Track Package or Not?

[Tony Alonso]

Then when you get a chance bag that ride with an air ride suspension. So when you park it you can slam it down like a gangster. And then totally set it up for a good ride on the track or the street. Not active like the Magneride suspension, but certainly very cool and very effective.

Base suspension will probably be ok. Not a slammed fan :-)

The one thing all the reviews thus far concur on is that the rubber on the "R" eliminates the understeer.

If anything a really good set of rubber would eliminate that problem.

Balance is balance, it doesn't matter whether the rubber is hard or soft. I'm thinking they decided the R was for the most hard core people that could handle a car with less understeer, hence the slightly stiffer rear roll rate on the R.

It really makes me wonder how the base cars will handle without the "heavy duty" front springs. They may not have the ride adjustment, but may be less prone to understeer. The MR may go beyond compensating for that, but its nice to know there will be a factory piece I can bolt on if I need some more rear roll stiffness.

Tires matter a lot.

If I drove this car on the track with MPSS's on it I would expect it to understeer at the limit. It's 3800 lb car with a 54/46 weight balance on less than optimal *track* tires. The car is capable of more lateral G than those tires will allow.

All the parts make up a system. Different rubber, different springs, different set up for sway bars, different splitter, different spoiler. Just having that big rear wing probably means you can have a stiffer rear roll rate without unloading the inside tire too much.

Traditional shocks probably serve to increase the effective spring rate just by way of how they operate. I would guess that's why the springs that go with the MagneRide shocks are stiffer. The MagneRide shocks aren't fixed at a single stiffness like traditional shocks.

I will depend on whether you're on the gas or on the brakes and how hard. When you get on the gas, it will unload the front tires and plant the rears unless you manage to completely over-power the rears. When you let off the gas or are on the brakes, you load the front tires and unload the rears. More down force on the tires helps them to grip. So the car will be more likely to under-steer when you're on the gas a little, but if you try to turn in under braking the rears will have the weight transferred off them and you will get more over-steer.

^Tires change the dynamics of the car Hack....front and back. I know this from swapping out my tires for better rubber. Wheels change things with handling and braking, too. The explanation you give to FTD applies with the SS tires. What is clear is the SC's change it drastically. Remaining planted and gripping instead of begging for slight compensation or corrections as you're driving. Technology placing the Precision in the tool and not requiring it of the driver.

Here's the PS Cup tire:

For the 95% of my car's life which will be spent on the street, I'll gladly take a little understeer at the limit in exchange for at least a bit more compliance and wet weather capability. The PS Cup will be downright scary on the open road in a rainstorm.

Yup. When I went from MPSS to Cup2's in my C7 Z06, I immediately gained speeds and superb grip through the turns and bends at the track.

Love the Cup 2's for dry pavement in warm climate... I already have a second spare set for when my current ones are done.

I think we just all want our cars and find the "truth" for our driving styles, tracks, etc.

If it wasn't for the stickers... :shocked:

This is in fact very much what it will be like for most of us. As we learn the limits of our car. I used to have Michelins Pilots SS on my car.... I Put Mickeys on my second wheel set for a track day swapped out after first 20 minutes and immediately felt the improvement in handling the second run.

In the Winter I swap to my Leguna Seca Wheels and Pirelli Scotozero 3's.

Now I keep 2 sets of Pilots for my OEM Wheels and 2 sets of Mickeys AKA Cooper RS3-S's for my Forgestars.

My hope is that Ford doesn't distribute to the temperate climates these cars equipped with All seasons on them...like they did with a lot of the Boss's and GT500's.

If they do....???? I read somewhere that it was required since delivery to a colder climate with summers on them would be grossly negligent on their part and of course be like bending over for a law suit.

Yeah they were new takeoffs from another C7Z with <100 miles on it... many C7 buyers who won't ever track their cars end up replacing the Cup 2's with more streetable tires. Hence it's a good opportunity to buy a set at nearly half the original cost... these tires are approx $500 each! :eyebulge:

I know for sure that eventually when I change the GT350's MPSS tires to Cup 2's... there will be a major difference in terms of grip and handling at speed and at high G's.

I'll be using the PSS's for DD'ing and going all out for racing (well...close to it anyway). I'm still toying with the idea of using R888's but that's going to put me in a rough class for autocross full of big dogs like Z06's on 335 Hoosiers. Sure, yeah I could get some Hoosiers but I want to try and get at least 2 seasons out of racing tires. Just not really into buying tires every season + the $$ gets a little out of control.

I think the PSS's will be a fantastic street tire. You guys who are racing really should be getting some purpose made meats. Not because of leet'ism but because those PSS's, as great as they are, will be the weak link I'm sure.

I live in the North Country of the US in an area that gets 80-120 inches of snowfall and my Boss came with the stock Pirellis. Granted I chipped the shit out of them because they fall apart at 40 degrees and it took a little longer than anticipated to get a winter rat... but they didn't swap them out for different tires.

That sounds odd to me that they'd just switch. Sounds like a shady dealer move.

I am too about to place an order on a GT350 but first let me get this straight. Can I only order the Track package or Tech package but not both?

That is correct. You can only order one package.
