Ted...while doing some searching i've come across numerous negative post towards Hipari tire. I want to know where your opinion comes from. It seems to me you dislike it due to the "drift trend" which is huge in your area right now.
The reson i bring back this old thread is because today while shopping at some of the japanese book stores i came across the newest REVspeed magazine and instantly was reminded of you. Its known to be one of the best technical motorsports magazines internationally and i'm not talking drift. Anyway, they just did a test on wheel size using 3 diffrent widths, same tires.
The first set they used would be what you would recomend. 235/40-18 on a 18x7.5 wheel.
The track times came out to be 1'03.369
2nd set 235/40-18 on a 18x8.5 wheel.
The track times 1' 03.103
3rd and final set was 235/40-18 on a 18x9.5 wheel.
The track times 1'02.680
There was alot of other data included such as temps on the inside, center and middle of all 4 tires but lets not get too deep into that. This shows clearly that everything isn't about the biggest contact patch. Hipari has alot of great effects and is used in more motor sports then just drifting. On street tires, hipari aids alot in making the sidewalls stiffer which we all know effects the handling of a car by alot. If it didn't we'd all be circuit racing on drag radials.
I just noticed your opinion on Hipari was a very strong one but with no real reson behind it. I may not post often and thats because i choose not to bicker and argue. This isn't a post against you, just something i thought i could clear up with the help of REVspeed.

I dont think many guys running hipari style are trying to get the most from their setup, its mostly for looks... some of them run horribly poor tires for a spirited driving and thats even more laughable.

A 265 or 285 wheel with nice sidewalls would deff. have taken the 9.5 235/40s but remeber we drive rx7s and...
No way a 9.5" will fit up front unless you run some stupid hipari on it...
