  1. Pirelli has lowered the price of the Trofeo RS

    Very good question, Sofa King. I do not have the answer. Does the grip drop after one year in a warehouse? I thought they would be good for two years, but I am no expert.
  2. Pirelli has lowered the price of the Trofeo RS

    This is the original Dark Horse handling package tire. The rear, 315, used to be about $780 It is now 600 bucks https://www.tirerack.com/tires/tires.jsp?tireMake=Pirelli&tireModel=P+Zero+Trofeo+RS&sidewall=Blackwall&partnum=13YR9P0TRS&tab=Sizes The front (305) is lower priced, too, but is a...
  3. Rear tire size

    On my car, the track set up will actually increase by a half inch, to 11", on the front, to match the rear, rather than decrease what I can install on the rear. I intend to have tires with tread in the 10.5-11.5" range, as well, the same on front and rear. If I could run 12 or 13 all the way...
  4. Rear tire size

    911 Porsche has drastically staggered setup, as does Corvette and supercars The Porsche 911 GT3 RS, probably their best all around track car, has 275/35R20 tires on the front axle and 335/30R21tires on the rear axle.
  5. Rear tire size

    You can fit larger wheels and tires more comfortably in the rear than the front. My Dark Horse handling package came staggered, 10.5/11 and 305/315. I think the standard Dark Horse and the GT Performance Package are staggered, as well. I will probably remain staggered for my street tires...
  6. Rear tire size

    295/30R20 is exactly 27" tall, the same as stock, and can be used on a 10-11" wheel.
  7. Rear tire size

    Oh! I missed that they are different front and rear. So front is only 27" I would try to get as close to 27 and 27.7 as I could get so that your car never knows the difference.
  8. Rear tire size

    I hope it works out for you. I would hate to lose some functionality or have my car behave strangely due to tire diameter.
  9. Rear tire size

    And they recommend a 9-10.5" width wheel. OOPS! I just noticed I wrote 19. That is supposed to be a 20. I corrected it in bold in the quote above. Sorry for the typographical error.
  10. Rear tire size

    I think my other post was made while you were posting. On the Dark Horse handling package, the front tire is a little taller than the rear (Trofeo RS). If it had not been for the diameter listing online at Tire Rack, I would have never known. Nevertheless, unless your front tire is already...
  11. Rear tire size

    I don't know what width front wheels you have, but a 265/35R19. OOPS, I meant 265/35R20 Pirelli PZ4 is 27.3" diameter, so the front and rear would be almost exactly the same height. Frankly, I would have gone with a wider wheel and a 305/30 front and a 315/30 rear. That is what is on my car...
  12. Rear tire size

    That is 3/10 of an inch. Only half of that difference in diameter is at the top of the tire, at the wheel well, so 3/20 of any inch. That is barely an eighth of an inch. You won't even be able to see this. You would not be able to notice even if the original tire was there for comparison...
  13. Rear tire size

    What is the stock diameter? 315/30R20 is a tall tire.
  14. Rear tire size

    Is there no 30 aspect ratio available, 315/30, instead of 35?

    The post was mocking the very idea, but you seem to have read it in the opposite manner.

    Forcing manufacturers to produce cars with 3 cylinder engines that weigh 1200 pounds would save a lot of gasoline. It would be a "proven . . . gas saver over the entire population."
  17. KPM Fuel Systems @ PRI Indianapolis

    Are you going to do "self fitment?" 🤔
  18. Auto Start/Stop killed by EPA rules deregulation

    Huh? 🤔 Federal government mandates are what drive innovation, technology, and competitiveness with Chinese car makers? 🤭 😜
  19. Auto Start/Stop killed by EPA rules deregulation

    Do any of the Dark Horses have auto start/stop?
