my 2

the alter k is square tube
the LRT is round tube

if i was gonna put one on my car i would go for the LRT

a racing buddy i know "LEE on the board"has one on his duster and it runs 130 mph trap speeds with ease

also another board member "cudadon" has one that i have personally seen run and it is also dead stable at 130 mph plus

the guy who makes them has a mid 7 sec car that he built so you can have confidence he knows his stuff

plus the round tube front looks trick as hell


mendez motorsports did my motor too
last year i went to 4 cc events and won money at 3
sat in the rain at us 131
last time out at rte 66 ran a 10.12,10.11,10.11,and a 10.12 back to back

rads racing heads and mendez motorsports are good friends so you can't go wrong with these guys. i'm sure there is some rads racing heads in my motor.
