  1. I would argue that an r888 is even more wide.  I have seen a few z guys, and lots of Miata's running 205 r888's on an 8 or 9 with great results, but race radial tires tend to run a little wide.  I thought we were talking street tires here, in witch case the 225/45 rs3 is about the best option for an 8 or maaaayyybbee even a 9.  As far as what series stretches best there are entire forums dedicated to such and would suggest your time is better spent elsewhere seeking that vital information.  You are right wide wheels look good, but the best part about them is they enable more contact patch.

  2. I'll take a 4 pinion r160 over a 2 pinion r180.  Though I've had no problems with my own 2 pinion r180 (3.36) as the old dried up 225/45's let loose too soon.  I haven't tried too hard with the 330's as I have enough other stuff to fix.

  3. Subaru r160's are readily available in 3.54, 3.9, 4.44 and lsd is not that hard to find.  They are stronger than an American Z car r180, significantly lighter than a 200 and more efficient.  Many 510 guys road race them over 300 lb.ft. and I've seen Subaru guys drag race them with 400-450 whp and 3300 lbs.  A few Subaru guys have problems with them at those levels, but they tend to have the extra 10% in the center diff.

  4. zredbaron spun a dynojet to 264, a bit more compression (12:1), deduct about 3% for the reduction in compression and you have 256.  This is what an optimized head/cam will do on a quality 3.1 with a very good header and theoretically too small 40mm carbs.  The power is in the head, always has and always will be.

  5. The problem is with air going around the rad, instead of through it.  I've seen a 5" intercooler in front of a 4" rad and NO cooling issues making more power than most guys here would consider sane.  If everything is sealed properly and the air has no where to go but thru, it will go thru.
