Installing R6 Hoosiers on my GT3.2 RS. Anyone have experience on these, and comparing them to MPSCs? Would love to know what I can expect in grip and wear.

 

a lot more grip when up to temp...no warning if you exceed....wear will be measured in heat cycles

 

Ditto.
As stated, no warning at the limit of adhesion. When you hit it ... you're gone.

Is it complete spinout or do they slide some? How does PASM react or work in that situation?

 

Grip, nothing better. Life about 8-10 heat cycles. They may still show tread after that mind you, but the best of the grip is gone. FYI, Hoosier has a good contingenty program for NASA events. I use then for NASA TTS class and the free tires sure help out.

Glad you posted. I knew you would know. What is 8-10 cycles? I have had buddies run about 5 weekend events on the tires. Does that sound right? Next time you get a free set, ask for 2.
I bet you can't wait til the white car arrives!!!!!!!

 

A heat cycle is when the tires are cold, brought up to temp run at temp on the track, then cooled. That's one heat cycle. For the tires to work at there best you can get 8-10 cycles ( two race weekends (SAT/SUN) IMHO) Keep in mind as I said after that (8-10) cycles the tire are not as fast. Even after the cycle limit the tires will work better the any regular ( non race compound) street tire. So you can get lots of "time" on the tires before you use them up and show cords, but that does not mean the tire are fast. Hell I drove them on the street on my GT3 for 500 miles and they worked like a champ in the dry and were scary in the wet.

 

Well, that is interesting. New they are about $1300. MPSC's are about $2000 for a set. On MPSC's, I can get about twice that much use or more. My stock tires have 2 full hard weekends, 1 half day, and 1 full day of 4 solid hours running. And they might still be OK. I guess we will see. I just wanted to try the Hoosiers for one run. It almost sounds like the MPSC's are better or longer use for the money.

 

I would say the MPSC tires are a soft high traction street tire but the Hoosier is a race tire that has a DOT stamp. You are correct, I would think the MPSC would last longer overall. The question is what are you looking for over all. I was looking for a high traction track tire that needed to be DOT spec ( per rules) and had a contingency program so I could pick up free tires. For me the numbers work over all.

Well, I'm a rookie. I think I can drive better than most, but still I'm a rookie. So, I really wanted to try them. All you guys were running them. Had to be a reason. I'm sure I will be even faster around the track in the Hoosiers? But I do like some lenth of time in ownership so I'm not feeding it tires more often than I care to afford.

 

I get about 12 good HC and they are done (wires sticking out of them) at about 20 HC

I would guess they are about 2 secs a lap faster on a 2 mile track roughly

You will not go back to cups once you try them -- they are faster and cheaper

limited sizing in 19 inch sizes... you might want to consider 18 inch track rims

I run 255 fronts and 335 rears on my .1RS in 18 inch...

 

I highly recommend returning the Hoosiers and sticking with the cups. You're totally wasting your money on a set of Hoosier tires. You'll probably run slower lap times and will definitely get less runs out of those "Charmin" soft Hoosiers. Save your money,,CC08GT2!!!!

 

We must ignore this renegades opinions.

 

I love Hoosiers! Have been using them for ~7 years on my race cars. I get good feedback from them and use them 2-3 weekends of DE. When I was club racing, I'd get a bit less time based on working them pretty hard, plus always wanting a fresh set, but I don't care so much for DE. I'd highly recommend them to anyone at (real, not perceived) intermediate level or above.
I think of level based not on lap times but experience with tough situations (spins, maneuvers, etc). If you haven't saved it a whole lot of times, you're not very experienced IMHO - but I think a discussion like that would take this thread down a tangent - sorry about that -

 

Not a great tire for DE's unless you have an open wallet. When they say 10 heat cycles they mean it.....so with that in mind say you do 4 sessions a day at 1 DE...that is 4 heat cycles. So 1 weekend of DE they are done...maybe 2 more DE sessions which is 1/2 a DE day.

One thing I will mention we have seen some new Hoosiers fail on higher HP cars like my friends 996 Turbo. The side walls get a blister and the tire carcas seperates and BAM...it blows and usually takes out a 1/4 pannel and some of the turbo radiators. He is now trying Yokohama's.
