Streetable track tire test: Hoosier TrackAttack Pro

My cousin had a moment in his Camaro ZL1 1LE on the SC3R on a cooler fall track night, he came out of the pits after the sun had set and found himself facing the wrong way after turning into T1 lol.

 

Boggles my mind that the GM lawyers allowed them to sell SC3R as OE fitments.  How could folks not get in trouble?  I suppose if nannies are employed and calibrated heavy-handed, you get away with it.

I'm guessing your cousin turned those off?

I would like to see this same test using a heavier car. like a BMW M4 or Porche 911 or Corvette.

Tire Rack will be doing that this spring, as will Jonothan Benson of Tyre Reviews.

All:

I looked into the new Hoosier TA for my Boss 302 LS and after reading the literature ( 3 full pages) for the tire I selected a new set of GY SC3's instead. The break in and heat cycle requirements fior the TA's are very specific as in specific for Road Course use versus Autocross use as are the recommended pressures for each use a well as for specific car weights. Also, they detail specific chassis set-ups as well for optimium detailed. Hoosier spells out the tire is not intended for high banked super speedways (Daytona?) or high speed and banked tracks like WGI without specific pressures and camber adjustments.

Great company with a great product line, but for your regular HPDE participant like me with 30-40 track days over a typical season on many different tracks; Summit Point, VIR, NJMP, etc. , I will stick with the GY's or Bridgestones, both of which I have used in the past.

FWIW, I treated them the same as every other 200tw -- nothing special -- and got great performance out of them for many, many laps.  They are now down to 1/32 and quicker than ever.  How much quicker?  Stay tuned for that story...

Some of that web site verbiage is CYA liability stuff.  Getting parent Continental to approve development of a legit street legal motorsports oriented tire like this took some doing.  This is a whole 'nuther level of performance beyond the Conti ECF.

In reply to kb58 :Yep, like all those formula cars.

I'd say the difference is Hoosier provides actual support and tech documentation where most tires are more like "Have fun, try not to die!"

949 Racing offers a color called Beskar, which tells you all you need to know about how awesome they are. 

Teaser alert:  Just submitted a long-term test story involving most of the tires in both this test and the P1 test.  Lots of really interesting data.

Tidbit: We got 4 total hours worth of hard laps out of our TAP's.  That doesn't include any of the out laps, cool-downs or drives to/from the track.  And they only slowed down when they corded.

They may even have gotten quicker than they were in that initial test.  How much?  And for how long?  Stay tuned...

Warmup is quicker than SC3R but slower than RE71RS.  Kinda like CRS V2.  But, it's not no grip when cool like SC3R, which will try to kill you (and did so during our testing when asked to perform before it was ready).

We ran the second test with the top down for photo aesthetics :)

Normally, the top is up for better aero.  And it really does work well with the top up. 

Down is a little better than no wing, but the car was definitely not as planted as top-up.

I have a smaller wing (Verus high efficiency) on mine, but it's a very obvious demonstration of turbulence if you get up to 70mph with the top down. The wing is moving around like crazy top down, but completely motionless with the top up. With the top up and a decent angle of attack it makes a massive difference in high speed cornering and I've taken a couple seconds off my lap times at local tracks. A rear wing is a good lap time per dollar mod, only thing cheaper per laptime reduction is probably tires.

That said, it's nice to be able to take it off and run STR or run at the track in full Miata mode on a nice day.

In reply to Andy Hollis :

Thank you, Andy! Really looking forward to reading the updates.

As an aside, have you had any experience with the RCES? Curious how it stacks up to the Toyos et al.

No.  Limited market -- low on the priority list.

Soooooooo excited for this.

Just to add about wheels. Tilt casting has been around a long time. It's not rocket science. Also Team Dynamics has been using Tilt Casting for 15 years.............
