i would never recommend it for a 350 hp car. especially a street car. especially if you live in a warm climate.
heat soak is a bitch.
I'd say go for it all day if you were doing a 200 hp d-series or 225 b-series, but not for 350.
PWR get my vote.
2078287
20" x 7.8" x 2.87"
720
MSRP $450
if you want to keep your bumper support
20105287
20" x 10.5" x 2.87"
900
MSRP $495
if you don't. (i cut mine)
MSRP = high. you can score it for 375-400 all day if you look hard enough.
IMO, the 200 bucks is well spent.
