Default DFX or Spec 3+???

Both are same price and have mixed reviews, any input on either of these? Will be used for mostly track use and some street probably less the 2K a year. Mid 400 hp/tq at the wheels on ET Street bias ply's and a 3400 lb car. I know I shoould be looking at the Street Twin but I can't swing $1,200 right now.

My Spec 3+ holds up to 1.55 60' times in a 3700lb car. Not bad engagement. Right now I have a bit of a clutch drag issue, but cannot pinpoint whether or not it's from the PP or not. It's been to Spec twice and of course they swear they've measured it and it's w/in tolerance. I've had two of them. The last one was perfect. No issues. Rear main busted a nut and ruined it so then I got this one.

Good to hear, I ordered a Spec but then found the DFX is available for LTX cars. I have till this afternoon to cancel the Spec order if I change my mind.

I have a spec 3+ and it holds the 6k side step on the 150 shot.

Not saying much but it turned the ten bolt into minced meat. The s60 just takes it
