The last set is just about to get shipped out. I'll get more material on order as soon as I get this latest shipment of stuff cleared out to get another 5 sets but it'll be maybe 6-8weeks before I have sets fully available. Best to follow on IG if you want to keep up to date with what I have in stock since I can't directly advertise here.

I'm going to post these here as well. 18x11" +52 wheels at a reasonable weight of 22lbs.

https://www.apexraceparts.com/wheels...ang-wheel.html

Let's compare them to the 18x10 +38 RPF1s. What are the chances of making this work?

Well compare to my aggressive setup of 18x12 +32, I need to move the strut in about 5-10mm, and do a little inner wheel well mod to clear.

Wow, okay so that settles that, I'll stick with the 10s for now. The 11" +52 are 7mm closer to the strut than your 12" +32. I don't think I want to address that with a spacer. Thanks for the input.

Plus these actually look good, they're cheap, have acceptable weight, and have a fine reputation with BMW track guys.

They also have a 10" +43 version, which I'm probably getting. No reason besides looks, RPF1s are the same price and 3 lbs lighter, but I can't just spend the rest of my life rolling around on RPF1s.

+43 should be great up front (less mexipoke due to a spacer, assuming they need one) and fit fine in the rear with Dallas' arms.

How much can you move the lower strut mount? are you making a double adjustable CA? I think I need about 15mm for an 11.5" wheel. I'm tempted to get one made.if its doable to mount the strut a whole lot vertically

18x10.5 NT03 ET30 on 285 RE71R is tried and tested. i only have cut lip on the rear and Whiteline caster + 15mm spacer upfront. the rubbing on plastics stops eventually

If you look in the picture I posted above, there's about 10-15mm between the shock and the upper control arm. With my billet uprights that increases just a bit with the upper arm angled down about 8 degrees more. My plan is to remake the lower arm to move the mounting point inward enough to get to a happy minimum clearance. Im not necessarily planning this for anyone else because I don't want to worry about what others shocks bodies have for clearance, but in my case I can get more inboard tire clearance which will be critical for the biggest of big rubber.

I may have some slug inserts to make the lower position slightly adjustable to like 0, +5, +10. But I wont make the over all length adjustable. I wont design anything with threads in bending regardless if its oversized. That's just bad engineering.

Oh yeah I'm pretty sure the 10" +43 will fit great with these arms. here's what Apex told me:

Thanks for your email and sounds like a really cool build. To answer your question, yes the 18x10" EC-7 will clear your brakes no problem. They offer a ton of room and even clear the newer Mustangs 15" 6 piston setup if you ever wanted to upgrade your brakes in the future. They would also fit even if you didn't run a spacer, there's that much room offered.
But I'm sick in the head and I'm wondering about the 11" +52
