Vredestein Sessanta and the 1/4 Track

Vredestein Sessanta and the 1/4 Track went to the track yesterday on my new wheels and sessanta 245/35/19 fronts and 275/30/19 rears with about 500 miles on them. ran some shitty *** times. 2.4,2.4,2.2,and a 2.79 on my last run for 60 foots. first time i've ever left the track early and it was partly due to how shitty these sessantas were hooking. on my third run i did a burnout at the track for the first time ever and managed that 2.2. then on the fourth run i did another burnout and got that 2.79 60'.
the track was not prepped that well, but other people were hooking. i spun on all of the runs. the tires would immediately spin and i had to lift and get back on it everytime.
with this same car setup, i was consistently cutting 2.2 60's on 255/40/18 dunlops which is crappy as hell but i was blaming it on the tires since i had to lift on these 2.2 runs.
i got these sessantas thinking that a wider section width was going to help me. and after the reviews on here and other sites, i thought that the sessantas were going to be a good choice for traction. damn was i wrong.
so how's everyone else doing on these sessantas?

I don't have near the mods as you, but mine hook a hellava lot better than the Kuhmos I had. Also better ride, quieter and pretty nice on wet streets.

Are you kidding me....you're running 19" wheel/tires and are crying about a 2.5 second 60'?!
I think you need to go to drag racing school and get a lesson on what gives a car it's traction......that setup and that tire brand aren't gonna get you any.
Drop it down to a maximum of 18" and throw a drag radial on there. Go to a 17" and really watch your times drop.

yeah, you're increasing the wheel diameter to increase the looks, but that also has the side-effect of decreasing the sidewall height, which prevents the tires from "wrinkling" as much, which causes them to spin instead of hook. not only that, but you're lowered also, which definitely doesn't help traction.
the smaller the wheel diameter, usually the better the hook you're going to get, assuming the same brand/model of tire.
if i were you, i'd just get a second set of rear wheels in a 16" or 17" diameter with some 315-width drag radials on them (or even slicks, since you have an S-60 rear end), and you'll hook WAY better than you EVER will on 19's......
if you ride on rubber bands, you get traction to match

i go to the track like i would be on the street. no point in a drag radial setup when it wouldn't be on the car when i daily drive the car.
vettes do come in 19's although their tires are a 285/35/19 which does have 0.7" more sidewall. i was using reviews from the vette forums more so than this site when i chose the vredesteins. the sidewall on these vredesteins are about the same sidewall as my 245/35/20 nankang tires.
on a stock car, i had the 255/40/18 dunlops and was consistently cutting 2.1-2.2 60's. on a stock car, i had 245/35/20 nankangs and was consistently cutting 2.1-2.2. both with no lifting.
the nankang 245/35/20 has a 3.4" sidewall, the vredestein 275/30/19 has a 3.2" sidewall. there is very little difference between them.
using substitution, i really was expecting the vredestein 275/35/19 to at the very least be comparable to the nankangs which were comparable to the dunlops when stock. but under the current setup, the vredesteins do not hook even though this is the widest section width i've run at the track..
it's definitely possible that the nankangs would also spin on the car's current setup. i'll have to try to run the 245/35/20 nankangs at the track with the current setup to see how they do to determine if it is indeed the thin sidewall to blame for everything. i know that sidewall has a good part to do with the traction but i was hoping a wider section width would compensate for it. i did have the 245/35/20 nankangs on with the rpm trans and a tci 3k stall on a stock 10 bolt 3.23 and did not see any losses nor gain in the 60'.
the car feels solid when i get on the gas so suspension "seems" fine. from what i can tell, power is getting put to the wheels... and tires and track prep are the last variables that affect traction. other lsx cars that i saw were not lifting from what i can tell so i'm under the belief that the tires is where the traction issues lay.
after the track runs, i am considering to get some 17" or 18" zr1's and new tires but i want to see if vredestein tires are the way to go or if others on here are spinning on these tires too.

I think he realizes at this point (if he didn't already) that a smaller diameter wheel will hook up better.
The original post struck me as a comparison between two tires he's owned on the same car/ same wheels with the newer tires giving results less than what the previous tires did. So it was just a review of the tire.
Also an inquiry as to how other people where doing with this tire... looking for more reviews.
So what's up with all these replies about this and this needs to be done to get the car to hook? He never asked that question.

If you are modded and making power drag radials always make sense. That you get 10,000 miles out of them is just the way it is. Nitto makes a drag radial in 20", 275 and a 305. I might be running the 305 drag radials. You save about $100 over regualar radials, but they burn off quicker. You gotta pay to play, or deal with a compromised setup. Just the way it is. Go Nitto DR's and your times should drop to an acceptable level. If you want excellent 60' times change your tire size or get a drag wheels setup.

how would the ultrac sessanta's compare to the ultracs? I am concerned about hooking and dry performance mostly. For the price I think I am sold on one of these.

the rear 275/30/19 vredesteins at 46 psi put down about 7.5" of tread to the ground. at 40 psi, it puts down about 8" of tread. the problem with my specific size vredestein is that it is a narrow tire. my 275 is comparable to a 245-255.
i also compared my front 245/35/19 at 40 psi to an eagle rsa 245/50/16, the rsa puts down 1/2" more tread to the ground.
