Sounds like a....vibrator
I know that the mazdaspeed 3 suffers from wheel hop problems, but is it that bad? It feels like something is going to break its banging so hard. I think i've made it do it like 6 times in my one year with this car, b/c it dosn't feel right. I dont have the After market Rear Motor Mount yet. I dont have a clue if its normarl for this car to have soo much force as it hops and hits the ground. Can anyone let me know?

I don't know if it's just me or whatever but I never get any wheel hop. I maybe did once when I first got the car but otherwise, I just never get it. I installed the mount inserts anyways for a more positive feel but how are you guys getting wheel hop to happen?
When I launch hard, I am keeping the level adhesion maxed out on the tires or just a hair past it by controlling gas pedal position. Are you guys just dropping the clutch or something?

Wheel hop has a lot to do with dropping the clutch at too high of a RPM.
280ft/tq is a lot of torque for this small car. You go faster if you just slip it at around 2000-2500rpms. I nailed a 2.07 60ft like this on current set-up with street tires. Not trying to brag just offering some advice..

how willing are you to deal with extra vibrations? once you answer that question, we can give you the answer you need.
start from 0 do 1-3 correctly on the stock moutn and u will wheel hop the s*** out of this car....turn your traction off too

not really. i've seen both sides of the fence for extended periods (2 months on CS inserts and a few months on the SU MM), and it's definitely noticeable at idle. the easiest metric for me is when i idle with the AC on at a stoplight: i can visibly see my GPS unit (which sits on a dash mount) vibrating when i'm using the SU MM. it's not bad enough that i feel like i'm driving some kind of dump truck, obviously, but the point is that it really depends on the driver's personal tastes. if you're all about power with refinement, don't get the TRZ mount. what you get really depends on what you value the most.
Okay buddy, obviously you aren't "most people" thanks for pointing that out!
No offense implied but if the vibrations from a SU MM cause you do get upset or something then you might want to check your gender (My opinion)
My point in my pervious statement is that the vibrations are so minor as to not be of worry to most people. If you are an extremely anal person then anything will bother you.

dude, "most people" don't come on forums like we do. "most people" just buy their MS3 and keep it stock. i'm willing to bet that you would be surprised how much "most people" actually do care about the added vibrations from the mount...

if i were upset enough to do something about it, i would have taken my SU MM off long ago. this whole point of my post is that it all depends on the driver, and that is why i asked him in my first post "what do you want?".
Okay and all I pointed out is that the vibrations that result from the SU MM or so minor that it really isn't anything to worry about unless you are extremely anal. What is your point sir?
*Off topic* Anybody here anything on the Cobb AP release??

my point is that your "so minor" and "extremely anal" are completely subjective. you're a modder, so you're obviously willing to make comfort sacrifices. this guy only has a CAI + tints, so the verdict is still out on whether he's willing to put up with added vibrations. our car is marketed as refined performance. hell, every time someone compares us to a SRT4, the very first argument for us is: well, the srt4 may be faster, but the ms3 is so much more refined. shaking the car enough to visibly vibrate a nav unit is going to matter to people who value the "refinement" of our cars.

the AP is releasing this week or next, and Josh@Cobb posted this initial dyno on the other forums:
here's his notes for it:
"This dyno graph has been generated on our AWD Chassis dyno while running the car in AWD mode. We must do this so the traction control system does not take over and re-tune the car. We have spent extensive time trying to smooth out the throttle control, boost control, and torque control systems so this car is more enjoyable to drive. This makes the car easier to drive at part throttle conditions, allows for much smoother part throttle control, and the vehicle acts less like an on/off switch. By doing this we have significantly increased the gas mileage of the vehicle as well with our Stage1 and Stage2 calibrations.
The peak power numbers for these graphs are as follows:
Stock = 247 ft. lb. TQ / 212 WHP
Stage1 + SF = 267 ft. lb. TQ / 222 WHP (20 WTQ, +10WHP)
Stage2 + SF Intake = 279 ft. lb. TQ / 232 WHP” (32WTQ, +20 WHP)"
keep in mind that this was also run on 91 octane gasoline, so once they turn out a 93 octane map + inertial dyno at sea level (cobb's shop is at like 4000ft), it should show some pretty noticeable gains over this graph.

Disappointing. I was expecting more at Stage 1.
Back on topic - I have the Corksport Inserts and have not been happier. I occasionally get a little hop when I pound on it hard, but it is a bounce or 2 then stick, where before it was more like bounce, clunk, bounce, clunk, bounce, clunk, let off, stick. Only drawback is 1 medium-hard vibe at startup, but notice absolutely no additional vibes while running. For me it was important to have comfort along with improved drivability. It is not perfect, but pretty darn close for $35 and change. Just my 2.
When you are speaking about your SU mm are you talking about the 62a or (race) 90a?
62a, I think the 90a would be a little rough for a daily driver..
