Manual Transmission - 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?

Anyone???

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 mofo I am really liking it. Btw the pedal is wayyy lighter than my Ram HD its a little heavier than stock but not much.

buy a twin disc and call it good, u will LOVE it I promise. it's worth the extra money

Yep, Spec 3+ came with New Pilot Bearing,Throw out Bearing, and alignment tool.

What is a twin disc?

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.

hMmMm....What sponsors carry this? What is the usual cost of a twin disk?

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+

A number of our dealers are sponsors of this forum. Including: WS6 store, T56Rebuilds, GMMG, Tbyrne, Livernois, etc...Let me know if you have any further questions. Thanks!!!

I guarantee u will not be disappointed in a twin disc, it's worth the money. do it right the first time.

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

do you going to install it by yourself ?

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.

do you going to install it by yourself ?
Yes, I will be installing this by myself. Is it recommended to change the hydraulics too?

since u have a 99, yes. u should change to a 01-02 slave and u might as well get the adjustable master also and do the drill mod...not too much more money. if u don't do the master PLEASE replace the slave.

I plan on getting a spec 2+ myself and a new GM slave, since im only going to be cam only and bolt ons ........im still undecided on the flywheel.

Speed Inc sells both the ls7 clutch and the spec 3+

Hey SS smoking where in the bay do you live? your car looks pretty clean, let me know if you need any help installing the clutch, me and some guys from my car club can roll through.

My clutch feels like sh!t when i shift so i think is time for a change, I have never done it before so... I can assist changing ssmoking99 clutch also, cause it will be good to watch and learn and give an extra hand in the process.

So the LS7 clutch kit doesn't come with a new slave? Or do I have to get the OEM 01/02 slave? What about the hydraulics? What is the master and what does an adjustable master do?

where do you live?
im located in south cal, Calexico, Mexicali Mex. if you see it by the other side

i was looking for this also and seem like the slave is cheapo like 24 bux from speed inc .. and theres a groub buy whit mcleod hydraulics if i remember correctly

Hey guys, I was told awhile back that they don't even make the earlier model slaves anymore. This was awhile back too.

i have a spec 3+ in mine and love it, after proper break in i have no chatter, and it holds 5k dumps no problem, we will see if it will hold the 402 with a 150 shot on her this summer.

Is there a clutch that is under 600 and can hold a lil more then stock power and last as long as the stock one? My car needs a clutch it has 58,000 starts grabing at top of pedal now and i figure its not slipping yet but i better start saving. i dont want a clutch that only lasts 15k miles that sucks, i dont go to strip alot roll raced a couple times.

^^^ls7

how much power does the LS7 clutch hold?

I just installed my spec3+ with a fidanaza alum. flywheel. I Like it alot. the pedal is alot lighter than I thought it was going to be. It feels almost stock. It grabs fast but its very streetable. I've only got 100 miles on it so far, but so far Im very impressed! Kinda funny how this thread is named "Spec3+ vs LS7" and I just swapped from and LS7 to a spec3+.

don't waste your money on the ls7. if not spec 3 go with something else :D
