Most important days in the history of Genn III Vipers:

1) Release date of SRT-10;
2) Release date of SRT-10 Coupe;
3) Release date for sticky tires in 345-30-19

This is HUGE for you guys. Let me tell you, putting Kumhos on the rear of my Gen II was hands down the best mod I have (I even gave up on 19s in order to do it).

How does "special order" = available? Last I heard (from Luke at Tirerack last week) the rears were supposed to come in "later this month," but with tire mfgrs that's often next month, or the next month, etc.

And does anyone know the difference between the two tread compounds? (obviously one is for road racing and one is for autocross, but which would be stickier overall?)

 

[INSOMNIAC]

I have been wondering how it would be to run a Hoosier R6 on the street..
The R6 would be much more stickier than Kumhos.

It sure wouldn't be fun if the tire blows out to pieces while going 3 digits on the highway.

Of course they don't want people using them on the street, primarily because a wet road would be like ice. But if they'll withstand triple digit speeds and repeated high speed cornering on a road course, I have a hard time seeing how they'd be dangerous on the street (assuming the street is dry). I suppose they could be more likely to blow out if you encountered a pothole or other rough surface, but I think we're going to find out how they do on the street as soon as they come out.

This is excellent news.

Who makes a lightweight wheel in the stock sizes?

...a lightweight, inexpensive wheel. That's the key. Those Hoosiers would be worthless if you have spend $2K minimum on wheels for them.

I think that the chances of finding lightweight racing wheels in stock Viper sizes for less than $2000 a set is right around 0%.

Yep, I agree and it's a shame. You may as well find some cheap 18's and go the e-brake relocate route.

 

[SRTRICKY]

how about stock 19" wheels and putting these hoosiers for the track? Keeping the HRE's for the front since the front doesn't matter...Would that work well?

 

[Viper X]

For wheels, call Parts Rack for the Sidewinder "black" wheels. They are the best thing going in a light weight 19 inch Viper wheel.

This is good news. Hopefully other tire manufacturers will follow with sticky 19" street tires. Both of these new tires should be great on the track when warm. On the street, it is unlikely that you will be able to get them warm enough to do much good traction wise for high hp cars.

 

[CCBrian]

Hoosiers would be horrible on the street. They take several laps at the track to heat up. Once heated up for a track session, they heat cycle when the tire temp falls below 130 degrees...at long stop light on the street? After 3 or 4 heat cycles, they harden up. I can only run a set of Hoosiers 3 or 4 track sessions and they they get very slick...even if most of the tread was still there. They would never work as a street tire...the compund is much different than a street tire or even a "R" compound tire. One on many reason Tire Rack says not to run on the street.

 

[Racer Robbie]

Here are the sidewinder weights for front and rear are 34 lbs lighter compaired to stock. I weighed them last week. Forgeline also males a lighter tire in the factory OEM sizes for both front and rear. I went with the sidewinders as they were very close in weight and cheaper.

 

[SylvanSRT]

comparing the shipping weights of the "blem" SRT-sidewinder wheels to the stock 10 spokes there was 30 lbs difference. there is huge difference in the feel, turn in is much improved and car feels more nimble

 

[Chuck 98 RT/10]

Unless you're being chased by the cops it would be a waste to run Hoosiers on the street.

This could be true about the road race compound, but I have a hard time believing the autocross compound would act that way. Autocross tires have to heat up quickly for what is usually a 20-30 second run, and then they sit for 30 minutes or more between runs. If they heat cycled the way you described, they would become useless after 3 or 4 runs and I can't imagine anyone would buy them.
