Has anyone here run the Hoosier Racing Slicks(non-DOT)? I have a chance to buy a set. Would they be as good as the Michelins?

Pretty damn impressive when I ran on them a couple of weeks ago.......A6 level grip which never seemed to "go away". Cant wait to sample them again soon.

Not in love with the rear sizing available for my car...

Make sure they are the new radial slick , not the old VRL's. They just came out with new radial slicks within 10 months or so...

Hey Danny.

Thanks for the reply. Yeah, the size is 25.5x11.5 R18 front and 28.0x12.5 R18 rear. I'm running a 4.10 rear end with lots of torque, so I think the 28's will work

How do I tell if these are VRL? (and what does VRL stand for)

VRL = Viper Racing League

VRL only come in two sizes. 18x305/30 and 18x335/30

Is that the size that is molded in the sidewall? I have never seen Hoosier 18's with the sidewall designated in inches. The new R80 and R100's(I will using some of these 305/645-18 scrubs for the first time this weekend) have metric designations and have the R80 or R100 imprints. They had a previous generation of GT60(they were molded with GT60 imprints) slicks that were used in GrandAm and had metric designations; I tried some of those scrubs and they were about equal to R6 scrubs after chemically treating them with Formula V and 4 seconds slower than Dunlop slicks at Laguna Seca(1:43.7 on the Dunlops.) You should find out exactly which Hoosier slicks you are buying, it doesn't sound like the new, fast R100's and some ancient Hoosier slicks are no bargain.

Yes those are the GTs.

az55

Yep,

It turns out they are the VRL slicks. Other than having to change set-up to accommodate the 28" rears, what problems would there be using these for TT.

Not enough grip.

the VRLs would be good track day tires and to start out, You will get lots of USE, but not as fast as Rs or As

VRLs in 28" rear? I think those are the GT tires.

If its NASA TT then you take a whopping 30 points for slicks! That moves you up at least 1 class.

AU N EGL

Not the Hoosier VRLs. Those are the only Slicks were there is No points added. Why? Not as fast as R6s and not even close to A6s

now the Hoosier GTs will be differnt

Kubs

I looked it up. My mistake

az55

OK, now I'm really confused. These tires are 25.5x11.5 R18 and

28.0x12.5 R18. They were originally intended for Grand-Am.

I'm going to call Hoosier and see if they can clarify.

Thanks for all the feedback.

i need 2 fronts and 1 rear of the VRL if you are going to pass on them please let me know thanks

AU N EGL

those are the Grand Am Tires, not the VRLs andnot the GT tires

VRLs ONLY come in 18x305/30 and 18x335/30

Put them on and run them

But you will take a point hit for slicks

preston

So what's the input on an R6 vs the real slick ?

The slicks in my size cost about $75 more apiece. The one comment above is "r6 grip that lasts longer". That sounds a little wishful.

Anyone else have any experience ? The slick SHOULD have more grip than the R6, but I would also expect it to go away a lot sooner.

If the slick actually held up better than the R6 even one more trackday (4 sessions) but preferably two that would make the decision a lot easier.

az55

Hoosier confirmed that. They were for a Viper that did not run in the Viper Racing League. I'm going to try them. No problem with points as I will either run TTR or ballast the car and run TTU.

My main concern now is whether or not the set up will be as good as when I run the Dunlops.
Oh well, experiments can be fun!

This is what I received from Hoosier

Thanks. Where would the GT compound fit compared to the A6 and R6 ?

Tom

it doesn't, nothing like them at all.... totally different compound composition. Much higher grip level.

If these are GT60 scrubs(3+ years old) They will be as good as the Dunlops on the warm up lap, it will be downhill after that. I bought mine for $20 a tire and they were worth exactly that! Do you have a close up picture of the sidewall?

redtopz

Good info, thanks.

Sidney004

I found them. They are the 2007(or older) DP tire, not the GT:

They are heavier than the GT's and probably the new R100's because they are designed to accomodate high downforce Daytona Prototypes.

All of my comments were with regard to the GT's, so please disregard.
