hah , I would guess you are quite a bit passed the whole green thing , and could probably make use of 1/4 inch of more contact patch ! That CCW idea actually sounds great! in the long run I think it would be cheaper to pay more for a wider 17 wheel . then go with an 18 and pay more for tires ! 
Would love to get some wheels etc.... BUT I just spent 5200 on paint and a cage that I must now spend money to have remove and reinstalled blah blah so I am not going to drop another 3k on wheels at this time no matter how much faster it will make me.

Yep, super excited and can't wait to get back in that seat again after the cage is redone and the cooler setup is in place, both of which will give me confidence to put the hammer down

Bars not symmetrical in any way shape or form and bent in various places for no particular reason
Bars not safe or right over my head touching it
Cross bar too close to forward movement
A pillar bars too far off A pillars and there's even a large difference in how far away each bar is from each a pillar
Bottomline; you name the problem and this cage has it LOL

Cross bar too close to forward movement

I'd actually be pretty interested to see what the difference would be if I pulled a 255/35/18 over my 18x10's instead of a 285/30... though the Hoosier 255/35's have apparently been outlawed for handicapping purposes at time trials, because they are so large, so mitigates the value.
Fritz, a 255/40/17 would be shorter, and if it spread out to nearly as wide as the 275 on a 9.5" rim, that would be a dream for time trials.
I've always noticed that the Japanese Time Attack cars always run 255's, and as I recall, even Pettit's wide body SpeedGT car ran 275 rears (as mandated per rules).

but it's right in my wheel-house with the Nittos that I love.
Are you having troubles running a 275/40-17 in the front? I have problems rubbing the fender liners with my 255/40s and haven't tried 275/40s up front for fear of how much worse it'd rub or I'd have to raise the car (25.3"-ish ride height currently).

If you are truly "Back in the Saddle", you need different music:

Yes, it is the standard width measured. but you want to basically stick to the wider range of the widths. A good rule of thumb is a wheel width, bead to bead, to be wider than the tread width.
Michelin engineers make this claim in their porsche presentation.
Slide 34 and on
www.cb-racing.com/PilotCup_Presentation.PPT
they are basically saying that running a 245/40/17 tire on a 9.5 wheel will provide less understeer, more grip from a mechanical stand point and provide better feedback and turn in.

High Performance Wheels
Wide Rims
If you're opting for high-performance tires, you'll probably want to include some new wheels to enhance both appearance and performance. To assure the right fit, you'll need to make sure that you've got the proper replacement wheel size, dimension and load-carrying capacity.
Narrow Rims
Result in an improvement in ride quality, but may sacrifice some of the tire's ultimate performance capability.
Increase your vehicle's stability, steering response and cornering capability. A Yokohama quick tip—use a rim width which is 90% as wide as the tread width of a performance tire for street driving. This will provide a good balance between performance and ride quality.
Mid-Range Rim Widths
Provide a balance between handling capabilities and ride quality. The wheel's width influences handling and ride quality. Always choose a rim width within the range of the tire's acceptable rim width specification.

I had forgotten to make a small point regarding this . you are comparing apples to oranges street tires have a much softer sidewall so more stretch stiffens the sidewall and lessens the flex under cornering ,
Now as I understand it . Rcomp tires already have very hard sidewalls . so you can fit a wider tire onto a narrower wheel and achieve same sidewall stiffness . since there is no compromise on a Racing tire to be comfortable on the street as there is on a street tire , like that of the S2k , or Porsche cars mentioned above .
If you look at auto-x cars before when stock class was allowed Racing comp tires they would run the widest tire they could fit even if they got buldge I made the same question regarding the sidewalls and I was explained that it wasnt as prevalent . wider tire always = better times .
I'm not saying using 275 on a 11 inch wheel will not be quicker then on a 9.5 ,
BUT i believe it will be quicker then a 255 on a 9.5 ... As its a very commonly tested subject in autocross .
P.S. I understand i am also comparing apples to oranges trackday / autocross

At one point I was 26 or more inches but currently around 25.5. However with the lower setup the LF rubs like crazy and the LF should go lower to really have a good corner weight but clearly I can't lower it anymore.
I know that I could do so many things that would allow it to go faster and I eventually will because the new cars coming out are VERY VERY fast and there is no motivation like competition so you can bet I'll be making some changes in the future in order to compete.
Simple things I could and should do:
Get that new fast spooling borg warner turbo
Big GTC wing from APR
Improved wheel and tire setup as discussed
New or rebuild my coilovers
Improved front brake ducts (piper may sort that out while they have the car)
Lower 5th gear
etc....
Take out the HLs, wipers, passenger seat, etc.... to remove weight and turn the boost up a tiny bit and look out UTCC here I come hehe
PS With all that said one advantage of driving a car for many years that hasn't changed much is the satisfaction you get from knowing it was you and not the car that lowered your lap time. The very 1st track event I attended with this car back in 06 I ran a 2.08 and now I'm running very close to 2.02s and I believe a low 2.02 is just a set of fresh tires and a nice clear open track away

Glad to see you out there again. Can't wait to get another ride with you now that it is at full power again.
Quick question:
Would the new Banzai Racing Transmission mount benefit your setup? Mainly with the PPF destruction you've experienced, lol.

However as Pete pointed out a 255 40 is not as tall and therefore I could change the setup or ride lower or improve the corner weight....... and I may still give the new toyo race tire a chance they make good rubber or even go with the RA1 as a warm up tire/race tire in the 255 40 size. I have 12 9.5s now and I will use them all, I'm hell on tires LOL.

Fritz,
Try to post pictures of the diff cooler setup. I personally have never noticed any symptoms of my diff overheating but still would love to look into a cooler also.
Even on hot days, my diff has never leaked and my fluid isnt really that nasty black. I have a 1.5way carbonetic carbon diff also. Maybe its the type of track? Or maybe I am not examining the fluid correctly.
I use Motul Competition Gear oil 75w-140

Also if you want to see pictures of my brake ducting shoot me a PM. it's pretty simple backing plates and hose routed thru a trimmed under panel, but seems to work well so far.

I do think this really depends on the tire. Hoosier's and BFG's are substantially larger comparatively than the Hankook's or Kumho's in the same size. lOOkatme is suggesting a slight stretch (nothing like the "fitment crowd" uses though). I haven't tried it, but I do know some TT drivers who do run stretched tires. Granted, most of their reasoning is more due to costs and classing (i.e. they already have 17x9 wheels, but they can only use 225's for A6's based on their available points). I will say these drivers are extremely fast (2nd, 3rd in nationals) so it can't be a bad thing.

Not sure what tracks you go to but if lap times are sub 2.12 VIR or Sub 1.24s at Summit I'd worry a bit and give it some thought.
I've contemplated the 255 squared setup because it's be nice to be able to rotate front/back. Even with my 255/275 combo I still kill the rears first.
Also if you want to see pictures of my brake ducting shoot me a PM. it's pretty simple backing plates and hose routed thru a trimmed under panel, but seems to work well so far.
