Default Spec 3+ vs LS7

I really need a new clutch soon and I was wondering which you would prefer. Please state your reasons for your vote. Also what sponsors would have the best deals on these clutches?

How much power are you making now and how much honestly will be making with in the next 12 months?

I have the same delmia but basically it boils down to if I did a clutch, I would do both bearings, the pilot and throw out, and a new GM slave, stock clutch master due to the year, your going want to update your hydraulics to 01+

I priced spec 3+ with their steel flywheel and its 750-800 bucks with shipping. Scoggin Dickey have the kit for 399. The bearings, slave, and clutch master are relevent to both. The stock feel to me is a plus and will handle your MSD wires etc etc.

I plan on a Procharger and I will still use the clutch until its dead, then consider a 3+ since I should be making 475-500 rwhp

I Have about 120 Mi on my new Spec 3+, I got a new Spec billet steel flywheel and it was about 800 bucks. I was surprised the kit came with its new pilot bearing and a new slave cylinder head. Clutch feels good has some nasty chatter on some take offs, and on others is as sooth as stock, It seems to be grabbing like a **** I am really liking it. Btw the pedal is wayyy lighter than my Ram HD its a little heavier than stock but not much.

it's a twin clutch system. I believe every company has them now. it's usually the most expensive but IMO it's totally worth it. smooth engagement, no chatter, holds tons of power.

You would have to check with the sponsors, some of them sell clutches others don't. To answer your question, they usually run from 1100 to 2000+

I wish I could actually afford that. I think I'll go with the cheaper LS7 clutch kit.

for the money the LS7 is a good choice between the 2, u don't need something as agressive as the 3+. my 3 stayed in the car for about 20,000 miles daily driven and I got so sick and tired of it. same with my Ram HD. Now I have the Ram twin disc and I absolutley love it. u cannot go wrong with the LS7 for being a good single disc but if u do choose to go with a twin make sure it's organic style discs...no puck style because u will get chatter and harshness from it.
