After my last mapping session the OEM is starting to give way at 411bhp and 375lbft with 54k on the clock. So shes held out well.

Need a clutch that will cope with approx 450bhp & 400lbft+ but for everyday use.

I'm getting myself confused with looking at kits. Some do this, some do that etc.

Most of the ones I have looked at are for 5 speed but within price bracket.

So in a nutshell need to know the following...........

What clutch is suited for everday use for similar feel to the OEM pedal for my goal.

Has anyone got good feedback of trying both Organic and Paddle? I'm guessing for everyday use Organic would be better suited or have I got this mixed up?

Is it the Paddle which is best known for ON or OFF biting point?

Would you get judder unless you go for anti-judder etc?

Noise. Some give the rattle and chinking sound before clutch is put down. Is this mostly on Twin and Triple styles? The noise doesn't bother me as I won't hear it over the RCM Team Ice system anyway but got to ask.

What comes with everything I need for install. What should I be getting in a kit?

Most importantly Price for a good bit of kit that won't last 10k and need replacing?

I'll be looking at fitting this myself as money is very tight at present so cannot afford the labour costs sadly with my misses still off work but with someone watching over me.

Sorry it's a lot to ask of you all but need to get my car back up and running ASAP for work etc.



Cheers

I've got a helix twin plate fitted to mine & am running nearly 500bhp & 585 lbft of torque. the pedal feel is very light, probably lighter than stock. No rattle either.

Helix do a single plate reated at 450lb/ft.

Also got a Helix twin plate. Light feel as has been said, and easy to use - you don't really know you're using a twin plate

It has no springs in it though, so there is some driveline judder and therefore gearbox noise at low rpm/higher gears but it has improved dramatically as it's bedded in.

The bite point on (probably just one of the plates) of mine is only a fraction of a millimeter off the floor. No one else has reported this problem, and Helix say it's behaving normally, but it was a PITA as it made the car easy to stall when pulling away. But increasing idle to 900rpm, and putting 12000 miles on it, and now a) I've got used to it and b) it's improved anyway. Possiblty had a few high spots on it, but thought I'd mentioned it.

I have an Exedy twin plate clutch and I really struggled to get on with it at first as I found it really difficult to pull away smoothly without juddering or stalling.
However, it turns out that my problems were due to a dodgy map !! Since having the car remapped by Zen Performance the clutch has felt absolutely fine and no more difficult to use than an oem clutch, although it does suffer slightly from the driveline judder described by Tim in the above post.

Great input guys. Thank you.

Nice to see different brands popping up too.

KEEP THEM COMING.
How long will it take a clutch virgin to fit?

Bedding in time will vary I assum from brand to brand I guess?

The 2.5 OE clutch is reputed to be able to cope with those everyday figures.


Plate (30100AA920) is £104
Cover (30210AA670) is £115
Release bearing - Exedy one off Ebay £30
Spigot bearing £10 off Ebay

Total £260 for a clutch kit able to take 400+ lbft!
A bit cheaper than an Exedy stage 2 and judderless (if flywheel is also ok).

my standard clutch held for 12 months with 530bhp and 500lbft.

I now have a sachs clutch fitted and the feel is identical to the standard and I use my car everyday. The car is now running 580bhp and 530lbft.

AP racing organic single plate has held up fine against 450bhp/380ftlb in my 6 speed P1 even though it's actually a 5 speed flywheel and clutch - so a 6 speed version having a larger diameter should work well. OEM feel

I see your point. Thanks for the input. Trouble is down the line if this isn't the case then I am back to where I started.

Like the price bracket too. Food for thought though I guess.



I have heard where people have got away with putting 5 speed clutches in a 6 speed. How does that work?

Been looking at Mark's clutches at Lateral's site came across this for 5 speed Exedy Organic 230mm Pink Box Clutch Kit For Subaru Impreza 5 Speed. With The FD08H1 Disc .
If you can fit a 5 speed in a 6 speed what is this clutch rated to anyway?

Also Mark has a Exedy Pink Box Subaru Impreza 6 Speed Organic 240mm Sport Clutch Kit but is only rated to 400bhp.

Whats the different between a 240mm and 230mm?


Holy ****. How you manage that?


Contacted a few sellers on eBay regards there kits. Some of the replyd I got were shocking.

I asked about ratings. One gave me a reply of "Not sure whats it is rated to. We have tested this fully so should be ok in your car" Right!!

Also seen the one on Bob's website. Exedy 240mm Organic Clutch Kit - 6 Speed Impreza Turbo STi anyone know what this one is rated to?

If I am getting these bits would I need a new flywheel too?

API are doing a group buy at the moment on their own modified Exedy clutches, apparently they are rated at about 430/430.
6 speeds usually require a replacement flywheel.

iTrader: (2)

why do six speeds usually require a replacement flywheel? do they really get that battered if used as a daily driver or track car?

It's not solely related to 6 speeds it is good advice for any new clutch. Just using them over the years let alone ABusing them, creates blister marks and heat cracks.

Anyone supplying a clutch, will tell you that it very difficult to offer a warranty on a clutch that may not have a chance to settle and grip because the flywheel face is in poor condition.

Many customers have been to APi and waited whilst we fit and are surprised to see just how bad their flywheel is, once we get it off. No one has yet refused to replace it, once they see and understand how bad they actually are.

david whats the price of a flywheel and clutch from yourselves?

cheers

Fat Boy

5speed set up goes straight into 6 speed box, a 6 speed clutch does NOT go straight into a 5 speed box, because of the increased diameter. Some people have managed it but only by grinding away part of the bell housing which isnt wise in my book

Cheers for the info folks.

So need to add a flywheel on the shopping list too. Bugger.

Butty, will look into the 2.5 STi clutch. Should be interesting.

The stock STI 6 speeder clutch lasted for near a year of dragracing in my car with about 400bhp!
Now I´m using a AP racing organic single plate as well as Fat Boy, but the 6speeder version with a lighter flywheel and it´s great!
If you use another pressureplate than I do (heavyduty), you will have a lighter pedal feel too!

Sorry - I took a long weekend off and this has only just popped up on my radar.

Flywheel and clutch for which car ??
