Wheel Spacers with Coilovers Question

I have OEM 162 Wheels on my E90. I am will be putting on FK Konigsport Coilovers.

I've been told I need at least 3mm spacers up front to clear the wheel from strut tower. Some tell me that, according to my wheels (ET 34 font), I do not need any.

Can anyone confirm this?

3mm!

Even if you found a "fester' with the same wheel and coilover, you should be aware that your tire brand choice may very well make up for the difference. There could easily be a 3mm difference just due to the tires as each tire manufacturer may differ in "overall width" for the same size designation. If a 'new' tire is THAT close to the coil over...you should be aware that a tire's overall width will grow (casing stretch) when inflated after about 48 hrs., at least 1 - 1.5mm.

You're going to need a test fitment with the tires of your choice.

If I can get away with doing spacers, I would very much like to do so.

I don't need spacers with my H&R coilovers. Wheels are et 33 I think.

So with my et 34, you guess I can get away without spacers?

Style 162, 18"x8.5", 235 series front tire.

With stock strut tower, I can barely fit two fingers in the gap between the inner tire wall and strut tower.

I'm really not sure to be honest. I never really got into learning what the offset of a wheel is. I just learned what the numbers for tire sizes mean.

I was just posting as a reference.

Actual overall tire width can vary more than 3mm between tire manufacturers.

Since not many solid answers, I took these shots.

They are going on next week. What do you guys think about the requirement of spacers?







I am guessing, since I am only going slightly lower than sport height, springs would end above the tire?

Konigsport Coilovers, OEM 162 wheels.

You really should not need a spacer for those. But, a set of 5-8mm spacers won't be more than $75 or so.

May I question your logic on this? (Sorry, I am trying to be rude, it's just I REALLY want to NOT do spacers, but after installation, If I need them, it will take at least 2 days to get the correct ones for $70-$90 that don't want to spend)

1. If you look closely, I got less than 20mm clearance between tire and stock strut tower.
2. Smaller, helper spring sticks out at least 17cm and the big spring sticks out even further.
3. Even if I go with the tallest height, springs would come past tire, unlike stock strut.
4. When the weight of the car comes down, helper spring would compress all the way.

I think you're measuring clearance in the wrong location - where is the swaybar end linkage with respect to the clearance point? Are you planning on using the full lowering potential (as the current setup shows)?

Swaybar end link mount is on the opposite side of the tower. All I need to do is clear the wheel at that point as in that first photo. Thickness of the strut tower is the same on stock and coil overs since they both have to slide in to the same size socket.

Don't mind the thread height, that was how the coilovers were shipped.

If your measured location is directly opposite the sway bar end linkage position, then the lower spring perch of the coilover setup will always be higher along the post than your measured location unless you fully bottom / fully lower the car.

That's true. However, I believe the swaybar mount is actually lower on these coilovers compared to stock.

Definitely shouldn't be - all sorts of interesting problems can result. Admittedly, things will change once you start lowering from the stock position, but the linkage should be in nearly the same place at 'nominal' ride height.

That being said, even 3mm clearance is pretty decent - nearly an 1/8". As long as you're not going full drop I'd be willing to bet a dozen donuts that you won't need spacers.
