Ideal Square Setup on Stock Suspension?

Hey fellow Beast Tamers

I'm looking at ordering a new set of shoes for my beast and wanted to run this by the hivemind before I pull the trigger on custom rims.

I've got a stock suspension setup that I'm quite happy with, but it's time for tires and I felt that now would be as good a time as any to get into a square setup to both allow for tire rotation and reduce understeer.

I've already converted to Vorshlag 75mm Studs, and I want to make sure what I'm ordering is going to work the best.

A traditional square setup with 4x Style65 rear wheels gives you 18"x9.5 wheel at +22mm. Given that I'm not married to OEM sizes, is this still the best size to order if I'm planning on sticking with a stock suspension setup? What size front spacers should I use for this setup? I don't care about hellaflush and have no desire to roll or tuck fenders.

Any help from you geniuses would be much appreciated!

3mm spacers on front should give you just enough space to clear the struts. Can still seat the wheel on the hub. 275/35-18's all around. The favorite tire around here is the Mich PSS, although there are a few other alternatives.

If you have studs and nuts, get some plastic black covers, from 5 feet away, they will look like bolts.

Regards,
Jerry

You need 3mm+ spacers up front to go square. My car ran 275's square for quite some time on stock suspension, now on Dinan 1.5, no issues.

If they're going to be custom might as well make them have a perfect offset (~15-19) for the front so no spacers are needed and then put small (3mm) spacers on the rear if you like, no?

You could also consider going staggered X9 up front and X10 in the back (I think with correct offsets it fits) if you're not 100% sure about the square setup. If I were to go the custom route I'd probably put 255s on a X9 and 285s on a X10

Also, got any pics of the NSX and M5 together?

what's the best spacer to use up front for stock suspension M5 with stock rear 18x9.5 Style 65s with 275 Michelins? is it ok to use a 10mm or 12mm spacer since those come with a full hubcentric lip? Or will that rub with the fender?

Current:
-2001 Anthracite M5 (daily)
-2008 Black X5 3.0si (wife's mom mobile)
-1998 Cosmos Black M3/2/5 (track fun)


Gone but not forgotten:
-2000 Steel Grey 323Ci (first Bimmer / daily / track)
-2001 Slate Green 525iTa (wife's mom mobile)
-1989 Diamond Black 325iX (winter fun)

Your going to be getting close and it might depend on which tire you are running (PSS are a bit fatter than many) and what your front camber is set to. I haven't measured, but I run 3mm with PSS and I could probably just clear if I used a 10mm but might have some contact at extreme loading.

I ran PS2's and now PSS' for a long time with my stock suspension using 5mm spacers. The 3mm spacer was just not quite enough with either tire. I've since moved to a 3mm hubcentric spacers on new Ground Control coilovers. Works perfectly.

3mm spacers upfront for sure, but consider keeping the track the same front to rear and run spacers front and Back

I also have a 2002 M5 with a completely stock suspension and just picked up a staggered set of 65's in excellent condition. I am going to use the 8" fronts for a winter square setup and the 9.5" rears for a summer set.
I also plan on doing a couple autocross's each summer and maybe a track day or two here is Colorado.
That being said, I plan on running Continental Extreme Contacts 275/35 and have been given mixed information on what size spacers to use.
Here are the suggestions owners have stated:
15mm front, 10mm rear
3mm front, 10mm rear
5mm front, 10mm rear
5mm front, nothing on rear
3mm front, nothing on rear

My 2 goals are: staying as close to stock OEM specs OR trying to widen the stance as much as possible without the potential for any wheel rub.

Which spacer setup leaves the beast with true "square" stance?

Recommendations? Thoughts?
