I have to say I'm super jealous. I wanted to do 19x11 so bad. I wasn't willing to risk losing money on HRE R101's not the cheapest wheel to just try to make a custom offset work. So I went 19x10.5 in a +53 offset with 305/30/19. They will be going on tomorrow with K-Mac Camber kits. So we will see how it goes.

Definitely wanting to go a bit lower to get the stance right on it but I'm worrying about that when I get my wheels and tires.

its not so much the individuals who are not willing to share the specs. I went underneath my car multiple times and spent so many hours making precision calculations and measurements to find the right offset and right ride height. It's more that the shops and the wheel companies are not sharing the information so that they can get more customers to get their product. Also, wheel companies and shops will not quote the customers the same specs that I have because they don't wanna cause any issues with rubbing and therefore making super conservative decisions. This is my own car and if I wreck it or damage it, then its on me, I can do whatever I want with my car.

FORGESTAR SF5V
JaeJin Sohn,
Great post! Thanks for sharing your experience.
Sweet looking setup!
I just ordered a set of Forgestar SF5V.
19x9.5 ET +30 front
20x11 ET +55 rear
ETA is 12 weeks.
The salesman stated I should have no issues with this setup at stock height. I am currently running stock height. I've seen some nasty pictures of tire damage from tires hitting the inner lip. I am wondering about rolling the rear fenders. Should I just do it for good measure?
Tires I was thinking Michelin PS4S.
Front: 265/35R19
Rear: 305/30R20
Here is a set of my wheel calculations because I want to see every C63 on 11" rims with 305's.
FRONT:
Stock:
8.5 in = 215.9 mm
38et
215.9 / 2 = 107.95 mm
107.95 + 38 = 145.95 mm
215.9 - 145.95 = 69.95 mm
Custom:
9.5 in. = 241.3 mm
30et
241.3 / 2 = 120.65 mm
120.65 + 30 = 150.65 mm
241.3 - 150.65 = 90.65 mm
Difference:
Inside: 150.65 - 145.95 = 4.7 mm | 0.185 in.
Outside: 90.65 - 69.95 = 20.7 mm | 0.815 in.
REAR:
Stock:
9.5 in. = 241.3 mm
56et
241.3 / 2 = 120.65 mm
120.65 + 56 = 176.65 mm
241.3 - 176.65 = 64.65 mm
Custom:
11 in. = 279.4 mm
55et
279.4 / 2 = 139.7 mm
139.7 + 55 = 194.7 mm
279.4 - 194.7 = 84.7 mm
Difference:
Inside: 194.7 - 176.65 = 18.05 mm | 0.71 in.
Outside: 84.7 - 64.65 = 20.05 mm | 0.79 in.

He has BC Forged
Front: 19x9.5 et30
Rear: 18x10.5 et57
He stated his rear fender is rolled. The rear fender also looks pulled. I don't want to run 305's on 10.5" wide rims. The 11's with et55 place the tires in the same place according to my calculations. RDO247 also stated he has his vehicle lowered and is using KMAC adjustable suspension hardware.

Rear guards are rolled only, no other modifications to the metal guard.

I waiting, maybe another month to receive the rims I ordered. I haven't rolled renders before, I have my heat gun ready but didn't buy the roller yet. I don't know but I have read the fender gets pulled as the guards get rolled- Reshaping the fender. Bodyshops in my area aren't familiar with rolling fenders. I talked to one that stated he had done it on 2 BMW's but started to sound like he was setting me up to hose me. I have to see if I can roll these fenders. Better I screw it up rather than paying someone to screw it up.
As for tires I have been eyeing Azenis RT660, which are 200 tread wear tires. Those AR-1's are not available in my area, extra shipping cost makes the price less favorable. RT660's are slightly wider but those 305 Mickey Thompson's are even wider.
If 275's fit on the front then 265/35/19 RT660's should as well. With the extra effort of getting these rims putting 4S's feels like a waste. According to the experts Cup 2's aren't designed for cars this heavy, sidewalls are too soft. That narrows the choices down to some others that lack performance (Supercar 3, P Zero) or are unavailable (RE-71).
Heat up and cool down, break in period, and finicky tire pressure make the AR-1's seem like a bad choice for daily driver. Nitrogen narrows the pressure differential between heat up and cool down, which seems like it would work well for RT660 or 4S. RT660's have lower speed rating, the W rating worries me on the quality of the tire. How can 4S be rated better at high speed but have less grip?
Leaves me to wonder what the best tire option is.

Do they hook well from a standstill? Particularly for just a stage 2 tune & downpipe combo. I realize you have upgraded turbos so it might be different for your case.
