Default McLeod RXT or Monster LT1-SC

These are the two clutches I have narrowed it down to if I do decide to stay t56 and not go auto.

Anybody have any good or bad experiences with either clutch? I'm going to be making around 800rwhp with nitrous in a 2900lb foxbody and wanted to get opinions on which clutch people are having The most success with.

I will say right now I am leaning towards the LT1-SC because I hear the RXT doesn't like to be slipped at all.

I've slipped the crap out of my RXT to get down a greasy track at 3900lb race weight and ~700rwhp and it never skipped a beat. Part of the reason I went with it....the copper ceramic friction material can be slipped and not glaze over. I pulled it after a season to inspect while I was freshening the trans and it looked brand new still. I've added about 300hp this year....we'll see what the RXT can take!

Monster makes kick *** clutches with top shelf customer support, so you can't go wrong with them either.

Drove a gt500 this past weekend, had an RXT in it, even with a clutch cable, it felt amazing. I wouldn't hesitate to go with one.

Default Monster lt1-sc

I am a fan of monster but may try a McLeod next. I put the lt1-sc in my car and it had a vibration. Paid a shop $400 to pull the clutch out sent it in and they said it was within spec but it was out 9 grams. They went ahead and balanced it to 0 and now it's smooth as can be. I asked for help with the bill for removing the clutch and I was told to email the owner Steve. Ehhh I'll just buy a McLeod next time.

Have you emailed Steve? I'm confused how you think asking to email the owner, which is the guy who will say yes or no to your request, is bad service? Also, if you buy a McLeod you have to pay to balance it with your flywheel. We re-balanced it for you for free...

I have the rst and have seen the rxt in action in a friends cobra. Both clutches drive extremely well and have a lighter pedal than stock. He's had no issues with slipping his rxt in traffic. any ceramic performance clutch isnt going to like being slipped forever, thats just a trade off you have to make.

Since I am local to SNL I will most likely go with Monster for my fbody.... However, My
C5Z is making 718/732 and my Mcleod RXT doesn't skip a beat... It is set up for the 1/2 mi racing and I beat the **** out of it.... Drives better than stock!

Very difficult decision for me.

Do you guys know exactly how the lightweight flywheels work? Are they as bad as they say they are driving on the street?

How much power can be picked up going to the lighter flywheel?

I run a 15lb flywheel on mine. Drives just fine. Total clutch weight is 38-40 lbs if I remember.

McLeod makes a 15lb flywheel or you have an aftermarket flywheel?

A lightweight flywheel will make any clutch feel more aggressive. The severity of this will vary depending on how aggressive the friction material is.

As far as power goes, you will only gain a small amount of HP with a lightweight flywheel. The main positive of going with a lightweight setup is the RPM's will be more responsive, which is great if you do a lot of Rev matching (I.E Road racing).

For street driving we usually recommend a heavier setup. Feel free to give us a call if you have any questions. (817-750-2000)

If I could show you the pictures of the garbage part McLeod sent me 2 times, you wouldn't buy anything from them.

I've got the RXT. It is a little tougher to slip but does a light feel and seems really strong.

I have the fidanza 12 lb in mine. whole assembly is 33-34 lbs. I just taught my gf to drive stick on my car and shes never driven one in her life.. hows that for a testament? when I had the cam in the old setup it had a lot less torque down low but i could still easily take off without using the gas if i wanted to.

i wouldn't recommend a heavier setup if you want to win races. in my expereince the only place a heavy flywheel helps is getting out of the hole. at the redline its just more mass the engines has to try to overcome, if you can launch the car correctly you will have only benefits. plus with my fidanza when i pull it to swap the clutch i just remove the friction center and go bolt in a new one for 40 bucks.

Looking for info on this as well, for a DD-able 700ish hp 3700lb car. As well as the mcleod/monster debate, how do you guys feel adjustable vs stock master cylinder on the twins? Necessary, beneficial, or no point?

Edit: Also, dose the ACT T1S-G05 weigh in here anywhere? Seems to be a similar clutch.
