Reply to "wheels and tires"

Thanks Daniel, David, Will and Doug! The wheels absolutely change the look of the car from before. Will, the wheels are 18x10"fr and 18x13" rear and my tires are 255/35/18 and 335/30/18 Michelin Pilot Sport 2's. My previous tires were Michelin Pilot Sport 2's as well in 255/40/17 and 335/35/17 which gave an outside diameter of 25.2" fr and 26" rear. I wanted to keep the same ride height so I was able to keep the same widths but drop the profile and end up with the same outside diameter. I wanted to maintain the slight rake rear to front. I also thought it was important to have a larger sidewall height in the rear to give the car that muscular look without having the rear sidewalls anemic. I am not sure of the backspacing? I measured them but I don't know if I did it right? I had adjust these with machining regardless.
I had a Pantera vendor direct me on the measurements they wanted as I was going to have a set of dished 10 spokes made before I found these. At weighted ride height I measured from the ground to a repeatable spot in the bottom of the lower A arm for ride height. Then I put the car on a lift, removed each wheel one at a time and placed a jack under the lower A arm and lowered the car back down to full weight using the jack to support the a arm until it was at the same ride height. Then you drop a weighted plumb line taped to the fender straight down to use as a perpendicular reference for your fender lip. You then measure from the center of your hubs and rotor hats to the plumb to give you how much depth you have for the wheel clearance. Do this for each wheel. Mine was different all around. I hope I am explaining this correctly?
I still am toying with wanting 19" rear wheels but It may be too large for the lines of my 5S body? The only sizes I know of is Michelin PS2 in 345/30/19 but that is about 27" od and Pirelli makes a 355/25/19 which is a shorter od.
The only thing I would change on mine is I like a "Soft" lip on the wheel instead of the stepped lip. That gives a bigger center section and longer spokes. Of course then you have to go to larger rotors to fill the wheel. Always an expense! I really like Alex Stoffer's new wheels http://s461.photobucket.com/albums/qq337/alexstoffer/ and the thread on the PIBB is http://pantera.infopop.cc/eve/forums/a/albumcomments/f/3350045562/m/9470035475
Those have the soft lip and look more modern to me. Of course he waited a year and they were expensive as well.
Will, I am sure you have been waiting and frustrated as I know Larry is with Kodiak. Please keep me posted about your 19" as I may want to try a pair for the rear if they ever do a soft lip.

Warmest regards,
Don
