The setup that I currently want to run on my FC is 215/50 R16 and 225/45 R17 out back. I need wheels to fit that though...

I'm looking to make sure that I keep very close to the stock gearing (including that wheels), or with this setup just go a little higher on it (numerically lower). After I'm done with the tranny stuff (gears...I want a .852 5th gear and the 4.3 rear) I want the car to be limited by gearing up to 142 mph (using a 7000 rpm redline/shiftpoint). I just need to find some wheels that will fit on those particular tires (any ideas?). I've got everything worked out which is why I have very specific numbers. I don't remember off the top of my head what the frontal area of the FC is (I believe it's about 20 square feet...very close anyway, either way I used 20 and 21 for frontal area and .29 and .31 for Cd to estimate the power needed to reach the indicated top speed). There is a little more to it (like what rpm you fall to when you do shift, and the power you have at the particular rpm to name a few) of course, but that's the setup that I want for my car. If ANYONE has any idea of what wheels will fit (or has found any) please let me know. I've already found the tires (Kuhmo Ecsta 712 Supras...unfortunately I can't find Pirellis in 215/50 R16 sizes ...but oh well Kuhmos are great too, I really did want some Neros though). Thanks ahead of time...


Top Speed
---------------------
142 mph (redline limited)


Tire Size
---------------------
P215/50 VR16 (fr)
P225/45 WR17 (rr)


Gearing
---------------------
1st 3.475
2nd 2.002
3rd 1.366
4th 1.000
5th .852
RE 4.3


Tire Height
----------------------
Stock 24.685"
Front 24.464" (-2/10")
Rear 24.972" (+2/10")


Power Needed
----------------------
Approx. 116-127rwhp

 

Okay here are the official numbers that I will need.

Frontal Area
----------------------
22.997916"


Power Needed
----------------------
133.674-142.983rwhp

I had to find the real frontal area of the car to give you an accurate number. If you add in the 3/4" drop then the number is...

Frontal Area
-----------------------
22.651562"


Power Needed
-----------------------
131.661-140.741rwhp

Once again those number (rwhp) are calculated first using the Cd .29 and then the Cd .31 (the first number being the .29 obviously).

Ummm...feel free to reply if you have any info on a wheel that will fit.

 

Ahhh...finally I have the setup decided. The wheels will be Konig Ziege sized 16x7 up front with a 5-100/114 40S bolt circle and offset, and the rears will be 17x7 with a 5-100/114 40S bolt circle and offset. The tires will be Kuhmo Ecsta Supra 712s...P215/50VR16 up front and P225/45WR17 out back. It took some effort to get the whole thing together but I'm sure it'll be worth it in the end. Anyway the whole deal is only gonna cost me $879.79 for everything including shipping (I have to get the wheels from Direct Tire and the Tires from TireRack). Whenever I do get them I'll let you guys know how it works out . Not sure when I'm ordering though...
