Up graded clutch

Myself and quite a few here on mid power single turbo's have had excellent experience with the Southbend DXD. It's very reasoabably priced too.

 

However:

 

stock will handle BPU levels fine dude.

 

Is absolutely right, unless your current clutch is goosed or you're using it for drag racing, the stock is fine for BPU.

 

If it is no good then it's worth replacing the flywheel at the same time.

Order direct. I can't recall prices, but they are quite reasonable.

 

It might be worth contacting Dude at AFR as well, I think it was AFR that had some trade contact with Southbend.

 

I Ordered my Souhbend from Dude at AFR, and is currently in my car just now. Pretty good clutche so far, but not had time to give it some real abuse due to the weather. :(

I have one, i know it should hold the power longer as well as the feel is very very close to stock (I can't fell a difference, even though CW told me there was..)

 

I *think* the CW clutch is in the 6-700£ region IIRC

 

What Kind of clutch does Chris use??

 

I picked up my southbend for like £500 new, and this holds well over 750ftlbs. :D

I'm pretty sure CW's is similar to the RPS street ones. Stock OEM clutch but with a modified pressure plate.

 

Had a CW clutch in mine now for a few years, drives same as stock. I'm pretty sure Chris prefers to fit the clutch himself rather than just supplying one though.

Nowadays I am happy to do a supply only, see below for details, thanks.

 

 

I use the stock, brand new driven plate, as it is correctly

balanced, doesn't judder and will hold all but mega torque

highly modded engines or cars used for drag racing.

I modify a stock brand new cover to give more clamping force.

The reason I tooled up to do these is some of the aftermarket

US clutches I have fitted SEEM to be built from used cover

assemblies with reground friction surfaces, and a stronger

spring. I have had hellish trouble getting these to fully

release, because due to this seemingly thinner cast iron

friction face, the geometry of the clutch goes to pot, and

being a pull type clutch (the hydraulics pull the bearing

away from the engine, rather than the more normal push type)

it is a lot harder to effect a cure.

 

For 455 pounds, plus VAT you get a brand new driven

plate, a brand new modded cover, and a brand new release

bearing. I would rather fit myself so any complaints are down

to me, I see too many clutches juddering due to someone without

the right gear trying to fit them, or clutches fitted to patently buggered flywheels.

 

 

Toyota use a dual mass flywheel (the flywheel is in 2 parts, an inner and

outer assembly, damped in the middle) which is now showing signs

of wear causing a lot of rattle when idling or on very light

throttle openings. For God knows what reason they are charging

about 270 + VAT quid for a new one, they look more like they should be

over 500 to me, but don't say anything :-) So if the flywheels

old enough or abused enough to be scored it's best replaced.

If pressed I will sell the clutch kit, which includes a new release

bearing for a 3rd party to fit.

 

Fitting by myself will cost £175 + VAT.

If you are only ever going to run stock turbos on the street then the smoothest, quietest and easiest clutch to use is stock Toyota.

 

The only reason to 'upgrade' would be if the clutch cannot handle the power.

 

If you do want a bit of extra 'bite' to the clutch TRD do replacement friction discs and clutch covers.
