Our UK friend was using an entirely different kind of spacer / adapter then what has been referenced here. Completely unsuited to heavy cornering loads. But hey, don't use any kind of spacer and be safe!

Wasn't really referring to you, but :thumbsup: A I love to tell my wife: don't chase the rabbit!

And we're on our way to another thread derail . . .

Do you have any details about that mess, or are you just throwing the picture here claiming that it demonstrates some universal truth about spacers? Can you identify the fundamental differences in that mess with what we're talking about here?

No. I choose not to. And, it's a false equivalency in any case.

Pure ignorance and lack of experience. Please do not cloud up this thread with your lack of knowledge or experience.

That statement is one of ignorance. If you believe that price alone dictates quality and somehow guarantees that a wheel won't fail, then this conversation is not for you.

Believe me, I agree with you. It may be apples to oranges, but I'm used to spending $175 - $250 per wheel for my BMW race car. Whole different ball game with this platform, and I haven't really adjusted yet . . .

That's right, uneven wear becomes an issue and affects performance. The thing to understand is that this is somewhat of a penny-pinching approach to track time, and trying to maximize the cost-per-use ratio. Performance tires are expensive, more so for the GT350 sizes and compounds we're...

If we try to use a 55 offset wheel on the front, the stock studs will not work. You can buy a spacer with studs, but I would prefer to replace the OE studs with an ARP wheel stud through the hub, and then mount a properly machined, hubcentric spacer and wheel on those studs.

Stock non-R rears are 19x11 et 62. The R rears are 19x11.5 et 55.

The "typical" forged wheel formed for track-dedicated use runs around $1250 - $1500 on the lower side of cost. That's a wheel forged from billet, designed to keep a tire and air pressure intact after some degree of impact (bend, not break), machined to high tolerances and low weight without...

I don't know that directly, but you should be able to find the answer on a site like Tire Rack, if they stock that tire (haven't checked). In this case, I'm looking a the PS2 in 305/30.

Sorry, but tire rotation IS a fact of life for those who want to max the usable life out of their track tires. Tread depth is only one factor here, and as was mentioned in direct response to your post, tires do not wear evenly on a given road course.

Thanks. That's a great price for a fully forged wheel; I'll put some questions to Paul. Was there a reason you didn't opt for a full square setup?

I recognize that there are a lot of wheel threads, but I want to drill down to some discussion about running wheels with the same width and offest. Or, not . . . This is a track use focused issue, and the primary (if not the only) value of the same offset is to be able to rotate each wheel...

Given the profile, dimensions and front undertray, jacking on the subframe really isn't an option. If you want to lift the front end as a single operation, custom ramps are the best/easiest option. The GT 350 nose will not clear a typical auto parts store ramp. Jacking on a pinch weld is easy...

Staying out of the side line discussion, I'll have to agree that if we're talking about a GT350 and a power cut (TC) is turning on as described by the OP, then something seems amiss. While in track mode, I have to get the car pretty out of shape to engage the power controls, or be in some...

If the intoxicating sound of the exhaust in sport mode at full song ever lets you go . . . I think you'll find that the GT350 handles its weight very well. With the OE chassis tuning and suspension set up, under steer is negligible. As mentioned, the steering is a bit numb, but very well...

Proper initial heat cycling of a competition compound tire is a must if you want to max the number of heat cycles a tire can offer. There are diminishing returns with less aggressive compounds, but they're still there. The Cup 2 (in my opinion) can benefit from break-in heat cycling. I don't...
