You completely missed the point, your post shows you have different brands of tire front and rear. Different brands have different characteristics and they look different. We performance folk know you should always run 4 tires of same make/model. Staggered fitment is not an issue.

Oh and I never mentioned price. Actually with all the work put into it I think you are very reasonably priced!

 

Tires are a tuning tool. Changes in compounds, sizes, pressures, etc., all can be used to adjust/optimize a car's handling balance. You certainly want to have the same tires side to side (unless you're running ovals), but not necessarily front to back. For example, a car that understeers may benefit from a harder compound tire and/or more psi at the rear. That will allow the rear to come around more easily, thus making the car more neutral. Total grip at the limit can be maintained with contact patch, but that limit will be higher when the car is balanced. When combined with the stiffer rear bar I use, that's what I've done. If you are going to rotate your tires then that's a different story. and you've clearly prioritized wear, etc., over balance. With asymmetrical tread designs and staggered sizes tire rotation is not as simple as it used to be. I don't worry about it because I have a unique tire at each corner and can't do it anyway. Your C6 Z06 probably does too (it did from the factory). The bottom line is you can't generalize without knowing the duty cycle. If you have a grocery getter where long tire life/wear, comfort, cost, and other factors are priorities then, by all means, have the same tires all around. If, however, you're trying to optimize the handling balance of the vehicle for a particular use, it's less likely you'll have the same tire at each corner. Even if you have the same brand, size, etc., on the same "axle" they may not be interchangeable if they are an asymmetrical tread pattern. I'm glad you "know a thing or two", perhaps you should extend the same courtesy to others when you don't have all of the information about what they are doing, and why they are doing it. I don't know what your definition of a "real car guy" is, but apparently it includes assuming everyone thinks the same way you do and does things only for reasons you do. Sorry, but we're all different and we do things for different reasons. Unless you're competing on a track it's pretty hard to say what may be better. I never said you don't know a thing or two. But it's clear you don't know me, what I'm doing, why I'm doing it, or what I've learned (over several decades, from some of the best engineers at GM and elsewhere, including on professional race teams) to make me want to do it that way. A C6 Z06 w/657 NA HP sounds like a fun ride, I hope you enjoy it. The LS into the Z sounds cool too. The LS is, by far, the most swap-friendly engine out there (yes, I'm biased). I also have a '95 RX-7 with upgraded twins (and MUCH more) but I often think about getting a '94 and dropping an LS7 in it. Too many toys, too little time. I work on my cars myself because it helps me understand and appreciate them so much more, as I'm sure you do too. It's a blessing and a curse because nobody else will then be able to work on it except you. I found that out when I had the LHU dropped in and I had to correct some mistakes made with the wiring and vacuum lines by the shop I farmed it out to. Par for the course. They didn't know why I did certain things the way I did either. A statement without all the facts is an opinion, as they say.

Thanks.

 

Dude, please use paragraphs. I actually live in Brighton, too.

I installed the wrong LCAs, and they ate my knuckles up. The ball joints only have 1 source, and that is GM. Once my knuckles got wobbly, it took out the front wheel bearings and made for some crappy tire wear patterns.

I worked 14 years at GM, got my SS from a Ford dealer used, and loved their ignorance as I got a deal.

As a GM employee (likely Engineer), you should be solid on what you have, and what's been done. These guys are trying to help. They aren't the problem. I am a Chassis Warranty Engineer, and I am not, either.

Which former GM employee will win?

 

10SSPanel - I'm glad we have an expert at last, that knows all (ALL) about tires and tire compounds. For a guy who cannot create paragraphs........

 

Ok, now we’re done . Over and out!
