I am a wheel snob with a great deal of experience with wheels for the 111 platform. I have imported, tested and sold more varieties of wheels for these cars than anyone in the world.
Really. Here's a list: BBS, Rays, Toybox, SJR, Kodiak, SSR, PB Racing, TD, Monolites, stellaCORSE, ETHOS.
I place my priorities on wheel selection as follows: 1. Performance, 2. Quality, 3. Styling, 4. Price
I consider the fitment as most critical. This includes: Diameter, Width, PCD, Offset, Hub-centric, Weight and Strength. I won't put a wheel on my car that is heavier than stock. In fact, I look for lighter wheels - especially at the front for steering feel. I won't put a wheel on my street car that requires a spacer or center ring. I am open to spacers on race cars for various tire fitment, etc. We deliberately choose specific offsets based on performance on the track and street. We have widened the front track more than the rear in an effort to dial out understeer. Some of these items are very nuanced and not something that everyone will pick up on or 'feel'.
There are some very good manufacturers all over the world. Some of the best aftermarket wheels for our cars come from Japan (Monolites, stellaCORSE, Toybox, BBS, etc). But our ETHOS come from China - built by a high quality supplier who builds OE Camaro wheels. They are superb and a great value. I look for wheels that are JWL or VIA tested in an effort to determine quality. Wheels can be cast, low pressure cast, or forged. Each of these processes deliver benefits and have disadvantages.
This is personal taste. I styled the stellaCORSE wheels with my friend Neil and feel I know a thing or two about what looks good on a 111. I like 16" wheels at the front of the car from a proportion and performance perspective. I feel that wheel size reflects the shape and 'weight' distribution of the car and the 16" front and 17" rear looks 'right' to me. I don't really care how good a wheel looks if it violates #1 or 2 above. The current 17" Monolite wheel used at the front, does not meet my requirements.
We have sold wheels at many different price points over the years. I would suggest that the SSRs and ETHOS wheels have been the best value on the market. But nothing beats the Monolites in pure performance - though the price is high. I would rather stick with stock than violate #1 & 2 above for a cheap set of wheels.
You can disagree with my priorities and that's OK. It is your car and you get to have fun the way you want. I'm a driver who gets a great deal of pleasure on how a car feels when I drive it in the back roads and tracks. Pushing a car close to its limits is important to me so I prioritize differently from those who don't. It's your car, do what you like. Just understand there are trade-offs...
