Your back tires does anyone here lower the pressure for some traction? I put mine to around 28 27 anyone go lower or higher?

 

Depends on the tire... My MT DR I put down to ~17psi..

 

I've had my dr's down to 13 psi before..usually at 15 though

 

I usually take my street tires down to 22-23ish

 

18-19 on my bfg DR's

 

guys, just a fyi, if you start lowering the tire pressure on your street tires you will end up losing some contact patch due to the tire "cupping" along the center of the tread.

 

I've always run:

- 28-30psi for street tires

- 16-20psi for drag radials (depending on track conditions)

 

I leave my 315 streets at 37psi. Once I get Dr's then I'll start lowering it.

 

yea i gotta get traction somehow..best time was 13.9 idk what it is with that track everyone seems to get lower a ******* z06 got 12.9 a c6 z06 that is.. and my 60ft best was 2.3 idk if its me or the track because its pretty funny i can almost spin 3rd not chirp but spin 3rd on the track but on reg pavement it just chirps 2nd and 3rd

 

yeah i used to do that also untell i talked to a local drag guy around here and he was explaining how i actually lose tracting due to them being solid walls so they dont actually bend for traction where as a slick has the bend wall so it always grips

 

the best thing you could do for traction, at the track, is to unhook your front swaybar. and if you are spinning that bad, try leaving in second. see what that does for ya. when i had a 4.56 gear set in my car, 1st gear was useless. i dont know what gears you have though. if you wanna get sneaky, try a little bleach on the tires right before you "put a little heat" in them. though that may be hit or miss on treaded tires.

 

Thats weird, are you using the waterbox? I wouldn't on street tires, just drive around the box and do a small dry burnout. than stage. Good luck

 

i usually lower my street tires to around 25 PSI due to alot of wheel hop ...that usually gets rid of the wheel hop and i have pulled 2.0s on street tires with a conservative launch...

 

15-17

 

12-13psi on my ET Streets. Cutting 1.58s at the 60'

 

I ran 22ish PSI in my Nittos when i went for my first time - they worked..just the driver mod was pretty bad.

 

40 psi on street tires (way back when), drive around the water box and do a real small burnout just to clean the tires off (don't heat them up).

20 psi on Nitto 555R drag radials, drive through the waterbox and do a long 10-12 second burnout to get them nice and hot.

20 psi on M/T street radials, going through the waterbox and doing a five second burnout to get them warm/mildly hot.

I've gotten 2.0-2.1 60's with the street tires while feathering the launch a bit. I've gotten 1.7 60's with the Nittos going full throttle off a straight idle. I've gotten 1.6 60's on the M/T street radials by brake stalling up to 2,000 rpm's and flooring it on green.

 

Yep, taking off sway bar helps alot... I do it ever time at the track. No issues with traction on my 255/50/17 MT DR...

 

how hard is that to do?

 

about as hard as taking out a bolt
