I have come across a few models that don't use all 8 pieces in the rear, not sure what the determining factor on that is TBH.

Some of the rear sub-frame assemblies (my 2011) are held in pace by 4 bolts whereas others are held in place by 2 bolts and two studs w/nuts (my 2013) meaning you would have to remove the sub-frame completely to install the last 2 rings.
