I would go with a 255X17 front tire minimum, A 275 might be possible if your car isn't super low. A 9" or 9.5" rim is needed for the 275. I don't think a 295 is going to fit inside the wheelwell and turn without hitting, it would take some major surgery. Another problem with the stock sub is, there is a fair amount of scrub radius (depending on wheel offset) that makes the wheel move forward and rearward a lot when it turns.
How are you going to run weight jacks on all 4 corners and still have shocks?
Only moving the engine a couple of inches isn't worth it in my opinion. Too much work and too many changes to gain a couple of lbs off the front wheels. Better to focus on making the front end lighter with other lightweight components.

==================================
David:
Thanks for your response again, I really appreciate you taking the time to write. You have been around these cars so long, your kind of like speaking to an oracle.
In any event here are the answers.
I have the two brands because the DA Spax Shocks are new and they came with the 3-Link and were valved for it. I have the Penskes on the front because they are shocks I can use forever and re-build and/or upgrade if I ever wanted to, and I can have them re-valved easily. The Technology of this brand is amazing. I know they are outrageously expensive, but the adjustment is decently easy for me to do with my replaced right shoulder. When talking to Tyler, he said they were overkill to a point, but the quality of the shocks and tune-ability is a fairly big factor. (FWIW: I have bought so many things for this car that are technically overkill, that it has been rather funny) I do have an extra set of 3-piece Kinesis that are 17X9.5 that will hold a 275 very easily, along with a matching set of 17X11's. At this point I really want to Run the Mini-Lites as I almost Never see a set and I always loved them on the Trans Am cars.
I have the 245 mm for the front so I can run a matching set of Sumitomo HTR Z Tires. I am expecting to go through several sets taking lessons and they seemed to be the best bang for the buck in the 315 mm size, otherwise I would have the 255 mm.
The weight jacks have been installed to allow the car to be easily balanced with me in it, and to making it easier adjusting the ride height (Remember my Shoulder), hopefully without changing the efficiency of the suspension.
When I saw these set up, while not inexpensive by any means, I thought they would be worth it to me to make things in general just easier to do some adjustment on the car. Since my Crash, anything I can do to keep from working so hard doing simple task, and to keep the level of my frustration down. They were $900 for a set of 4 not including installation, but I can adjust the rear weight and ride height from inside the trunk, and from under the hood for the front. Laying on my back and working "up" is very challenging now.
The books I have been making my way through, talk extensively about getting the car properly tuned for the track, and at the speeds you will be running, plus giving the car correct balance, proper anti dive, anti squat etc. etc. etc. This will give the Tires the best chance of staying in proper contact with the track, and biting into it as efficiently as possible. Once the tires lose proper contact and traction, it doesn't matter how much you spent on everything above them, your sunk. (I know you already know all this, I was just referring to the book so my response might be more readable for other people)
Then you also have the proper aerodynamics (As best as you can) in place as well) I still have to get this in place.
Don't know if any of this makes any sense, but your input on my thoughts is welcome, whether good or bad, I just want to learn as much as I can, and as correct as I can.
BTW: My Mini-Lites are made by PS Engineering. He's a really nice guy to work with, and the Black Powder coating in the center looks great on the red car.
Don't spare any words if you are so inclined, I will honestly try and follow your advice as closely as possible.
Thanks again,
Ty O'Neal
