Staggered vs Square Setup 18”

[R60BBA]

I am considering getting a set of 18” 8.5 et35 for my Z4C.

Is anyone running a square-set up on their Z4C?

Pros and cons/general feedback over standard staggered set up would be much appreciated.


(My car is used 80% street, 20% track.)

What size would you being looking to run OP?

Think you may struggle on the front of a 3.0SI for a wider rim.

I just edited my initial post, please refer.

8.5" ET35 is 18.4m further out than standard which is too much.

Aim for 12mm or less.

I got my setup squarer by going down to 245/40/18 on the rear and keeping 225/40/18 on the front as 235/40/18 rubbed lowered on B12 and 10mm spacers.

Really? Ahh :?

My alternative is a staggered setup of 18” 8 et35 and 18” 8.5 et38

Which do you think is better?

Use a website like this to see how it changes fitments. You want no further than 15mm out at the front and 20 at the back if you're not drastically changing camber

Thanks, but would like to prompt that my post is more about the difference between staggered vs square than whether the wheels will fit.

Oh right, but your question was which offset is better?
Staggered - understeer but looks nice and fits
Square - over steer but might not fit on the front

I run exactly this setup on my coupe, fitted with standard (non M) tyre sizes.

Just to clarify this is a square 18” 8.5 et35 setup?

Yes - 8.5 x 18 ET35 Team Dynamics Le Mans rims. No rubbing problems so far, but the front wheels definitely look wide relative to standard.

They look sweet mate.

Do you reckon you could install lowering springs with this set up without rubbing?

I run 18 x 8.5 et35 square set up. No issues on my Z4C. Fills the front out nicely, it doesn’t seem to affect the handling much, but I don’t really push it.

That said so think I will fit 10-15mm spacers on the rear to “even out” the arch fill.

 

[Steve84N]

Maybe you get away with it standard ride height but that setup would definitely rub lowered with Eibach springs. I was running standard 8J ET47 front wheels with 10mm spacers and with a 225/40/18 it touched part of the liner ever so slightly until it wore off something tiny like 0.1mm.

Take from that what you will but I also had stiffer anti-roll bars and maximum front camber...

 

[brillomaster]

not quite a square setup, but I run a 245/35 front and 255/35 rear on 18x8 and 8.5" rims for track work... wider fronts just gives a bit more neutrality to the steering when exiting corners and trying to get on the power - with narrow fronts the car would always want to drift wide on the exit.

oversteer is never a problem in the dry, trackday rubber at a 255 width is more than ample to keep the rears locked down. could still do with a bit more camber on the front though.

 

[R60BBA]

I went with 18” 8 et35 / 18” 8.5 et38.

Will post pics once the wheels are fitted.

Wheels are on!

Looking good - but then you've got a good starting point with a Montego Blue Coupe!

 

[hopz121]

Wheels look great OP

What tyre sizes are those?

Have you lowered it?

225/40 + 255/35

No but planning to!
