Looking for non-DR/non-slick 60 foots.
Specifically Sumitomo's.

Just had someone tell me they know someone that cut a 1.7 on SumiHomo's.
Not buying this for a second.
Am I wrong?

 

its been done before I'm sure... the fastest I have seen on a regular radial was some 1.8s

 

Not Sumitomos, but I cut a 1.75 60' on 16" Fusion ZR1 hockey pucks. Can't imagine them being better than Sumitomos. Pretty sure I could better that with practice. Have only made 3 runs on street tires with new 3600 Vig. Got better each pass. Last pass was 1.75. I think I've seen a post of someone cutting a 1.68 60' on street tires.

 

I guess an automatic might do it.

I have those tires on the back of my car now....and it just spins and spins if I go WOT in 1st or 2nd.
Just on my car to get me by....as I hate them.

I had worn 275 Continental hold the road better than lightly used 315 Sumi's.

 

I cut a 1.74 once on some Sumitumo HTRZ's. 275/40/17's on heavy Replica wheels no less.

Been in the 1.7x's multiple times on street tires.

 

my buddies car, goes by silverz28camaro on the board, cut a 1.59 on 245 raptors leaving in second gear with his auto....

 

Seriously time to ditch the M6....

 

^^^ yup i was going to say silverz28camaro he does have a video of it also

 

Brad's car is a unicorn

 

My old 02 zo6 went 1.64 with toyo tires. Took about 30 passes to do this but i have lots of people that seen it . Car went 11.3@ 122 on street tires


It can be done just take alot of driving time and getting to really know your car

 

1.79 and i think a 1.77 on 245 yhomama evs1000, t56 11.6- 122 i htink

 

I did a 1.75 on a kumho ecsta supra 712 back in the day, yet only mustered a 1.9 on a nitto nt 555r...go figure... with a 6 speed

 

I've done some 1.66-1.68 on some 275/40/17 BFG kdw tires...auto car with stall.

 

I know a local guy who has cut 1.5 on some kind of street tire (not dr's). He races in the "street tire" class at the local track. He's got it figured out, I tell ya. My personal best was in the 1.8 range.

 

i went in the 1.8 range on kuhma exta supras (sp?) a few years ago

 

I have done in my old LT1 383 car with no stall or gearing, stock suspension, A4, 245/50-16 Falkens was 1.76. Good Prep is my guess on the time.

 

i've been 1.5x on some 275/65 treaded tires... forgot the company, they were off brand.

i used to race in a true radial class (no drag radials)

after i got done with them they looked nothing like a true radial though

 

255/45-17 Sumitomo HTR-Z with a 180 treadwear get me 1.8's. I run them at 19 PSI with a decent burnout. If the track has bad prep its harder to get them to work.

 

First pass I ever made at the track in my life my car cut a 1.67 @ 7.92 with a gear, converter, long tubes and a tune on FIREHAWKS with stock suspension. They were 18" tires, maybe 285/35/18 and it suprised me so much that it snatched the steering wheel right out of my hand! lol

 

went 1.8s on BFG KDWs @ 25 psi with my old vert m6..

they worked pretty good for non-DR...
