What are most of the low 6 second cars these days? Bracket cars stepping up? Four links or hard tails? 270” or longer or typical 245” cars?

Kurt Damron if opening Undercover back up.
That would be my first choice.

My 248 Duel shock swing arm UC car would hook down a dirt road. It worked just as good with the 2500 hp blower motor going 6.0x at 235 mph as it did in bracket form with a Rons injected 565 going 4.70s at 145

I have a Danny Nelson 252" Car. Drives like a Caddy... 4 link

I have a one off 275" hardtail with double slip joints...works for me. last car was a Bos 257" double slip joint car. Same deal, worked well.
