Traction isn't king, staying off the go pedal is. Unless you're actually racing... Then yes traction is very nice to have. All the traction in the world just means you hit that tree head on, not sideways.

Very informative thread. Awesome advise!

My MPSS's are currently backordered, been waiting 2months now. The only reason to wait this long (and more waiting, no ETA) is because what everyone is saying about Michelin's.

But not getting traction until the 3rd confuses me. Should I cancel the order and get Nitto 555s?

What I think you are looking for are tires like the SCCA Autocrossers use. They use a 200 tread wear tire. If you look up the Tire Rack and look for extreme performance summer tire.
This is probably one of the better tires

Hankook also has a good one

At this power level, " street " tires don't get the job done.
You need a 10 or 11" rear wheel.
The tires that will " hook ", aren't much good in the rain.
The smart money would be to buy a beater for a DD............GOOD LUCK !!

No problem!

If your not pushing more than 500 whp and 500 lb of tourqe the MPSS will be fine, actually it's all about the torque level that really breaks the tire loose.

When my MPSS wear out I'll replace them with michelins again, I got approx 30% more traction than the stock goodyears btw. For that reason people love them, I get it. They are also a very good looking tire, I'm not a big fan of the nitto look. The goodyears were worn out around 3k miles, the MPSS have 7k on them and they are probably 50% worn.

They also did very well at road course racing. BUT if I were racing the car 1/4 mi I would go with the nittos. On the street, against another car with street tires, there's no competition. At the 1/4 mi track however I would get spanked by 5.0 with slicks or drag radials often. Again it's all about your torque levels.

Just for fun I really need to make a video of the 1-3rd tire smoke, it's doesn't seem likely this could happen but it does. This isn't dumping the clutch, this is rolling in to the throttle in each gear. If you dump the clutch you may be in 3rd gear burning the tires and only moved 10' lol. I'll try to get my GoPro going today and get a video.

I totally

Just to be clear, everyone is referencing the 555R's correct? Because the regular 555s are garbage. I'd be interested to try the 555 Gen 2's though.

Also for Nitto, the NT05s and NT05Rs are another good choice.

Gabe

NT05 is not really for hooking with tons of power, it's more of an autocross tire.

The NT05R is the next step up from the 555R, but even worse in the rain.

Unfortunately, the OP seems to think he knows more than anybody posting in this thread, so he and his over-boosted car will probably be on the news covering some horrific crash where the driver lost control of his Mustang.
Hopefully he doesn't kill anybody when he does.

Ecostang

Correct, I'm referring to the 555r. Thanks for clarifying that!

laserred38

Yes and yes on the NT05s, but yeah I'd really only suggest the Rs for his power level, and not for rain use. I know guys that have driven their full bolt-on s550s in the rain on the Rs, and it's not advisable whatsoever, but doable...that's with 450whp though, not another engine's worth on top of that.

ford20

I wouldn't necessarily say you were putting 400-450HP down. You were putting down all 700HP but had tire spin which cost you a lot of time. I bet you were trapping higher than those cars and your back half numbers were probably better then theirs once you caught traction. Then you have to go ahead and look at the suspension differences in getting the car out and moving etc.

Suspension and tires will help enormously in getting all that power to the ground. It is fun to blow the tires off though haha

The G-Force Rivals are awesome tires for autocross!! A lot of people seem to be using them with some really good success. Nice choice on those.

Once I wear out my MPSS I am thinking about going with the RE-11's. I have heard FANTASTIC reviews on them.


+1 to that

Those stock Goodyears suck!! Ford sacrificed performance for wet traction, price and a little bit of longevity (when handled properly). If I was OP I would also look at the Toyo R888's. They still have some good road manors in the wet and have rave reviews everywhere. They are also popular on the Cobras which are putting down some good numbers and shouldn't be too bad of a DD tire depending on where you are int he country.

The Pirelli Corsa's that were on my car hooked like crazy! They would on a warm day hook from a dead stop with some throttle control and they handled amazingly.

tom281

Why so harsh, you drive a supercharged car too right? Are you arguing just because he wants to drive it daily and perhaps you chose not to, or just because it's more power than yours so you think you can handle yours but he can't handle his? Just didn't understand the need to assume he's absolutely going to wreck it because it's "over boosted" in your words.

