I am looking for the most street friendly clutch for a daily driver that I can find that will hold my power levels. I do not go to the track, and honestly 90% of my street driving is very lazy 'grocery getter' type driving. How are the street manners of the LT1-SC, and how much streetability do you give up over the base LT1-S??

The LS7 clutch has been fantastic, but it's slipping at 700 RWHP/600 RWT. I was really considering the LT1-S as it seems like the perfect clutch for me, but I'm right at the edge of it's rated limit and if I turn up the boost I may be back in my current situation of a slipping clutch... so the LT1-SC is the next choice.

I have had Monster stage 2 and 3 single disks in the past but took them out becuase they both had too much chatter for a daily driven heavy CTS-V. After 5 minutes of stop and go traffic they would just about rattle your teeth out pulling away from a stop.

Any advice?

 

Although I can't speak for that clutch, I can tell you the street model of the act twin works fantastic and has a softer than stock pedal if you get the entry level one. It also has full support and is rebuildable.

 

I would go McLeod RST and never look back.

 

Our DYAD clutches are designed to handle up to 1,300 ft.-lbs. of torque while also engaging smoothly with a light pedal for street driving duties. The floater also has bushings in it that sit flush on the flywheel to reduce chatter.

Here's our R&D chief Will Baty talking about it at SEMA a couple years ago:

 

Mcleod rst. I have personally installed more than i can count. If you install with new (gm not gimmicky others) hydraulics, it will be perfect every time. Itll slip a little if you want or grip hard too. Works well for cams that arent tame under 2k for pedal modulation. The best street clutch ive ever sold and installed. Easy. No bs. no shimming. no run around on warranty or emails saying 2 weeks 2weeks. They are ready to go!
PLUS they look like a clutch Iron Man would promote! And we are running a 10% off special right now too!!
If you have any other questions on them or any other clutch that is similar, let us know!

 

The ACT which we sell are great clutches. I would personally recommend the RST clutch though. Both nicely streetable and proven performance and they do not have to sell warranty for their clutches like other companies because they rarely have issues with their clutches.

And do not forget RAM. Most of our middle eastern customers love the RAM dual disc setup. I do not know why it is so popular over there more than over here.

I bought an early RST, wasn't a direct bolt-on at the time; I returned it. McLeod said street twin would fix bolt in issue, I installed and toasted 2 in several hundred miles and both were very off balance when I had them checked. Pretty disgusted with their product. I did have a conversation recently with several guys at McLeod and they made it clear things have changed more recently and that all previous issues have been resolved. I was invited to try their product again. I'll consider, they were very receptive to my criticism and understood my pain at the time due to some internal issues. Very stand up of them to be so honest IMHO.


The RAM has always been interesting. I only heard of a few early failures, possibly due to stack height. Their twin seems very nice as well.

You guys carry an awesome selection!

 

I've been installing the rst since 09 on vettes,fbodys, and gtos with zero install issues and 100% success rate. So things have indeed changed if what you got was an early one. Their directions had changed a few times but mostly it's: open box, make sure correct side is facing flywheel, bolt on. Then install trans etc. Normal break in will vary. Then have at it.
The Mantic is somewhat of a new player to the game but has excellent design and is used by quite a few big shops out there on s/c builds.
We still have a special running on mantic and mcleod through today.

 

Yes, by '09 they had gotten all changes into production AFAIK. My experience was about a year before that. I Still like the low MOI design of the ACT and the fact that they are local. The mantic is very appealing. I need a new clutch soon and haven't decided on which just yet. At any rate, you guys have an awesome selection.

OP, my apologies for pulling this off of course.

 

Give us a call, or shoot Jacob@monsterclutches.com an email, and we can go over details.

 

Interesting thread, I'm also shopping around, car will make around 450rwhp and mostly street driving/cruising. Def need something with good street manners...

 

Interesting. I had all but ruled out the RST due to several reviews around chatter on the street.

 

I've been running the RST since 2012 and it has performed exactly as advertised -- good street manners, stock-like pedal feel and it's held the power (630+rwhp) without any trouble.

Zero issues with chatter for me.

 

The monster might be even better with its self adjusting pressure plate honestly.

 

Alot of them dont use self adjusting PP. The ls7 clutch uses that same style PP and it has had quite a few issues.
That is also close to the same design you can get from your nearest auto parts store for less.
I've seen arguements either way on the issue and i am not biased one way or the other.
The RST or MANTIC get my vote. Check out the mantic with the ER2 PP. The design is pretty trick.

 

go with the monster they are the best in the business. I love my lt1-r

 

Sure sounds biased... and considering you follow it up with what you sell, that in and of itself is biased.

The LS7 is an older style self adjusting piece, we've gone over the technical differences in that versus the newer design we use in numerous posts. The newer is far improved, not only that it is far superior in lift/release and high rpm shifting.

If you think this doesn't work ask Ray, his car has gone mid 8's with an off-the-shelf LT1-R.

Good luck with your sales.

 

Just an FYI -

The RST compares to our S twin, though our S will last longer, hold more, and will have no high rpm release issues. Also, you can abuse/race our S and the warranty is still good - we encourage it.

The RXT compares to our SC twin, though again the SC will last longer, hold more, and will have no high rpm release issues.

The R twin will hold more than all of them, has gone mid 8's, and will take abuse like nobody's business.

Not to mention, all Monsters include a 1 year warranty - that's 4 times longer than the other guys.

 

Dont point your finger at me when you are selling nothing but your clutches. Biased? Come on. People can spot propoganda. We offer a VERY large selection of clutches. I recommend what i would personally run and not the one that has the highest profit margin. Even before i sold yours I hardly recommended them. Even when i did id rather recommend something else. You dont remember complaining that i wasnt recommending your clutch over the mcleod multiple times? Zero issues with mcleod rst rxt over 5 years. Even custom make ones in 05 vipers. Whether it be warranty issues or customer issues or install issues. We recently started with Mantic but ECS has huge success with them. And they are one of the leaders in the LS S/C niche.
You forgot to mention the Original Street Twin. What does it compare to?
How can your newer design vs ls7 be so different in a self adj PP if you get them from the same place?

 

Propaganda? Do you know what that means? You're saying I'm misleading people into purchasing my product? How was anything I posted misleading or false?

It's advertising and sales, we're both doing it. Technical data and facts are what's important and I think you do a decent job of stating those. That said, don't say you're not being biased when you clearly are. I have no issues with you pushing what you sell, that's not why I posted a response to you.
