Help me achieve Optimal Ride Height / Camber. Apex, KW CS, AD08R

[8k3]

19x9.5" ET22 Satin Black APEX ARC-8 Wheel Front - Yoko 275/30 AD08R
19x10.5" ET22 Satin Black APEX ARC-8 Wheel Rear - Yoko 295/30 AD08R

KW Clubsports please free to recommend:

Front and Rear ride height (fender apex to ground in inches)?

Front and rear camber?

Toe, Front and Rear?

Priories in order: Trying to achieve zero rub, ultimate handling, whatever is left (comfort etc I don't care)

Thanks

FYI: whatever camber I ran last time chewed up my rear and front inner tires 8-10k in, they were Michelin PSS

Is this a street car or a track car? Based on your text, you don't care about the comfort level associated with lowering the car?

In regards to your alignment, that will vary based on your height, but generally what I have read to be optimal is somewhere in the range of -2.6 degrees up front with zero toe and -1.8 degrees in rear with 1/16 toe in.

Street car mainly, that I track here and there. However, it's not a daily driver so comfort isn't an issue

Its going to rub in the rear. I think you're going to want to max out camber and run as much toe as reasonable to avoid it.

Hmm and I was worried about the fronts being a 275/30. Thought a lot of ppl ran 295/30 with no issue

I have ran 295/30 pss on 10.5 et 22 and et 25. Both rubbed over large bumps.

The ad08s run wider than pss.

I haven't ran that exact setup in the front but from what I've read on the forums it should work with a bit (lot?) of camber.

I am running 295/35-18 on 10.5" et 25 in the rear with Michelin PSS. I might graze once a month, at most.

My track wheels are EC-7s in 10.5" et 27 in the rear with G Force Rivals, which are about as wide and square of a tire as you can get. Again, when I went with those wheels on the street, the rub was rare.

Your et 22 is going to get you into a little trouble with AD08s in 295. I love Apex products, but IMO, they kinda missed the boat on the offsets in their 19" lineup. The offsets on their 18" wheels were perfect. I'm not quite sure why they didn't just scale those up. IMO, et 22 is too aggressive in the rear to run 295 tires rub free.

Perhaps consider selling the 19" EC-7s and grabbing a set of 18s? With a good drop, 18s look so much better on the E92 M3 than 19s anyway.

Thanks. Any spacers out there that may help ?

Ran this, diameter is less for a 295/30 vs 265/235

I don't think spacers will help in the rear. To the contrary, I think they will make the situation worse, because the issue is outer, not inner, clearance. For example, a 5 mm spacer in the rear would effectively give you et 17. At that point, you risk the tire shredding the paint on your fenders, especially if you run something like an AD08 in 295.

I do believe you will need spacers on the front, however, in order to clear the KWs. In the case of your fronts, the problem is inner clearance on the springs/perches of the KWs. I think you will need at least a 3 mm spacer in the front and perhaps a 5 mm.

Yes, the 295/30-19 is a smaller overall diameter than 265/35-18, but the difference is not very significant. That said, this was one of the reasons I went with 18s, as I didn't like the idea of a thin, 30-profile tire in the rear. I much prefer the meatiness of 295/35 or 285/35, but then I drive in an area (downtown San Diego) with very poor roads.
