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.
