Take your Honda Civic, or whatever you drive daily, randomly "adjust" the suspension and then tell me how well it performs at high speeds!
Point is that this is not an inherent flaw of a GTM. It is a flaw that builders are not setting them up correctly.
Set a stock GTM up correctly and it will beat the pants off of just about anything. If you then want things to be more comfortable in the 100 MPH range because you really think you will be spending quite a bit of time up there, then start making all these performance changes.
I see nothing here that I wouldn't want to do to my daily driver to get more high end performance out of it.
Does this mean that FFR built the GTM wrong? NO!
Does this mean that Ted's products are not needed? NO!
It means that we build these cars for different purposes and different items are needed depending upon what we are building for, and no matter what you are building for, if the alignment is off, then the car, whatever car you have, will not be fun or comfortable to drive.
I do believe Ted is trying to address both issues with this thread. He is helping builders out by suggesting settings and showing you how to do the alignment, at least I think he is going to, and he is also offering items to help the GTM at higher speeds perform better. Same as any local tuner shop does for the ricers, but Ted is focused on GTMs and more meat than bling as far as solutions are concerned. At least that's what I understand from working with the guy.
