Tires
Dunlop SP 9000? I want to get the best tires I can. I am gettin 235-35-19 and 265-30-19. And SO-3 are unavailable in those sizes.
I have T1-S on my old E36 M3, Vadim@Evosoprt runs T1-S on his C32, Harris runs T1-S on his C32. All of us like them. There may be just "slightly" better performing tires, but usually there is nothing with great size availability that can touch them on performance.
This is even more true if price is factored into your decision.
And T1-S tire wear is improved over Pilot Sport or Pirelli, as well.
I would say IF you were running stock sizes, you might find a better tire (Pilot Sport? or S-03) but at a substantially higher price and lower treadwear.
You will like the Toyo. Also T1-S performs even better in short sidewall, say 19 than T1-S does in say a 17.
Dunlop 9000, well nobody really recommends them, dry and wet is less than Pilot Sport, and treadwear is worse than Pilot Sport, S-03, Pirellis etc. 9090 look better for dry and wet, but treadwear is bad, and 9090 dont fit 19 inch.