Gabe

No, I'm arguing because he asks for advise and when he gets it he seems to shi* on it.
Strikes me as a young kid whose daddy paid for everything and doesn't know anything about how prepping a car to be boosted is more important than any other part of the process.
Build the suspension, get some real tires, and THEN boost the thing.
Or, boost it to the moon, then realize you're spinning just breathing on the gas pedal, then jump on forums asking what tire will cure the problem.
No tire will.
It's a whole system that's needed.

Allen,........do yourself a favor and go to Youtube and search for some videos of high powered cars to see what they are running. That will be a great indicator for you.

Ecostang

I agree with you and understand that, I just did a poor job of explaining what I meant. A car with slicks that doesn't spin and has 450 whp is basically putting that amount of HP down the entire track. If I launch and blow the tires off through 1st and 1/2 way through 2nd I'm putting less than 450 whp to the ground while spinning, but as soon as I hook then I'm putting down my 700 whp. If you averaged my HP based on traction from one end of the track to the other I'm only putting down the equivalent of 450 whp. I don't know if my explanation made this more confusing or not, my logic still could be wrong

Once I learned I needed better suspension and better track tires I decided to build a race car instead. I didn't mind the few engine bolt ons that I have but I didn't want to modify the car any more than that. I didn't want to beat it up that much either, track days are hard on our cars. I dont ever plan to sell the car and want to keep it mostly stock and in good shape so my kids can have it some day.

bob

This! So much this!


I remember the first time I ran DR's and forgot I had DR's and the ground was just damp on some new pavement and new paint. I dove into an off ramp and right as I hugged the turn and the passenger rear tire kissed that new paint on the road I suddenly remembered I had a set of Nitto DR's on the rear. I said fudge but not really and away I went doing a few pirouettes ( three as I recall ).


Anyways to the OP


With almost 800 horsepower to the rear wheels your going to have traction problems no matter how much tire you've got in the rear and whatever suspension mods you have. That's life with a powerful street car.


The only time your gonna have some really good traction is with a set of super sticky drag tires at a well prepped track on a good day where the pavement is just right. The rest of the time your just going to have to use some restraint.


Frankly I'd get a good summer tire or good performance all-season tire if you frequent places where the temp can get below 40 degrees (or a snow tire if it snows a lot and keep a set of summer tires for when the weather is good).


They wont be as sticky as a set of DR's but in the case of the summer tire or all-season tire your going to get better all around performance especially when the road is wet.


I've driven the GT500 with its 700+ whp in all sorts of weather with okay to great summer and all season tires and have done fine unless I'm trying to go full throttle from a dig or up to 3rd gear.

12 to 15psi, a little water, use your line-lock to heat them up !!

I found out the hard way about temperature and tires on my car.

I run the MPSS now and I'm at around 550 to the wheel and I cannot matte the throttle until probably third gear and even then it's doing it very carefully.

On a street tire at 700 you're just not going to hook up unless you run a wide drag radial and even then... probably not.

Like others have said a drag radial will suck in the rain and corners so if it were me I'd run the MPSS and be very very careful with the car.

Basically that's what I do now hehe and my "traction control" in my '07 is basically non-existent. It went off one time at a stop sign because it was on an uneven hill... that's the only time it has ever gone off.

When I slid my car into several trees it never activated :/

On the newer cars you have active TC so you're better off than us in the older cars... but you're still going to have to be very careful with that much HP.

Kind of like what others have said... it's cool to say, "I have 700 hp" but the practicality of it is you're probably much better off with less because you'll be able to use it... and you won't have to baby that throttle as much.

At my power level I still have to baby it in first and second... my car is also a DD.

laserred38

Traction control didn't do me any good last year when I got into a slide, other than leave me dead in the water when I started to correct the slide, allowing me to be t-boned...and insurance blamed it 100% on me for breaking traction. Even though the idiot that hit me had plenty of time to brake/swerve. And it was his idiotic driving moves that caused me to take evasive action in the first place.
