JWT vs Southbend Clutch/flywheel set-up

UPDATE: I went with the Southbend Stage 2 daily with 14.5lb aluminum flywheel and couldn't be happier

Hello man, how is the FI project? Can you give us more review on the Southbend Stage 2? Thanks

O&G · 03-19-2014, 04:54 PM

Been running JWT products in my VQ's for over 8 years, Awesome! Everyone on here seems to lean towards Southbend, either way, they both have great reviews and customer service.

I just upgraded to the southbend stage 2 daily from ZSpeed with the 19 lbs steel flywheel and cannot believe how much better it drives. Now just need to put some break-in miles on it before I can really test it out.

Also I have it combined with the RJM clutch pedal which I also highly recommend. Lets you dial in the engagement zone right where you like it!!

break in is over rated IMO, do some heat cycles and some light stop and go traffic and let it rip, just pulled my clutch out after 25k hard miles, the last 1k boosted and it looked good, I upgraded it to a better disk, one of the daily disks with a higher TQ capacity.

So JWT vs Southbend vs SZ, which kit is the best? I concern more on the drivability, performance and durability. I assume all the lw flywheels will have some noises. I am cool with that.

And what's the differences between the Southbend stage 2 daily and stage 3 daily. I know one rated 450 and the other rated 550. But how's the drivability between the 2 kits?

I've had both the JWT and Southbend stage 2 setup. They both pretty much felt the same, and drivability is pretty much just like stock. The only time I could really tell I had an aftermarket clutch was when I would power shift or dump the clutch, it grabbed a lot harder than the stock setup. I also had the Southbend lightened flywheel. It was 22lbs (stock is 31lbs).. it was a little noisy when sitting at idle, but while you're driving you won't be able to hear it. Plus it revs up so much faster than the stock crap.

Great info as always.

Do you know how heavy is the JWT flywheel? Is it aluminum or steel? Also are both JWT and Sounthbent stage 2 kit can hold similar amount of power?

I've had the JWT aluminum flywheel, it's about 16 lb.

Now I have the Southbend steel flywheel, iirc that one is about 21 lb.

i got the same set up no complaints here

Merv · 01-03-2015, 10:39 AM

So from the looks of it,there's about 3 options for aluminum flywheels. Of coarse the lighter the better performance wise. I'm assuming the heavier you go,the less "chatter" you get because of more material to absorb the vibrations. So anything lighter than stock is a win,and with the heavier of the aluminum flywheels would be more street friendly?

I did a new CMC, the zspeed CSC, and stage two daily clutch and steel flywheel from south bend. I love it! Revs noticeably faster for me, but the chatter isn't terrible. I honestly think engagement is smoother than my stock clutch as well. I also have some peace of mind now that I've been autocrossing and tracking the car on a consistent basis. I switched it all out due to CSC failure around 35k miles.

Zoren 370 · 01-10-2015, 09:07 AM

So you say it accelerates faster now? How much labor cost you to install everything for your clutch flywheel csc cmc etc.?
Thanks

That's good to hear.

Do you know how much power the stage 2 can handle? Coz I might go boost at some point. That's also a main reason I want to upgrade the clutch.

Anyone has experience with the Southbend stage 3 daily kit? How it drives?

PharmDZ · 01-10-2015, 11:03 AM

Stage 2 daily is rated for 380lb/ft. I'm staying NA so that's plenty for me.
