I got a 2015 Mazda 3 isport with 101k miles on it and my struts make noise when going over bumps and my rear shocks are starting to leak so I am just wanting to replace it all. I am not trying to spend a lot of money and I don't car if it changes the look or anything. I am just looking for a replacement for the oem parts. Does anyone know if there is a difference between the Godspeed Monss coilovers and the Rev9 Hyperstreet 2 or does anyone have another opionon on a set under 700$

Those are not OEM replacement by any means. Cheap junk, both made in the same factories in China...... If OEM is what you are looking for, just replace the shocks. You can get a decent set for well under $700,,,,

I currently have the Rev9 HSII's, both are made by God Speed. the Rev9 coilovers are ok, nothing great by any means but from my personal experience id stay away from ALL God Speed parts, Rev9 Included.
I've had some God Speed parts and they have failed on me, I always try to do budget builds and do a lot of research and reviews about product before i buy them. The Rev9 coilovers get the job done but I would never buy them again, I cant imagine them lasting very long. I can already feel a difference in the dampening control get
If you're not looking to adjust the ride height or dampening of your car than definitely get OE Replacements.

You should check out this link that list where Coilovers are made

In general alot product from China has had it longevity and performance questioned, especially if you intending to track / autoX or race your car,
then i would stay away from China made, but some higher end products are ok for street every day , but right now all better quality has a price attached to it,
You pay for what you get.
The majority of better /best are made in Taiwan and those made in Japan and Europe, USA made/assembled with have Taiwan/Japan components.

Going from OEM springs / shocks to Coilovers is a big change ... Take a ride in a friend who is on coilovers

When i compared products i often used Fortune Coilovers as a benchmark

Mazda 3 (BM) 2014-2018 - 500 Series Coilovers

CUSTOM. MODULAR. REBUILDABLE. Fortune Auto engineers are consistently chasing improvement and the development of the Generation 8 - 500 series damper is no exception. The 500 Series single adjustable coilover is the entry into the Fortune Auto-verse. Utilizing the highly advanced, High Flow...

I would suggest the Coilovers Im on the Neo Motorsport Type AA ,

But Neo has moved away from one way coilovers to 2 way coilovers.

Both are in the price range as the Fortune ... use it a componet benchmark to compare

And like Arathol mentions ... upgrading the OEM shock to a Bilstein B6 or B8 would be a better product than some of those lower cost Coilovers

You know from all the people i meet at track events and autox (yes it does put more stress on the car than daily driving)
that complain about their suspension is always the same they should have done this or spent more as they know that it will result
in more satisfaction with their car ride. Their goaal being a sporier more resposive , handling car.

But as Mike Kojina mentions it takes some testing to dial in that ride for daily / sporty / everyday
and then know to manipulate that specific track /weather / tires set up
