Yeah I admit, it's less than ideal way to create a lip. Honestly big lips weren't really my goal. Allow me to take you through my thought process.

The stock tire size is 215/45-18. The most common replacement is 225/45-18, but the car responds nicely to 235/40-18. Also in the case of the HTR Z III's 235/40 was cheaper than 225/45. More grip + less money = I'm sold.

The measuring rim width for the 235/40-18 tires is 8". The ideal offset for an 18x8" wheel with 235/40 tire on an MS6 is +50, which other than being stock on the RX-8, is rare.

These are the right offset and reasonably light weight. A less-wacky lip is also available but these were on clearance. So all else aside from the lip being equal I went for the cheaper option.

I do kinda like how they look. A drop should clean things up but like I mentioned, other things have to come first before more car parts.
