Well after my clutch slipping issues I had a long chat with Stuart at Mardi Gras Motorsport and cannot say enough good things about them - know there stuff and very helpfull Anyway I had a choice of; std new clutch plate uprated organic plate (not much improvement over std, torque rating) race paddle disc The cover plate is very strong on the M32 (astra vxr box) and there is nothing stronger currently available and no real tried and tested kit to loose the dual mass So hopefully the paddle will do the trick (pending getting a cover delivered today!) Pedal should be just as soft but bit more bite as with paddle clutches though they can recover from heat issues unlike the organic type Stuart if very confident it will not be that much different to std due to std cover plate (M32 have solid disc) If anyone fanicies hosting a pic I can email one (can't upload from work ) DG

IMHO I would be careful putting a paddle on the M32 as the synchros are quite weak and they have failed due to aggressive paddle clutches in the past. I'm using a Helix which is rated to 300ft lb and I'm making 301 @ the hubs and it hasn't missed a beat.

Chris stop making me worry It may be that a new std clutch would have solved my problem, not taken the old one out yet and may just be worn? And suspect the helix organic would be upto the job, I had not had any feedback on syncro problems or may have played safe with the organic option. May take it easy on full bore launches (or not ) just figured while I had the box off to put the best I could find on so in the future if I go for more power it is one less thing to worry about.

With the dual mass still in place you might be OK. I removed the dual mass on mine so there is no shock absorption and really didn't want to add a paddle clutch into the mix. Also, if you are going to be doing some heavy track use get some Redline Heavy Shock Proof gearbox oil. I was using the Silkolene Syn-Tran 5 but this caused the synchro's to crunch slightly when very hot, changed to the redline and it's been perfect. For me, so far, the M32 has been terrific as a track box, very very pleased with it.

[Duncan VXR]

Thanks for that Chris Just ordered yesterday some fresh Silkolene Syn-Tran 5 - not had problems yet but this will be the 1st summer track days in Europe and obviously a lot hotter than the uk. Chris I love the 6 speed box, ratios feel great and overall a nicer box to use DG

[cnrandall]

Don't suppose you ordered it from Opie? If you did, they also do the redline so may be willing to swap?

It was, going to give them a call now

Will update this thread after to let you all know how it compares to oe

What I should also say is that I've ditched the dual mass flywheel and replaced with a solid one. It's not the lightest but it's still massively lighter than the dual mass and hasn't caused any problem whatsoever.

[Duncan VXR]

Did think about trying to loose the dual mass but did not find much available, forgot to stalk your good self Job for next time, at least keeping it should save my box from exploding

Where can I get the Helix (disc only) for my 2.2, and hopefully for a reasonable price? Seems to be bordering on £150 where I can actually find it.

Well SOOOOOOOO glad this job is getting done at Liam's - he is doing most of the hard work and I am just helping Cover has loads of hot spots and not fully flat (have new one) plate is nice and shiney lol and a few cracks. THe dual mass has the hot spots also but not out as much. Waiting for Terry to confirm which way round the plate goes as it is different each way but does not seem to matter which way?????? Replacing dual mass is a no no due to cost but see what Terry says tomorrow - may get is machines? Or go the whole hog and got solid flywheel :O Massive thanks to Liam for the work - he is a bloody good lad! DG Got pics but cant upload

I might have a dual mass in the workshop...

[Duncan VXR]

Chris, I was speaking to Duncan this morning is it in good condition?? Found out which way the disc goes - side that sticks out further is gearbox facing Transpires that Terry has a replacement kit for the dual mass lol Terry did seem to think although fine for driving in traffic you do not want to slip the padel clutch too much or it will wear a lot quiker time for learner driver traffic driving lol DG

[Duncan VXR]

Well a MASSIVE thanks for Liam at MMG for his help on my car. Been on his ramp for a week long story short the car is back together had fun bleeding the thing but the clutch pedal just does not feel right. Found if you change gear slow it is fine and does not slip but try to change gear quick and the clutch has not disengaged fully and slips?? After some testing / basic theory of the clutch we think it is the intermediate pipe for the slave cylinder that is causing the problem and even though a genuine hose clamp was used it looks like it had caused the inside of the rubber to break up a bit causing a one way valve type setup. Pressing the pedal is fine but when you lift the pedal after half way you can almost feel it slow down and hear a woosh noise. If you press the pedal again before this the pedal goes hard at half way down and cannot be pressed further. We think the fluid has not return fully hence the pedal not going fully down. If you do it slow then works every time. New cover / disc plate / dual mass flywheel and slave cylinder so notsure what else it could be???? Anyone else had this issue? Tried to make a new braided hose replacement yesterday but could only get the 10x1 concave connection, for some reason vaux decided to use a 12x1 concave on the other end (o a common size) so off to Silverstone 1st thing to see goodridge and hope they have one Vaux wanted £90 for the oe one and a week to deliver. Not good as I am at hoffmans on Wednesday and track day getting close lol Have to say other than the issues above the paddle clutch feels good and only a slight bit more bits than before

[vocky]

I had a few nightmares with my M32 clutch (thankfully all sorted), I found that by pumping the pedal once whilst the pressure bleed thingy was connected was the best way to bleed the clutch master cylinder.

[Duncan VXR]

Yeah tried, old school method. One man bleeding kit and pressure bleeding. Also even tried back bleeding Fingers crossed its sorted soon got to love midengineed carsfor bleeding clutch lol DG

If you do want to try another hose mine is spare for the moment, if it fits of course.
