You might have an issue with helicoils, but timerserts are solid inserts. I'm fairly certain the frame where the struts bolt to would break before the inserts would. I've also seen some people source longer bolts, and thread them in from the bottom, and then weld them in place (kinda hard since it's aluminum) to form studs that they just thread nuts on to.

You're right the strut mount threads get stripped not the bolt. However they did update the bolt to a torxs. That clunky sound is gone now.

That's how my coilovers are, a nice design. And one of the bolts stripped, it was like 5 bucks for 3 new bolts as you can remove them from the strut and replace them vs. replacing the whole hat.

So if the clunking noise is now gone does that mean you can tell us how you like the monoballs?

I need to put it it through it's paces before I have a well formed opinion on them. First quick impression and very noticeable affect is the steering is very responsive now. I think it will be even sharper once I replace my tires. I had put all seasons that slowed my steering response substantially and the new monoball thrust arms has improved that 100 percent. As for braking I need to flush my fluid. A lot of tracking has boiled my fluids so I can't say yet the improvement there. I already have koni adjustables and eibach street springs, but I did notice that nose dive has improved over what I already have. I don't have my shocks to full tight either when I'm on the streets. Once I replace the brake fluid with RB660 and Firehawk Indy 500 tires, I'll report back with an update.

Like it improves that numb feeling?

Good review so far, seems like it's a legit upgrade. At about 100 mph braking I get a shake, pretty sure it's my bushings. I need to do this.

Numb feeling is definitely improved on. The steering has way more feedback and turn-in on corners is sharp. I don't have my suspension to full tight and have almost balding tires and and it doesn't lean as much and improved the performance of my tires that need to be replaced. 100 percent worth the upgrade. In fact this was as noticeable as my rear sway upgrade. A difference you can feel. Totally worth the money and might as well do your strut mounts while your under there if it hasn't been done in a long time.

Your vibrating can be warped tires, rims, bad bushings. Likely a bad thrust arm as that seems to be the most common on our cars beside rotors and brakes. Can't wait to replace my brake fluid with RB660 I already did the rotors and brakes since I was under there. Once that's done ill report back with braking improvments and then again when I update my tires. Then back to the track Dec 5th Fontana Speedway. Who's in?

Nice thx for the review. This might be a stupid question, but as I was poking around how to remove the thrust arm, I saw I think the monoball kind of attached down in the frame behind a lot of trim. Did you remove all that trim to get that bolt or is there an easier way?

Yes you have to remove the under trey and a few plastic pieces. Easy to do with a 8mm socket.

Ok took the car on a 50 mile road trip. Going freeway speeds and faster across some known choppy sections of the freeway with cornering, and now I can give my honest opinion.

The monoball thrust arms do not get easily upset. They kept my car composed over rough and bumpy sections at high speeds and held very straight lines in the cornering. Even with my suspension at full tight the car has never felt so solid. Like I mentioned, it doesn't get upset easily. I did take it to a speed where I began to feel the limits of the car but it's way up there. I have never drove an M5 but I'm guessing that's how my car now handles potentially better given my numerous other suspension upgrades.

My steering is super responsive, braking has 0 nose dive, rough patches in a straight line or cornering don't throw the car off its line, and it feels like a different/better handling car almost like a new car.

1000 percent worth the upgrade. It's could even be the number 1 upgrade to your car. The handling is next level when pushed or cruising.

It won't pass the California sniff test at smog. I already got flagged and had to go to a California certified smog ref for stored error codes! Some BS. They are way out of control here in Cali. You don't want the smog ref. What a PITA.

My smog guy said they don't do the sniff test anymore (didn't sniff our 2012 last week). Seems they just check for sensor failures.

They do do a visual inspection...

Thanks I got the from a form member here. All of them polished, but now I'm about to sell the strut tower.

Why selling the strut tower bar? Just put mine on a couple weeks ago

[top ramen]

I guess its just you and me with this upgrade at the moment in this forum. Isn't it crazy how just upgraded front bushing changes everything and reduce all the slop in the front. Would love to test the difference since you got mono and I have poly. It's definitely one of the top upgrade you must do on a F10. Thanks for the review.

I have adjustable shocks and and taking off the tower frequently will strip my mounts again.

You could drill a hole through the strut bar mount and have a knob extender stick through. It's what I'm looking to do.

I'm interested in the NVH on both options. I like things firm and connected but I'm not a 21" wheels, suspension-cranked-full-stiff kind of guy.
