What is needed to setup my suspension

There are several benefits to doing this even with the standard size tires, before going crazy with alignment changes and larger wheel/tire sizes.

For one. Most of the extremes have larger tread blocks, which not only establish a higher level of contact patch for the same size, but wear in a much more uniform fashion. With this you can clearly gauge how much and where the tires are wearing most. There is no point of adding additional camber if you can't accurately use all of the available rubber on standard sizes.

In motorcycle terms, you've probably heard this banter called "chicken strips" on the tires. Similar lack of wear lines can be established on normal car tires. gauging these wear lines give you an idea of how the camber is effecting tire contact patch and also how much steering input you are putting in and where in relations to corner loads and throttle modulation.

Another form of measurement you'd should start implementing immediately if you don't already, is measuring tire pressures and heat margins across the tires. A cheap harbor freight of homedepot infrared gun can gauge heat across the tire accurate enough to tell you how much heat you are balancing across the tread. In these summer conditions you may find it easy to go from a cold 35psi to hot 41 psi in a relatively short spirited run, but getting temps up in colder conditions is equally important.

For the sake of understanding what you are feeling, its good to also randomly test different tire pressures so you know what overinflated tires feel like compared to under inflated. The gas station air pump should be your new best friend.

You have several back roads i'm sure you take advantage of already. But instead of trying to go outright fast or pushing the limits. Push the limits in different ways. Form a solid pace and intentionally try to induce understeer and oversteer by playing around with your steering input speeds as well how early or how late you enter a corner with modulation of braking a acceleration. Measure the tires accordingly after each run. You may say this is stupid or unsafe, but this is the point of establishing a slower overall speed.

Practice makes perfect, build up the aggression gradually

Very well said, good sir. Reason why I am looking to increase negative camber is because I've noticed that the outer edges of all 4 of my tires have been wearing out considerably faster than the rest of the tire.

But my outer edge was almost bald compared to the inner edge after 16k on the stock RE050A. Alignment should be oem spec unless something is not right. Haven't gotten the alignment checked but will do after I install coils and whatever else need be near the end of the month.

As a cheat/penalty, carry an extra 40-70ibs in the rear. Of course strap whatever it is down as best as possible. as far rearward as possible as well.

You don't have to burden yourself with this practice indefinitely, but just enough times to gauge how the tires react to a slightly rearward bias change. The GVWR accounts for a load range of up to about 200ibs. And additional load on the rear can keep the tires from sliding and scrubbing the surface. Downforce

This way you can adjust your alignment and get ride of the crappy factory diff. This and seat time will improve your lap times with least amount of money spent.

Several people have gotten away with using the factory differential at the track including myself with several cars. Of course there is a limitation, but adding a new one comes with increased complexities in both drive-ability and wear. In most cases using the standard setup up first at the track with different tires gives one a better base line for expectations and measurements against mechanical and geometrical changes.

Go back to the G37 forum where you belong.

I wasn't at all trying to make this about me. I just like sharing and debating good ideas. But i'm not gonna hijack OP's thread to get on a personal debate with anyone, certainly something not relevant to the original premise.

You guys already shared good info, i see no reason repeating the same stuff. I'm sure their were other things OP wanted to expand on, or in the case of a future reader looking at this thread.
