Actually, if you look below your name and avatar on the left you should see a line of green dots. We take away a dot whenever you do soemthing wrong. When you get down to one dot, you're not long for this board.
Oh! Sorry Dan...
A lot of the DOT-R tire manufacturer's tire temperature recommendations are based on a stock vehicle's suspension geometry. When you can get 3 degrees negative camber you can lower the recommended tire pressures. Again, tire temps are the best indicators of proper tire pressure.
BTW... I just noticed my link above was wrong, here's the direct link:

In the latest issue of Welding Journal (published by the American Welding Society) is a comparison of infrared temperature measuring guns and direct contact temperature measuring devices. In all cases the guns read below the test material's controlled temperature. In some cases the guns read over 400 degrees low (aluminum plate) due to the reflectivity of the surface. The direct contact measuring devices were well within 1% of the test material's controlled temperature.
Wednesday night drags? When we were doing OTC last year we finished up at Infineon around 4:00pm on a Wednesday. There were a few drag racer guys watching up finish our laps and they came over as we were putting the Rusty Old Datsun in the trailer. One said that he would never consider doing road racing because it was way too dangerous. I asked him what he drove. He pointed over to an 8 second fuel altered with a leaf spring/I beam front axle and no front brakes!
The real shame is the guy that bought it has the car just sitting around in his garage. Get him to drag it over to your shop and make a nice street car out of it so it will at least see the road again.
It won't work and is just another "feel good, look we did something" pile of junk from Congress. IDs are the least effective form of securing anything.
When I worked at a Loral Aerospace I often had to enter secured areas. For two years I had a picture of Charles Manson taped over my regular picture on the ID badge. The first time anyone noticed is when the Manson picture peeled back when I put it under the camera in a man trap. And then the security guard let me in anyway!
I just don't understand the hot rod world's fascination with the Mustang 2 front suspension. Its better then leaf springs or I beams, but that's about all the nice things you can say about it. A friend runs a hot rod shop in the same complex as mine and I've looked at and measured about a dozen Mustang 2 installs and all of them have worse geometry then the stock 240Z front suspension.
I've done the swap also (http://www.betamotorsports.com). Alex's (SR240)work is really nice and if you're building a street car he would be the best choice. My work is mostly focused on race cars and Amir's swap was done with that in mind. It turned out to be one of the fastest cars around WSIR during the Zcar Nationals last June.
Forget all the political stuff, this one picture is reason enough for me!

Normal race or street alignment settings shouldn't have have a significant affect on tire temperatures. Maybe how you're taking tire temps is a reason they are so low?
Is there a long straight just before pit in?
Are you taking the temps in the hot pits?
Are you having to get out of the car to take the temps?
FYI... the lowest I've ever run the V700s was 25 psi cold. Any lower and the tires didn't respond well and felt floppy. And if you're driving the car right the rear tire temps should be a bit higher then the fronts.
You don't need to tie the rear deck into anything. Any bracing that goes there is ONLY providing fore aft bracing for the roll hoop. You have to tie into the rear strut towers and tie in as far outboard on the strut towers as possible to get any chassis stiffening.
Carroll Smith wrote that article on the StopTech web site and he is talking about racing pads and rotors. Also, part of the article mentions rotors changing shape as a result of being firmly fastened to the hats. I think that can be carried forward to street rotor installations and can be a reason rotors change shape.
The benefits of a bolt-in roll bar or cage in a 280Z will be less then the benefits of the same to a 240Z. On street driven car I do not recommend a roll cage. Roll cages and SFI roll cage padding are designed to protect a helmetted person. An unprotected head will get hurt if it hits a part of the roll cage structure even if there is SFI padding on it.
I missed another holiday! First I missed Respect for Chickens day and now this!

Always remember, at an autocross and on most road racing tracks, handling will get you faster laps times. Bryan Lampe's old yellow 1971 240 is making, maybe, 110hp at the rear wheels yet he turned multiple a 58.xxx runs that day.
