I wonder if 20mm spacers may ruin my suspension. What is your opinion?


PS. Its going to be my second mod after Stillen CAI. I've got some doubts so need advice.

Spacers do have adverse effects on some suspension components but they are relatively minor. Unless you get an insanely thick spacer, it won't ruin anything. Lots of people use them and very few have any issues.
 
20mm is a good spacer without any rubadub on the wells with a stock rim. 25 would be the max.
You should be fine & wont harm any components as long as they're installed properly.

Rubadub being a suspension industry term.....? :)

Go 25 in the front and 20 in the rear, I regret not doing it on mine. I read the suggestion in a thread took note of it and then went with 20's all around. I still feel like the fronts tuck in a hair too much.....

Really? I thought it was the other way around...i.e. the rears tucked in more than the fronts...It's been a while since I measured with my summer tires on, I'm likely in error.

Logan's right. The fronts do tuck in a bit more then the rear due the the front fenders are flared out more.

Thanks for replay. Another issue - will 20mm fit 275/45/20 tires?

I have read a lot on the forum about spacers. I do have a couple of questions.
I believe the wheels on the FX are hub-centric, essentially the weight of the vehicle is supported by the hub, as opposed to the wheel studs.
If the wheels are hub-centric are the spacers hub-centric also?
 
Not all are hubcentric . The safe way to go with these are H&R regular hubcentric ( no studs installed , just seperate studs that come with the kit ) part # 4065662 , 20mm , times 4 for all 4 wheels. Some members differ on the stagger of the spacers, wanting 25mm for the backs and 20mm for fronts .
 
Personally , I do not like changing to longer studs for many reasons , I like the integrated stud , hubcentric spacers from Ichiba , TCSportline etc. they are way easier to install and I feel that putting a longer stud in with a spacer puts more stress on the stud.

You're right, but the studs are engineered with what's called a SWL or Safe Working Load, which is usually in the neighborhood of 300% of the total load bearing capacity of the item in question. That means if each stud needs to withstand 500lbs in shear to hold your wheel on under "normal driving conditions", they are actually built to withstand 1500lbs so that they dont fail if you happen to veer outside "normal driving conditions". Reputable companies (like H&R) take this into consideration and account for it.

Technically speaking, the only issue with running spacers is a slightly reduced service life of some of the suspension components. Exactly how much of an impact this has is pretty subjective though, and most people don't even consider it to be an issue.
 
While I am sure that the maufacturers have done their homework on this , I still prefer the spacers with integrated studs and have used them extensively on many cars , they are also way more convenient.

Some time ago I purchased a set of Rondal wheels for my 1978 Jaguar XJS. The wheels had a standard off-set and they were mated to specific vehicles offsets via hubcentric adapters (spacers). Depending on the width of the adapter, they came with the required longer wheel nuts.:rolleyes:
