245/35/19 9x19 et 37 and 275/30/19 9.5x19 et 28

purity · 07-28-2006, 12:47 PM

Hi everybody,

I am ordering wheel for E90 lowered with Eibach Pro Kit already.

The Front wheel size is 9x19 with et 37
I am planning to use 5mm spacer,otherwise it might hit/rub the front strut.Do you think this is the correct spacer size or should I go 10mm spacer?

Then for the front tyres I am still can not decide whether to use the 245/35/19 or more conservative 235/35/19
Anybody can help me decide please ?

For the rear wheel size is 9,5x19 with et28
I hope this do not create problem,
and I am planning to use 275/30/19 tyres.
anybody have experience with this offset and tyres size?

Thank you

You might want to be careful using a 5mm spacer. I don't believe the 5mm spacers are hubcentric. Not sure what the best solution for the front wheel would be though.

thekewl1 · 07-28-2006, 01:23 PM

your front setup is pretty aggressive because of the 9" width. I'm running 19x8.5 w/ 35mm offset on the front and it sits pretty flush with the front fender. u should probably try it first w/o the spacers and if u are rubbing on the strut then add the 5mm spacers afterwards. 10mm spacers in the front might rub on the fender. Since your car is lowered and given the aggressive front offset u should probably get the 235/35/19 tires for the front.

your rear offsets should work. I'm running 19x9.5 22mm offset w/ZSP and 265/30/19 and no rubbing right now. I'm debating the Eibach Pro-Kit, since it is the most conservative drop for my setup, but even with these, I may rub. Since your car is lowered u may opt for the 265/30/19 tires just in case. IMO 275/30/19 will probably rub on the fender but that's just a guess. Your rear setup will be about 1/4 inch more tucked behind the fender than mine, but I'm not sure if 1/4 in will make much difference.

ya, that's the other thing, u have to be careful when using spacers. That's why I got a setup that did not require spacers.

whats your setup?? any spring and strut?

current setup:

Sport PKG
F 19x8.5 35mm 235/35/19
R 19x9.5 22mm 265/30/19 (aggressive, I love it!)
Tires: Toyo T1R

No rubbing at all right now. Needs to be lowered ever so slightly. I'm considering the Eibach Pro-kit. From the info I found on this forum, it will give me an overall drop of 1.2" F and 1.0" R. Since the SP already lowers the car .6" all around. It will lower my car an additional .6" F and .4" R. I did some measurements and I think I can clear the rear fender well with the Eibachs, but it's pretty close. If you want to be safe get a 25-28 offset in the rear with 265/30/19.

My problem: My driveway goes underground and is pretty steep. I have the breyton front lip and sideskirts on order so I need to see if I can still get into my driveway with the kit. I'm not sure how low the sideskirt and lip will extend so I'm holding out the springs till I find out.

Thanks for the suggestion Ghunger and thekewl1,
My question for thekewl1 is, do you roll your rear fender and front fender?

And yes,for the last couple of hours I have been studying the 5mm spacer cause it apparently do not have hubcentric lips.And if my new wheel have a round hub lips,then it is really not hubcentric.but if my wheel is flush on the hub,then it might be ok.
The 10mm have hubcentric lips but I agree with you.I think it would make my wheel stick out too much.
Probably the best way is to use 235 after all.
Too bad,cause I am going for the as wide as possible look,and no 8,5in width for the wheel that I am ordering.only in 9in.Well they have 8,5 in but with crazy 20mm offset ...

Nope. I have the OEM Sport pkg right now. No rubbing, no rolling. I'm hoping I won't have to roll, but I won't know until I lower my car. I did some measurements and I think I can clear the rear fender well with the Eibach Pro-kit. Seems to be the most conservative spring set.

purity · 07-28-2006, 03:12 PM

Actually I just installed my Eibach Pro Kit 2 days ago.They are great if you want the ride to be similar to factory ride.
It is soft at most small bump,but when you brake and accelerate or turn,the spring reduce a lot of the body roll we used to have before with stock spring.
I am still drive with the standard style 160 17in wheel,because my 19in as I say is still in order.
So the gap at front and rear still around 2 finger.
It do not look low enough.Hope the 19in will reduce the gap further.
Plus I heard that the H&R kit is firmer (beside lower) and for my area where the road is not smooth,I do not want my car to bump steer when taking corner.So I choose Eibach.And just like you, I hope I do not need to roll fender and Eibach will give me more clearance then H&R.

but deep in my heart I still think that probably H&R ultimately still have the better handling due to firmer and lower ...

Just found out on AC Schnitzer web site that they have Front Wheel 9in x 20in with ET35,the tyre size 245/30/20

Using the offset calculator above, I found out that this tyre is even larger in diameter then the 245/35/19 (a little bit).

And since the offset is 2mm more out then mine at ET37,I think my wheel and tire size will be ok just like the AC Schnitzer.Don't know if AC S roll the fender or not.

I think the 5mm spacer still the best solution,just have to find a way to make it hubcentric...

purity · 07-28-2006, 03:36 PM

thekewl1, I need your kind help again,

Would you mind to measure minimum the distance between front the tyre/rims with the strut you have right now?(the space/gap between your strut and the tyres)?

Because I just remember the way the front struts slanted toward the inside of the car,makes a 20in wheel have bigger gap between tyres and strut compare to 19in wheel.
Due to the angle of the struts.

Just by this,I will know if I can use my wheel without spacer or with 5 or 8 or even 10mm spacer.I think fender can be rolled easier,but suspension can only be cleared with enough spacer...

Thank you so much

I'm running 9x19 in the front with 2mm spacers... I was rubbing without the spacers. Would this be something I should be worried about as well (regarding hubcentric)? I have no idea how this works...

purity · 07-28-2006, 05:09 PM

Hi Matte90, for the front 9x19in what is your wheel offset?
And when you say you rub without spacers,does you mean the wheel/tyre rub with the suspension strut,or rub with other parts of the car (ie while turning )??

since you are only using 2mm spacers,I do not think you have problem with hubcentric.Cause your stock hub still stick out from the spacers long enough to go into the wheel hubcenteric holes and keep it/hold it center all the time.
The problem start when 5mm spacers are used because the length now become less then 7mm (from almost 12mm without spacers).Here I am talking about the lenght of the stock car hubcentric.

While your wheel usually have chamfered hubcentric holes about 7mm in depth.This cause the wheel have nothing to hold on to,to stay center.

Hope it help,

and please give me info about your offset.I really need it.thanks very much

Hi guys,

My setup is 18x8.5 35 offset with 235/40/18 all around. My nonSP 325 is also lowered by HnR sports springs. The front sits flush with the fender. Looks good, but rubbing when breaking or turning. I don't know which part of my car it is rubbing. Will a 2 or 5 mm spacer help?

My rear does not have rubbing issue, but it looks bad coz the wheel stays behind the fender. I'm just measured it an hour ago, but still not sure I should go with a 12mm spacer or 15mm.
