The only place you have to worry about rubbing in the front is the front strut. The amount of clearance you have will vary depending on how you have your camber adjusted. If have your negative camber dialed in using the factory adjustment on the knuckle / strut and knuckle is tilted inwards creating more negative camber therefore tilting the top of the tire in towards the strut therefore reducing the clearance between tire and strut. If you are using camber plates you can tilt the knuckle all the way out and use the camber plate to tilt the whole strut inwards creating negative camber and maximizing tire to strut clearance. Or if you are running stock alignment then the easiest way to tell is to jack a front wheel up or turn to full lock where you can stick a finger or something 15mm to 20mm wide between the stock Pirelli and the strut. If you have 15mm to 20mm clearance (you should with stock alignment ) you should be able to use any 325.

I had the Pilot Sport Cup 2's installed. They fit good, plenty of clearance.
And I have a fairly aggressive alignment in order to minimize tramlining

Based on comparison of specs for the RE-11 and MPS 4S, I should be able to run 325 MPS 4S on all 4 corners. Right? (on OEM Z/28 wheels)

[D2M]

Not a Z/28 but this is where you will have to check for clearance. Camaro wheel wells are huge, the car was designed around a 29" OD tire so the only place you have to worry about rubbing is the tire / strut area pictured. The amount of clearance will depend on the amount of camber dialed in at the knuckle / strut joint adjustment.

Thanks - my Penske struts are a bit thicker.

How much camber is shown in that picture?

Yes, the Z/28's 11" front wheels are wide enough for 325/30 . . . perhaps not the optimum width for that tire size, but still OK.

Have you considered cutting a little off the end of that endlink stud?

Just to clarify. The picture above is NOT a Camaro, just a general Google image for " tire to strut clearance " to be used as an example.

Neither the RE11 nor the RE11A is even relevant in conversation when discussing cream of the crop street tires in 2016. It is unfortunate that Tire Rack's surveys, while extremely helpful to the layperson, don't always paint a true picture.

I wish people put more emphasis on testing and doing their own research, and knowing tread compound(which CANNOT be interpreted from TW ratings) trumps tread width in most applications.

Again, this is for people who care about getting around the quickest in autocross or track day applications, who also drive to events on the tires that they race with.

The Pilot Sport Cup 2 is arguably the best street/light track tire available right now. You'd be doing yourself and the Z/28 a disservice by showing up to a track day on MPSSs or RE11s.

Bridgestone RE71R for autocross duty(if running in SCCA's 200TW Street classes), even though they're only available in 285/35/19 for now. 305/30/19 is coming this summer.

If you're autocrossing just for fun and want to keep going fast, run the Trofeos or the Pilot Sport Cup 2.

Hankook's RS3v2 and Yokohama's AD08R in 305/30/19, while no longer top tier tires for autocross, are still excellent street/autocross/light track day alternatives.

I noticed you had SCCA FS national champ in your sig.what dpnypu think about the new Michelin PS 4S? Supposedly these are supposed to not get "greasy" after they get hot, yet offer the cold performance of the old PSSS...

[Fedzl1]

Anyone with Michelin PS4 325 all around or recommend 305 for the front?

Rears are MPSS 325/30/19. No rubbing anywhere.

I don't believe the MPSS 325/30/19 can work up front. It's too wide.
I went with different tires in order to accomplish the look I was after.

Tire Rack would not sell me the MPSS 325/30/19 without consultation, said they were too wide for the front. I went with Conti 305/30/19. Looking at the width, I probably could have went with Conti 325's all around.

That's why you don't put the car the tires are going on. Tire Rack doesn't know the Bridgestones run narrow.

325/30/19 RE 11 is a perfect fit on 11" inch wide rims. Shouldn't be the case but it is.

The PS4S was used by many competitors during this year's One Lap of America. Reports are that is a fantastic all-rounder, sacrificing a bit of ultimate grip for gobs of wet weather capability and excellent wear characteristics.

A friend/fellow autocrosser who was lucky enough to enter the competition this year with his '15 1LE said he had enough tire afterwards to repeat the event and mileage all over again.
