So I've gone to the drags 3 times in the last 4 weeks.

Started off with PSS rubber on the stock 19s (265s) and got an 11.83 best (4 runs)

Went back the last 2 weeks with R888s. 3 runs each week and got 11.83, 11.86, 11.91 the first week, and 11.83, 11.86 and 11.80.

Best so far is 11.80 but can't seem to crack the 11.7s.

I thought the Toyo R888s will shed more than 0.03sec off my best time. My 60ft is still around 1.82-1.83.

What can I do to get the time down (without a supercharger).

I'm considering getting lightweight rotors but not sure that will save any time.

Opinions? Options?

Race fuel and race tune Charlie

Try that should get u too 11.7

charliekay

I thought about that, but I want to try and see how quick I can go with full trim and pump fuel. I can get MTs or Hoosiers, race fuel, take out headrests floor ats etc.. But I want to see how quick I can go using daily driver fitout.

I think if I can perfect the takeoff then I can get there. My 60ft should be in the 1.7s with the R888s.

Ur nearly there bud

Try again next week

I u get any tyres get mts

Wait till November.

I'm in Australia so we are in the middle of winter now. Though our winters aren't anywhere near as cold as winter in some places in the US.

Tonight was 13 degree Celsius. 55 degree Fahrenheit.

Are you spinning off the line?

khmergod

Lol at 55f. Even houston can drop below freezing time to time. Ou summers can hit mid 100f. It already did this year. I'm waiting for winter to let the beast out.

charliekay

Nope, I brake at the line, rev to 1500rpm, release brake on green and ease up to full throttle.

Merc63

No way to be drag racing and easing into the throttle. You should be WOT right off the line. Get drag tires. Its useless to race without them and attempt to get a good time cause you wont.

MT ET Street Radial 265/40/18? Are these better than the R888s?

I read other posts saying not to get radials with an overall diameter more than 25".

mthis

Get your self some Mickey tompsoms and u will be into 1.7x 60 foots and also go WOT as soon as u release the brakes even try to do it at same time as u releasing brakes.

Are you using S or M?

charliekay

S mode (i hit the left paddle shift so it brings up D1, i believe that it the equivalent of S+ mode in the prefacelift cars).

I also have ESP off.

ideally you dont want radials for a drag tire. The bigger the sidewall the better also hence people running 16" wheels and downgraded brakes. If your not spinning than no tire will improve anything, there is no missing traction to give back.

mr747

I have never heard that????

Why don't u use m mode

charliekay

Consistency. I run the same time over and over.

M mode might get you a little quicker if you get every gear change perfect. Miss one but the slightest bit and you lost any time you would have gained from the 2 other perfect changes.

jrcart

What air pressure where you running? Even though they are not DR's they still like low air pressure, I used to run 22psi in my CLK BS on the stock Pirelli Cors'a and could manage consistant 1.70 60ft's on them and even some 1.6X's once in a while which is very very good for a stock tire.

Welcome to my dilemma I had for ever! I have no idea how ppl in USA crack 1.7 60fts. I managed it once and bam went 11.7. I've ran 2 11.7's. one with 1.7 60ft and the other with a 1.8 60ft. I tried the r888 and mt 245 which is what I now have and no difference. We can't come pare our times to USA times as they simply run faster over there. To get the best times in oz go to Heathcote in Vic. You can try lightening your car, but all that stuff you said will only make a 20kg difference. Try m mode too. I find my best times with s+

Aren't you trying to break that consistency? It seems to me you've discarded every idea given to you, including one related to your driving. How do you expect to improve then?

charliekay

I tried them between 16psi and 19psi warm, maybe I should try again at 22psi.

If I get the MT ET Street Radials what PSI should I be running?

I will happily try M mode, at no point did I say I wouldn't. Though there are alot of people here who have tried all variations and found S+ mode the best as like I said previously, if you miss 1 gear change by the smallest bit, early or late then you will lose any gain you made up and more. The problem with the C63 (not sure if this is fixed in the facelift models) but when you hit the paddle to upshift it is not instant, meaning you need to not only shift perfectly, but bleep the paddle shift at the exact point to take into consideration the delay. It is very difficult to get perfectly.

The only thing I said I didnt want to try at the moment was race setup (gas and drag radials), my aim was seeing how fast I could get it on street trims, day to day.

But by the sound of it it sounds like I am doing the best I can with my current setup. Might need to try some MTs

RNS-11Z

Honestly, don't waste your money on mts I did, made no difference! If your 60ft is 1.8 your not wheel spinning.
Try race gas, try lightening your car.

charliekay

I wheel spin if I give it full throttle, that is why i am easing into the throttle.

Maybe MTs might get me a bit better traction off launch.

RNS-11Z

In that case try the mts.
