Hi all,

I've read a bunch of the threads around here (esp. glamcem's awesome build thread) but I am not sure if I've seen a solution that works for me.

I'd like to run a set of Apex wheels with good track tire selection, but use a setup that requires no strut grinding. I don't care that much about getting as wide as possible. I'm more interested in good track tire wear, being able to max out the camber, and ideally, rotate tires front/rear and left/right using a square setup.

Apex told me a lot of people use 18x10 et25 square with 285 width tires (285/30/18 or 285/35/18?). My understanding is that with -2.6deg camber front, these will *not* clear the strut without significant grinding and a 5mm spacer. It seems this would also be true for a 19x10 et25 square setup.

Does anyone have a good solution that I haven't considered? Would I need longer studs to use a 5mm spacer safely on the track?

I'm also worried about sufficient tire selection and price. I think 18x10 has a ton of slick options, but it doesn't matter if they won't bolt up to the car.

Also -- if I did a 18x10 or 19x10 et25 square setup, would the rear fitment be OK on the fender-side without rubbing under hard cornering?

Thanks!
Mark

18's will rub at the knuckle (sorry, can't remember who test fit the 18's). 19 x 10, +25 will require a 5mm front spacer for aggressive negative camber, but no grinding required and does not rub. In my opinion, you should go with the longer Silverado studs, but some don't. Quite a few guys (me included) are running this setup with either a 285/35 or a 295/35 square setup. Strangely, some have been able to get more negative camber than others. My guess is the build tolerance in the suspension plus the accuracy of the alignment machine both come into play.

This is all correct. I would HIGHLY recommend switching to Silverado studs. With a 5mm spacer you’ll only get about 5.5 turns of the lugnut and it is recommended to be at least 7 turns for track use and our lug nuts are torqued to 140 ft-lbs. you want as many threads holding that as you can get.

I wonder if you could do 18x10 and still get good camber if you ran the MMS camber plates.

19X10 ET25 will work on all four corners, no matter what you throw at the car. As far as slicks, I am not sure how many 19 inch options there are, but for non slick track tires, there are plenty.

Wow, thanks for the great answers all. So I am guessing a 18/19x10 et25 in the rear fits nicely flush with the fender like the stock setup? (Wheel is 1" narrower but lower offset to compensate?)

The 18x10 option sounds interesting if I got camber plates. I did hear the Moreno ones may be defective design-wise though, judging by the cracked ones I saw here on the forum. Waiting to see what's up before I make a decision.

No problem, see the linked thread for photos of fit and poke.

Anyone have part numbers for the Silverado studs? How much longer are they?

You answered your own question somewhere in there.

Also, why not just run OEM SS 1LE or ZL1 wheels and tires? They're known-good.

[RideZX6R]

I'd consider the ZL1 1LE reps instead as they weigh the same, cost marginally more, but have Camaro offsets as opposed to re-purposing BMW offsets for a Camaro

(this is coming from someone who currently has 3mm spacers up front, -3.0 deg camber and strut grinding with the 19in APEX wheels and NT01s)

Will 18" wheels clear the brake calipers?

Do you need spacers to make that setup work?

I like the idea of those wheels because they are camaro specific, but in a square setup, you'd either have to run a 10" with an et 20 all around (not sure i'd like a 10" with a 305 on it, too much tire for 10"). Or, a 10.5 all around, with an ET14. While that's a good option up front for clearance, that's close to 23mm further out in the rear, might look wild.

[Roostie]

I agree that the offset you'd need to run a square set of wheels that's wider than 10" could look odd on the rear. A bit of "poke."


My Camaro is a V6 1LE and I have a set of 18x10 ET25 Apex FL-5 wheels, very light at only 20.5#, and has the correct satin black finish. To have sufficient camber adjustment range and strut clearance, I'm going to run 5mm spacers on the front axle, and then to get enough turns on the lug nuts, I got some "extended thread" nuts from motorsport-tech.com . The *giant* OEM lug nuts do not seem to fit the more modestly sized nut pockets (that's not the right term, I'm sure) on the Apex wheels, so with Apex wheels you need to change lug nuts even if you don't run a spacer.

Nut pockets, haha. I know what you mean I test fitted a set of 19” 10.5 et22, with and without a spacer and the lug nuts were very close to the “nut pockets”

I have some photos of my findings i will share soon.

Do you need spacers to make that setup work? NO SPACERS, I am about 1.5years and 7k miles in on this setup with autox and track days, no rubbing to report.
