Quick question:
Which wheel will stick out farther, a 17x10 with et20 or a 16x8 et11? How much farther will it stick out?
Thanks
Erik

17x10, by 16.4mm. Very large difference.

The 17x10. About 5/8" more.

17x10, by 16.4mm. Very large difference.

Perfect, thanks guys.

If you hug the strut with a 16x9, then yeah 245/45/16 is possible with a lot of fender massaging. Think ET10 front or so, ET15 rear.

Jay,

Thanks. Follow up question. If I was to stay at 235 instead, does that open up more options? I'm seeing people run a 17" wheel with a 235. I'm trying to get the easiest and most efficient way to go, so it doesn't need to be a 17.

Thanks.

hey Jay,

i am looking to refinish a set of wheels with widened lips. Original offset is et13 and stock lips are 2". What is the correct way to calculate the offset for every 1/2" or 1" i go bigger in lip size? thanks, pm me back if you have info.

thanks!

Sweet. What spacers if any did you end up using?

I ended up going with a 10mm in the front, but in order not to seriously rub when i turn, i had to raise the car AND camber the front in 2 deg. The rear dont have any spacers, but i think that you could easily fit a 10-15mm spacer if you wanted to sit a tad more flush. Im gonna roll the fronts eventually so i can lower it back down. But im really stoked on how it looks. SO much meat in the front and rear! thanks jay.

how much work would http://www.importatlanta.com/forums/...d.php?t=234330 those take, pending i get new tires all around, and spacers....? On a stock e30 suspension, and then lowered on IE springs, bilstien shocks, and adj. camber plates?

No 235/xx/16 tires.

Divide the added width by 2 and subtract that figure from the original offset.

2.5" lip: ET13 - (0.5" / 2) = ET7, rounded off.

Nothing else. I'd suggest 20mm front and 25mm rear for spacing. And 215/40/17 tires again.

I've been looking for 16x8 rota slipstreams but seems like to get them the way I want I have to wait 2 months so I can't do that. I found a different set of wheels but they are 17x8 (et25) & 17x9 (et20). I have a 87 325is on bilstein sports & h&r race. Now I think they would fit but i'm unsure about tire sizes. I was thinking 215/40 up front w/ 245/35 in the rear so they would be the same diameter. or is there a size in between that I could fit on both rims? Any suggestions?

Mystikal...
I'm sorry if these questions have been asked before and I know this is an e30 Forum...
I just bought a '96 328is...
I've had an '84 325e for years and I still have it, but I am new to the e36 world..
I wanna buy some wheels and suspension for the e36...
I am probably going with GC coilovers for the drop...
For the wheels, I am probably going with 18's or even 19's...
If I want a flush fitment with no staggered wheel widths (unless I should run staggered widths on an e36), what offset am I looking for?
What wheel width do I want, Front and Back?
What is the max tire width I can go with the max wheel width you recommend?
And what is the stock Hub bore on an the e36?
I like the set-up you got going in your sig.
Finally, do you know of a good e36 factual website like Strictly eta is to the e30?
Thanks for your help. You should be paid for this. I only hope you can answer my questions before you decide to throw in the towel.

I may be looking to sell my bbs rsII's



now for my question; I bought a set of staggered m contours for my e36.



I may instead be getting a 5 lug e30, e36 m3 in front m roadster in back. the tires I have are 225/45/17 up front and 245/40/17 in back. Will the tires fit for an e30 or should I get something smaller

[Stephen]

17x8et0 It should poke a little im sure. And yes im willing to stretch.

Tire size and Fender work necessary?

[bmwsone01]

Jay, Thanks for this INFORMATIONAL thread! my question:
I have 15x7 BBS RS +25, for front and rear, and i am running 205/50/15s.
Can i run 20mm spacers all the way around?
