Don't missunderstand, I'm not questioning your decision, I believe Michelin's are the best tire out there and was poised to pull the trigger on that tire. I just trust Marc's opinion. I have too much wheel spin with my particular setup to keep the drive enjoyable.

Marc's reply,

In general the NT 555 is a good choice for the front and the rear. The rear tires will slip a little in first gear at full throttle.

If you don't want any wheel spin use the NT 555R in the rear. They will not slip on the street with 500 hp and 4.10 gearing when the ambient temperature is over 50 degrees. I like to use NT555 in the front and NT 555R in the rear of my car. The car accelerates the fastest when the tires are sticking.

The NT555R has a about 25% less thread depth than the NT 555. The compound is soft. They wear out in about 15k miles. However, they are not expensive.

For best handling in turns use NT 555's all around for balanced grip from front to rear.

Best regards.

Marc
That is an interesting statement " no wheel spin" I have MT 345/35/18 drag radials and I could torch the hell out of them if I choose too. I am guessing you are talking more of an easy acceleration.

The Shelby wheels will have Toyo RA1 "335/30/18 on the rear and 275/40/18 Proxes T1R don the front.

I agree with your thought - Marc does not baby his car, so I'm gong to take his word for it. I'll let one know when I get them installed. I have terrible wheel spin right now, even when shifting 1-2 or 3-4, I go sideways it not a straight line. I drive with Trac Control off - cannot stand the intervention. Old school I guess, just do not like it on.

Bill B beam plates will help with the sideways and yes, Marc does not baby the throttle

Wow, on e-bay, CWO had two sets for $480, cost me $506 for the pair, shipped. I should have scooped both sets, somebody would have bought them, or i'd have had a spare set. Seems like at that price, it's a no brainer, buy the F1's. 'Cept they're not available.

I couldn't get mine to spin at 4500 rpm in 1st gear with brand spankin new rubber either unless it was real cold out or I unoaded the rear a little over a bump.

Be careful of cheap tire prices. Now, I always ask
for the DOT manufacture date in an oval on the sidewalls.
Very rarely is a "cheap" tire less than 10 years old.
