    Default Charles Ng Buttonwillow 2:03(Stock S2000 CR)

    Enjoy the video!

    2:02 is definitely doable on a better weather day. Drove a few buddies cars and datalogged for them, all in all another great day on track!

    Actually its 255s around, we swap over the tires at Rising Star Motor last minute when we decided to do the CR attack. So the front and rear are different brand. (same size tho, haha) Front tires are RE-11 and rear tires are NT-05, the rears get greasy after a few laps under the hot weather yesterday. Honestly, not the fastest setup for time attack as it is a bit oversteery, so I figured that 235 fronts would be very similar lap times. However, if we had RE-11 all around, it would have been a 2:02 easy.

    How would you compare the RE-11 and NT-05 to comparable tires? (AD08, Z1SS, RS3)?

    Its funny cos I had the chance to drive all of them in different cars in the last couple of weeks!

    I would say for rain performance, RE-11 is superior to NT05 and RS3 by lots. I have driven them all very hard in the rain and RE-11 gives you the very predictable feel just like when the ground is dry, both NT05 and RS3 dont really like the rain and they tend to understeer when you have them in the rain.

    For dry performance, I would rate
    RE11 90pts
    AD08 90pts
    Z1SS 85pts
    RS3 80pts
    Federal RSR 75pts(cheap)
    NT05 75pts

    I havent driven them back to back in the same car, but from the feel of it, I can tell you right away that RE11 and AD08 are one notch higher for time attack and track abuse in terms of grip level and consistency. Others on the list either have high grip but inconsistency or the grip level is simply not up there. However, Z1SS are great tires for the money in the mid price range, very predictable and the tires like to be driven with less slip angle.

    Hope the above info helps.

    I very much appreciate your feedback.

    Would you say the setup on the cars affected your ratings of the tires at all? I actually really like the NT05's I have on right now, but if you rate them the lowest, then I'd be very tempted to get some Advans

    Now if only I were that fast....


    I know the RE070 is not very common, but have you had a chance to drive on them?

    Better setup like suspension work definitely can extract the max perfromance of the tires but in this case wont affect my ratings.

    In fact I did drive the RE070 and RE050 before in Stock S2000s. OEM tires are surprisingly good to be honest, usually only 1-2 sec slower than aftermarket performance tires on a mid size track like BW

    Go with Advan, cant go wrong for driving fast.

    Charles, where do kumho xs's rank on that list to you?

    also z1's less slip angle meaning they break away quicker?

    Less slip angle for maximum traction is what I am thinking. Correct me if I am wrong.

    Even my friends call me the street tires specialist, I honestly havent driven the Kumho.

    Means they dont like to provide the driver the "forward sliding" grip, for example the process from grip to drift is less linear or less predictable(not exactly but cant have a better way to explain). Some tires can do that better than others in that subject.

    impressive, much more precise than your driving before, you don't drive like this if you had a car like Justin's,

    with the right alignment (more rear camber and toe-in) to stablize this car, you could drive this car at 2 min flat

    you finally made my words come true that stock CR is fast, nobody wanted to believe me!

    however, this oversteery setup is probably perfect on tight touge!

    Charles,

    You drove my CR with non-stagg NT-05's...did you hate them that much?
    Also, when is your Formula-D event coming up?

    Charles,

    Did you and Justin thought about swapping the NT-05 to the front and the RE-11 to the rear?
    It might have been a whole different story, 2:02 for sure if not 2:01, if u ease the oversteer a little bit since its killing your riverside track out speed, which is the most important segment of bw...

    I think my exit speed in Riverside was over 100 or sth, which was good. I think its not much time to gain given I was flooring it and the momentum was moving forward with minimal to none correction, plus the most important segment should be the exit speed of final corner not riverside. If anything to go faster at Riverside, its not just swapping tires, its aero grip at that speed IMO.

    The other thing is if NT05 in the front, it may induce understeer at sweeper and other places which also lead to important segment.

    CR wing is good though, it doesnt change too much of the Stock S2000's twitchiness, which is why S2000s are fun to drive.
