I'm running the same tires as you with around the same hp as you, but with 4.10's and a 6-speed. Anything less than a 2nd gear roll and I have no traction

high impact

TGEAR, I have seen a lot of guys running these tires. It appears these tires need a lot of heat to hook well with a stalled auto.

HCI, I wouldn't run radials with a 6 spd - I have never seen anyone have any good results with a radial and 6 spd. If you want to hook well stick with a bias tire.

As said above you need to heat these tires ups substantially, for the best results.

I agree for the most part.

Im running 397 whp (3.42 gear) on motor and hook on the track with so so prep. Hooks well on the street however. On the 150 shot I can hook on the street surprisingly well but have zero traction at the track even with prep. I'm talking about I can do a 3-5 second burn out and still spin at 100mph on spray with the 555R's.

I recently bought some 255/50/16 Hoosier drag radials and hook like a **** on the street or track on the 150 shot. This is without a burnout, just a short haze to clean the crap off the surface of the tire. Hope this helps.

Get them hot. By hot I mean 2nd gear burnout at a decent RPM for 7-10 seconds.

If you made 430rwhp through a stalled auto they just might not be the tires for you unless the track is prepped excellent and there are no street tire cars running before you.

I sometimes spun those tires with 2.73s and a stock stall. With 3.42s and a 2800 stall traction was very hard to come by.

I agree with what most of these guys are saying, but I think we're overlooking half of the problem.

Fix that wheel hop, get LCA's and relocation brackets.

OP... Any suspension mods?

Get a good burn out with smoke. Track prep plays a big role! Nittos 555r took me to 11.30's

I did 1.6 60 foot times wth those tires.

My best 60 with them was a 1.69 but it was hit or miss whether I could hook, stock suspension, well prepped track.

Nit to 555r, my first exp with drag radials, bI'm pleased. Street tires roasted at anything under 30. These grab from any speed even from a stop. Only timI've got them to spin is when the n2o hits, spin like a shift kit hitting tho, and grab right away. Track grip was good on motor. Small burnout.
