Look, I'm not surprised at the skepticism here. I certainly raise my eyebrows every time I read how people can feel a difference due to a down pipe or reflash or lighter pulley or BBK. The best I can say is that I controlled my environment as much as possible and felt a difference at launch. Take what you will, leave the rest.
I noticed MUCH more of a difference before/after my road tune from a Base Map than I did going from 16x6.5 205/55 to 18x9 235/40 to 18x8 235/40 to 17x8 245/45 to 17x7.5 235/45 in terms of acceleration. Handling, and vehicle dynamics, on the other hand, is a whole nother story.

same. My tires have close to a 10 lb difference to the wheel. Shaving off a couple of lbs from the tire I can see making a difference, but not so much from the wheel itself.

Lets not forget the cost factor - Lets say we all agree that the lighter weight will perform better even on the street and you can feel it in the buttdyno. Is that feeling enough to offset the added cost. For my DD I went with Rotas for cost and l liked the looks.

Also, most track days are fun and only a few are really trying to win or be the fastest and this is usually related to drivers skills. We all know that to be the fastest in competiton takes alot of money, is it worth it? I guess if you have it. Anyone can be fast in a $90K race-prepped subie, not everyone can afford it.

So make sure you consider your "bang for buck ratio"

the whole end of this thing is the kiddies thinking that they want and need steamroller wheels on their cars....which means heavy wheels and tires

when something like a 17x8 rpf1 with a 235/40 or a 245/40 is plenty big and plenty light


but IT AINT KOO

Well I obviously don't want to spend $$ for a track worthy setup because I know I won't be tracking my DD. I just want something more substantial than stock, but I think that's been answered with around a 17 or 18x 8 being quite sufficient.

Thanks
