i mean sure jaco has never sold multi compound tires. but for oval with the advent of smaller suppliers like murdock and rc4less multi-compound tires have been available for some time.
and at the factory level they've been available forever, not only available but in use! white-aqua-white anyone? hehe

So you can get a TC tire that changes componds the smaller the tire gets.
EX. of 2 stage tires???
firm at first and gets softer the smaller the tire gets.

No itīs different. The two compounds/rings are glued together so they sit vertically on the rim. So the harder ring is towards the outside of the car and the softer one towards the chassis.

don't they do the same thing with some rubber tires?

I just bought a used Pro4 in excellent condition from Chad. I'm new to the hobby, and before I invest a bunch of dough in replacement parts I was wondering how long the Pro4 will be competitive. I'm getting this car all ready, but now winter is coming so the track isn't going to be open, so will I still be good for next season?
I'm sure w/ practice me and the Pro4 will be able to beat new cars that come out, but I just wanted to know how dated the Pro4 is becoming?
Thanks,

If you are new, then I think it doesn't matter what car you have. Get some practice, learn how to drive and adjust your car.
As far as being old, the suspension parts (arms,hubs) are same as the cyclone. As far as the chassis, I find it similar to the FT tc4 (shaft drive, dual deck cars), the difference is that flex is controlled via a plate/bar rather than chassis thickness.
I was looking at the results of the races at IIC and saw one of the top finishers there drove a tc3, so one could say that those are still competitive.
Personally I like the pro4 right now cause you can find a lot of extra parts and cars on the 2nd hand market (read that as cheap).

HPI launched the pro4 in 2003. So far, the kit have been very successful and popular. I believe that the pro4 will be here to stay for a longer period. Especially now that they released a 2005 edition of the pro4. For me, it's the best shaft driven car in it's class.

I also beleive that the pro4 will be around for a while yet. If some drivers can still get results out of old tc3's, then im sure the pro4 still has a few years in it yet .
I will continue to use the pro4 for the 06 season, wether its a standard pro4, or a pro4 hara edition. The pro4 ive been using this season has been completely bog standard - no option parts....just a change in the setup from track to track. Just shows how competeitive the car really is

the Pro5 will be belt driven and will be released late '06 ...
oh...wait..Pro5 already been release....it's the cyclone..
j/k...
I don't see a Pro5 coming anytime soon now than HB released the cyclone..now racers have a choice of HPI/HB belt or shaft.. just like other manufacturer..Yokomo SD & BD.. Tamiya Evo and 415series..
Like Yokomo and Tamiya...the Pro4 can further evolve... ie aluminum bulkheads...

I used to be kinda anti-HPI guy before I get the Pro4
but eventully I got a Pro4 for some reason.
when I'm chacsing (or leading) other cars in the race, I can run
with confidence.I don't know why but I always feel some kind of
advantage with this car.
and actually it's faster........

what setup do you guys recommend for asphalt racing with foams? basic setup, not anything critical. shock oil, spring rate, camber, toe, ride height, shock position, that's really all i need to know.

I have a pretty good asphalt w/foam tires setup, I'll post it later tonight. I am at work right now.
