Hoosiers are the extreme end of R-compounds and are close to being slicks. In a car that does not experiance camber gain under compression of the suspension (i.e. like a 911), you will need to run more camber (beyond street acceptability in terms of wear life) to maximize their use.
None of which really matters because they last SIGNIFICANTLY LESS than normal "r-comps" do. Generally a set of Hoosiers is good for a weekend, maybe 2.
They are DOT legal by definition but should not be run on the street unless the track is literally down the road from you, because all you will be doing is wasting very expensive rubber getting there and back.
Dan, can you provide a link regarding the RA1's being slighty faster than the R888's? I was under the impression (based on what I garnered from the laptimes posted in the racing forum here), that the R888 was slightly faster than the RA1, and that the NT-01 was slightly faster than both, with having the additional benifit of lasting longer. Not trying to be confrontation, just looking for information so that I can get my facts straight with more recent data.

the ra1s being faster I have heard racers claim this. also when I spoke to a technical guy at toyo this week, he told me this but he claimed it was from not changing the setup on the car to specifically be set up for the r 888.
interesting that you observed otherwise on the racing forum.
no confrontation felt here

I have run R888 and they wear well with aggressive street alignment but they are no Hoosier R6. I suspect to get 6 days from my R888 and I'm lucky if I get 4 from hoo-hoos but they stick like a mother f***er.
You NEED -3.2 camber upfront and about -2.2 in the rear on a 997 and thats at the far end of aggressive, you can't run them on the street (no tread and they'll heat cycle out), you SHOULD have stiffer springs, you should heat cycle them once and then let them cool for 24 hours (read: you need 2 spare sets to cycle through properly and extend life as much as possible) and last but not least they don't start working until you get them up to about 175 degrees F.
That said, they're cheaper than MPSC and MUCH cheaper than the new trefeos.
For your average guy, R888, MPSC or trefeo are good options. I've never tried the R1 but I hear it's sweet too.

Yes, in general, pirelli has outlandish pricing in Canada. P-Zero tires are $200 more expensive than PS2s for my car. I'm looking into the trofeos right now, but i'd imagine they're similarly priced.

AFAIK you cannot get RA-1 in Canada any longer. If you want a tire much like it get the Nitto NT01.
I've been running R888 for a few years, they make a good street/track tire but are not as fast as many others. We do get a substantial discount by belonging to and racing in a CASC club though, and I don't have to change them to get home.
I guess it comes down to whether you want to drive them to the track, how long you want them to last, and how fast you want your lap times (is there a timer running?)

Hey Dan, What do you think of the 048's on the track? Did you have to heat cycle them? I'm looking at an almost new set that have been driven on the street only.

They are really good on track and fine on street. They don't heat up on street so won't heat cycle as they won't heat up on street. I was going to mention the ones on ucr but obviously you found them...be sure they haven't been below freezing as it could damage the compound. You will enjoy these.

I occasionally check in, but don't post much.
BTW, just put in my order for a set of R888 from TalonTire. TeamToyo discount and contingency from TalonTire made it an easier decision.
Unfortunately it might be end of May before they get made and then get here from Japan.
I even looked into getting a set of Goodyear Eagle RS, but sizing sucks unless running 17" or larger.
