Hmm.. still a couple of weeks left before ordering the RSRs.. 4-6 weeks on the Vossens after the down payment today...
Decisions decisions..
Vossen VPS-314 - 9/+25 / 10.5/+25 - gloss gunmetal - ordered today.
FIGS RC-F, RC350, 3IS, 4GS Essential Kit for lowering - ordered today
- Front LCA Bushing Pressed into OE Bracket: Yes (refurbushed)
- Front LCA Bushing Type: Standard (no offset)
- Front LCA Bushing Duro: High Performance 90 Duro
- Rear Upper Arm Bushing: SuperPro Polyurethane
Still debating on tire type/size. Now I'm wondering about the coilovers..

I've still yet to see even a single set of properly fitting wheels here. I'm just trying to be honest and helpful. No ill will.
For example, HRE recommends 255/30/20 and 295/30/20 on 9 and 10.5" wide wheels for the common plus 1 from OEM sized RCF wheel buyer. The more rubber you can lay down, within reason, is always a good thing per motorsport. HRE measurements are usually spot on.
Next, a properly fitting wheel and tire package should not rub lowered let alone at stock height. It should not require you to go skinny on the tires or stretched in any way, shape or form. So the only way to meet these parameters is to go custom. I've yet to see a quality wheel vendor make a set bespoke to the RCF which makes complete sense. Volk. No. BBS. No (non-factory). OZ. No. Work. No. Never. Why? Because there isn't enough volume and likely never will be like the congested BMW M3 scene.
If you really want to do it right going the lowered route, you have to look into FIGS suspension parts as the RCF offers zero adjustability unlike the M3.
So here's a sample, do-it-right checklist the ROK way:
-Custom spec 20" 6061-T6 forged wheels (e.g. HRE, Forgeline, or if cast, Work)
-FIGS lowering suspension components
-Quality rubber (as wide or wider than stock)
-Quality adjustable coilovers (e.g. KWv3s just released)
I conjecture, strongly, that anything less is worse than stock (i.e. ghetto fab).
I hope this helps gets the brain juices flowing toward the right direction.

I have a few things in mind if I do in fact jump into an RCF in the next month or so. Something meaty

285/30-20 295/30-20 Difference
Diameter inches (mm) 26.73 (679) 26.97 (685) 0.24 (6) 0.9%
Width inches (mm) 11.22 (285) 11.61 (295) 0.39 (10) 3.5%
Circum. inches (mm) 83.98 (2133.14) 84.72 (2151.99) 0.74 (18.85) 0.9%
Sidewall Height inches (mm) 3.37 (85.5) 3.48 (88.5) 0.12 (3) 3.5%
For only 1/4" difference in diameter, it does look like it makes sense to bump up to 295.. only problem is the more limited availability between the brands. You're pretty much down to Pirelli P-Zero and Michelin Pilot Super Sport. I was leaning towards the Hankook V12s..
EDIT: Thanks for the push. 295 SS's it is..

Comparing stock tire specs to the 295/30 20 doesn't look like it's all that radical. 7/8" wider and less than half an inch taller.
PS. I mistyped earlier. 9" +25 on the fronts, not 9.5".

Wait.. WHAT? Are you saying that the clearance is so tight that wider wheels will interfere with aftermarket exhaust?? I'd love some clarification on the statement!

I ordered some custom one-piece forged wheels, specs are 19x10 fronts and 19x12 rears.. Can't wait to get them and see how they fit!
