I put a set of pro bracket radials on my car and it doesn't like them I don't think.first pass I heated them about like I would my bias slicks and it blew the the tires at the hit,came back did a shorter burnout same deal.both times I lifted and stabbed it and it stayed hooked.i foot brake and stage at 2,000 conv flashes 3,800,first 2 passes were 19 psi dropped to 17.5 and left at idle it hooked and had best 60ft ever.came back and did same launch and blew the tires off.argh!!so I guess I am looking for suggestions,go back to bias or start spending money on suspension. currently it has super stock springs, c.e. shocks,tubular upper control arms with heim ends,heim end strut rods,90/10 front shocks.car normally 60ft 1.50,when it did hook today it went 1.46.thanks,Sam.

DA shocks on all fours should help a lot.

Time for suspension . I use the 28x10.5 PBR . Only ever run radials on my Satellite . Small block front bars with single sdjust qa1 front shocks , xhd rear springs with caltracs and rancho 9 way shocks . Fronts full loose rear shock 1 or 2 loose from full tight on extension . 18-18.5 psi .
Actually turned them wednesday at a no prep street meeting , dropped rear tyre to 18 lossened rear shock 1 click and it hooked .i am leaving soft at around 2000/2200 .
Oh yeah good burn out no John Force . I hold 3/5seconds once i see smoke in rear mirror and drive it out . Too small burn out it will turn .
This is with the PBR and Hoosier 275 radial
Good luck

18psi and a good tire gauge....They either dead hook, or go up in smoke.

All the more reasons why I run bias plys although some have good luck w/em.............

I use the Hoosier 30 x 9 radial slicks myself. I found that as long as I stage in the grove where all the cars launch it always hooks fine. My suspension is basically all stock other then 3400 SS springs and Comp 90/10 front shocks. Rear shocks are just the longer MP shocks. My 60's are low 1.50's as its usually from 1.50 to 1.52 with a 1.50 best. But is is very consisdent for a radial slick on a car I drive to the track. The last two times at the track all my passes were all within 4 hundreths of each other all day long. Ron

Anyone ever did a back to back comparison on these two types of slicks?

I would try lowering the pressure. I run a Hoosier radial slick. Started with 18#, best 60' I got was 1.24 with 13#. U have to experiment with tire pressure at different tracks.

which 2 ?

The radial will always be faster if it hooks.
