Quick question about strut tower mushrooming

I want to prevent it.. so I was gonna get the reinforcement plates from turner. But I also want to get an ecs tuning strut bar..

So my question is.. would a strut bar act as reinforcement too? And if not could I use the reinforcemnet plates in addition to the strut bar somehow? Thanks!

What makes you think your strut towers will mushroom if it hasn't happened already?

If you have stock suspension, there really isnt any reason your strut towers will mushroom.
Mushroom is a result of people being stupid with their suspension and/or driving like a-hole on really crappy surfaces.

There is really no reason to have suspension that is so hard, that it feels like there isn't any suspension at all. This means that instead of having your suspension work, you're really transferring the suspension load to the car frame, which equals mushroomed strut towers.

A strut tower bar's job is to keep your front end geometry from pushing inward from either side. Every car frame has some flex in it, a strut tower bar's job is to eliminate some of the effects of the flexing up front.

Its a zsp suspension.. I know its a little tighter than normal.. but still basically stock.

I know what a strut bars job is... I was just asking if it would also act as tower reinforcement too. I'm not sure I got a straight answer but ill reread your post (I'm on my phone)

I mean.. I'm going to be smart with my driving though.. like not pushing it beyond what it can handle. I'm just doing what I can to ensure a long life for my car.

ZSP suspension is still stock.
The strut tower bar will not, or do little to help prevent strut tower mushrooming.

Alright cool.. cheers.

I like how my suspension feels so I don't guess I need a strut bar..

Ill still consider the plates since they're only like 22$ though.

Do you know that the struts have to be removed or lowered to install the plates?

No.. I was going to look up installation for them though. It looked like the just bolted on top but I wondered if they went under (which makes more sense..)

They do not need to be removed, but they do install under. I mean you can loosen those 3 small nuts on the top with the wheels in the air and manage this job, I have the BMW plates, also bought from Turner. For some reason they only charged me $5 ea, or $10 for the pair.

They go under the shock tower. You'll need an alignment afterwards since when you loosen the top 3 nuts you'll throw off the front camber.
