18" OE Rear Wheels up front?

davem3fan · 01-29-2009, 01:21 AM

I searched, but couldn't seem to find anything on this...
Does anyone have pix of OEM rear 18's on all 4 corners?

E39 M5 guys sometimes run rears up front for tire rotation and to "minimize understeer"... Anybody playing with this?

Square set-up is what I run. OEM rears in summer, OEM fronts with winter tires in the cold times. Sorry, I don't have any close-ups of the summer fronts, but they clear and don't stick out.

That Christmas tree pic wins the best utilitarian use of an M3 award - brilliant!

Thanks!

...So what I really need is another full set of OEM 18"s
Guess I'll put a feeler out there.

My car looks a lot like yours!

If I ever need to pull a small stump out of the yard, I'll tie a rope to the rear and yank!

The Christmas tree photo was taken down by Gilbertsville. I'm in the Allentown area every couple of weeks, and may be moving to the Wilmington DE area in the spring.

I went to this set-up for the same reasons you stated from the M5 board. This car really doesn't seem to have a lot of understeer, however.

I'd show you the set-up in person, but won't have the wide wheels in front for another couple of months. Considering that I had to have a winter tire set-up, this worked out well for me.

RJ, that is great to know. I am also interested in running a square setup. The only thing I worry about is how it might change the handling? Increases understeer, maybe?

From what I have read, increasing the front width to create a square setup decreases understeer.

This argument should be made for those who think the M needs more torque.

What size tires are you guys running when using the OEM rears at all four corners?

Yes indeed. The OEM staggering reduces oversteer (by introducing some understeer) which is deemed safer by car manufacturers.

Square will definitely exhibit noticeable oversteer but only if you're really pushing the car with DSC off.

I think on 9.5 rim you can go 255-275 safely. I've heard of some going to 285 which is pushing it IMO. I'd imagine most are staying with OEM 265 or maybe going to 275. If you're going square for track you want max rubber for your setup.

I'm running square but with 18x10 rims @ 275/35 per corner

STALKER · 03-09-2010, 05:54 PM

I was hoping to use 4 OEM rears for track.
Using 265/35 front tires and 275/35 rears.

Can you use 40 series rubber?

saeedg48 · 03-09-2010, 06:12 PM

AHAHAAA that tree is hilarious.

MrHarris · 03-09-2010, 09:29 PM

I think you can use 40 series rubber in the front but you won't be able to turn full lock. 40 series rubber in the rear, 275/40 is a for sure.
