So far this forum has been awesome and has not let me down yet! I'm still new to the mod scene, and I did do a quick search around the forum for this but I want to be absolutely sure that I am doing this right as its prob the most expensive part I've bought for my car so far - so please continue being the awesome people you are. Helpful links to similar threads are good too!

2019 Civic Si Coupe
Ultimately, I am looking to get wider (than stock) tires on aftermarket rims for aesthetics but more importantly, more contact on the road. However, I want to avoid rubbing, rolling fenders, etc. at all costs.

That being said, is 18x9.5 +35 with 255/35 with eibach pro lowering springs going to be the tightest fitment I can run without rubbing on an otherwise stock setup? Does anyone have IRL experience with a similar setup? I know it looks great (I've seen a lot of pics) but I want to be sure it doesn't rub.

You all are the best. Thanks in advance!

EDIT: I have looked at fitment industries galleries with similar setups on lowering springs, and most claim no issues, but I am not entirely sure how accurate this is since I have never used them before.

You will be fine as long as you do the front fender tab mod. Just search around the forum and you will find a few photos of it. All you need is a heat gun or hair dryer to warm up the plastic a bit so you can bend it up and fold it out of the way.

I was rubbing the tab on stock Si suspension with this wheel and tire setup. After I lowered the vehicle on Whiteline springs and did the fender tab mod, I haven't rubbed it ever since.

This is close but not exactly what you are looking for
Thank you!
He is definitely close, but he is using the eibach sport which has significantly more lowering than the eibach pro line that im looking to install as well. I mean if he is only dealing with minor modifications then I guess I would be okay, but if anyone out there has the setup im asking about and can confirm, that would be fantastic!

This looks easy enough to do...also surprised to hear you were rubbing with this setup on stock suspension...I read elsewhere that it should be alright to run this on stock...This is why I asked lol thank you!

9.5+35 is probably going to rub if you run anything bigger than a 235, id say do 9.5+ 38-40 and a 255/35r18

With the softer stock suspension it only rubbed on bumps and dips unless I drove over them annoyingly slow.

Also I'm sorry I just realized you said +35 offset. I'm at +38 offset, but I really don't see 3mm changing things drastically. Actual tire widths can vary between different manufacturers, so I'd probably look for a 255 from a brand that stays pretty true to that measurement.

2019 Si models don't have the front bumper screw that the 17-18 models have, so you should be good there. Can gain another ~0.5° of negative camber up front if you pull the strut guide pins. Recommend buying the Wunderladen Strut nut locks if you go this route. Rear camber will naturally go to (-)2-3° with those springs, so should be good in the back also.

If you want to be safe w/o doing fender work, I'd suggest 235/40 tires with those wheels. 255/35 might rub on big dips and/or if you are carrying a full load.

I was on Eibach Pro Kit on my Type r with 265 35 18 with +38 offset had no issue. Had a flush look only rubbed with big dips and 3 other people in the car. Other then that it was nice am currently on swift and its much lower and grab occasionally as well

Thank you! I guess I might have to look into different wheel options or consider not lowering it. 235/40 is what I have on the stocks and I prefer more rubber on the pavement over lowering the car just for looks. Thanks for the tip on the nut locks too!

This is probably going to be the way to go for me then. I care more about getting more tire on the pavement than the aesthetics. Besides, I'm seeing a lot of +40's out there that still look flush too! Thank you!

Hi, have some insight to this as I run a similar setup 18x9.5 +35 with 245/40/18 with eibach prokits on my 2018 Si Coupe.

I had to get my fenders shaved because it was rubbing when going over bumps/dips on the highway when travelling 80mph.


Another thing to note is that I also had to trim the back of the side markers in order for it to not pop out when hitting these bumps/dips.

Here are some pic of my specs.

I run 245/40/18 on a 8'' wheel lowered on eibach sportline and rub some on really big bumps but nothing crazy.
