APEX ARC-8 Fitment Thread

[BMWCurves]

that's the setup i will likely move to - 9's in the rear. i bet you won't rub with those tires, wes - the PSS you ran before are a bit chubbier than the 500s.

my setup:

18x8.5 ET38 square, hyper silver
3mm spacer in the rear
245/35/18 michelin PSS (tread width is 9.1" - these suckers are wide for a 245)
stock ride height - ZHP coupe springs, koni yellows up front, bilstein PSS9 dampers in the rear - both set fairly stiff
camber: -1.0F, -1.6R
no fender rolling
no rubbing without 3mm spacer in rear - slight rubbing in the rear under large compressions with passengers in the rear

Added.

For those who submit their fitment specs, it would be great if you could add pictures of the setup if you have them available

Here are mine....
Apex Arc-8 18 x 8.5 et 38 all around (wheels are custom powder coated using prismatic platinum gold)
Tires are Michelin Pilot Super Sports 235/40/18
Suspension is Koni FSDs and OEM springs.







Things to note:
I also keep a full size spare in the same wheel/tire specs in the trunk wheel well with no modifications.
I originally wanted 9s with et30 all around for the concavity but I would have had to deal with other issues:
-I just didn't feel like dealing with having to add in the negative camber (as i was told by APEX)
-I possibly would have had to roll my fenders.
-I wanted to use the 235s, rather than using 255s and deal with increased tram lining.
-I did not want to use 235s on 9s because i was afraid when stretched the ride would not have been as smooth.
-A 9 inch spare would not fit in the spare wheel well.

looking awesome, joey. two OGs in this thread!

re: your comment about the 9s... i think you're meaning 9.5? the 9" wheel has the same face profile as the 8.5" wheel does, and fits without fender modification or crazy camber settings.

the 9.5" wheels are a whole other ball o' wax.

Ahhh I forgot to specify, the 9 inchers that I was looking at were the et30s that had the profile 3 face. the et42s have the profile 1 face. I was looking at the 30s specifically because they came in that matte bronze finish. TBH I was hearing mixed things. some were telling me I wouldn't have to do a thing, others were saying I'd need add in the neg camber and modify the fenders. Although I believe that those modifications would be dependent largely on the choice of tires due to shape of the shoulder.

oh right, the ET30 ones! totally forgot about those.

yes, tires make a big difference... as well as camber settings, ride height, fender modifications. but 18x9 ET30 is still a very aggressive fitment, i believe more aggressive than 18x9.5 ET35, given the same tire size.

I think you should add whether it's a sedan or coupe since coupes seem to have more room for lower numbered offsets

Oh, good point! Will do when I’m home.

Huh, I didn't think APEX made an ARC-8 in 17x8.5" with an ET42 offset. I thought only ET20 and ET40.

Also, spacers? Fender rolling? Camber?
