Ls7 upgrade kits, worth the ally flywheel?

[bigfatnick]

Hi all.

I know this has been covered, i've got a bit of info from searching but pistonheads without a proper search feature just isn't as much fun. Anyhow. I'm doing a euro roadtrip in the summer and my current clutch (despite only having 28k on it) doesn't fill me with confidence.

So I guess a spigot baring and LS7 clutch is my only option. Question is, looking at the monkfishs website do i go for the standard fly wheel, or one of the two lighter flywheeled clutch kits (which appear to be the same, just priced differently, is the more expensive one just even lighter?).

So, lighter flywheel or not? Buy in the uk and risk it and attempt to buy from the states (not that i know what i'm ordering. Also, I have a competent person to fit it for me, but he's always busy. Recommended places for fitment. I don't mind driving to milton keynes for it, but i'm in leeds, so if anyone knows anywhere from round here i would be appreciative if anyone knows any monaro experts in my area.


Ps - its a 56 plate LS2 Vxr.

Thanks muchly!

PS, is "clutch sticking to the floor syndrome" where you give the clutch hell and it gets really firm and doesn't seem to return as far and goes rock hard? Or is that something else (like the clutch pedal actually staying stuck flat to the floor)?

Thanks again.

PS, i love my new monaro, i got thumbs up from a random in a hyundai coupe this morning on the motorway, i've not had a single negative comment, even the bloke i met with a ferrari 458 loved it, and had a random chav woman tell me to rev it up in a residential street this morning, Neighbours love wortec!

I'd ask Monkfish about the options myself.

However I fitted a RAM aluminium fly wheel with an LS7 clutch kit on my LS1 as that combo kept the mass similar to the standard LS1/LS6 clutch assembly. I knew there were lighter flywheels such as a Fidanza one but I was happier with the RAM fly wheel as it's still very robust. 3 years and lots of abuse have proven this.

Is the clutch fluid in the reservoir dirty? If so change that first to see if that cures it, I used to syringe the fluid out and replace with new stuff quite regularly, but don't empty the reservoir completely or you will get air in the system I think, this was in my ls2 vxr, much cheaper than a clutch, hope this helps

Easy one this IMO. Yes. Limiting rotating mass is worth (the effect of) about sixteen times what you are taking off the flywheel.

Flip side is that stock FW is good for initial bite and take off and "stall reduction properties".

I went for this, the ally FW from monkfish.

I found the following:

Car revs quicker
Due to above, slightly quicker gear change
Absolutely zero problems with stalling it, these cars have too much torque to stall
No problems with 'launching', they're traction limited anyway, so unless you've got drag radials on the back, I can't see a disadvantage.
Absolutely no clutch sticking problems whatsoever since the change. Used to do this a lot, and fairly soon after fluid change
Clutch pedal felt slightly lighter than stock, although may have just been the difference between an old LS2 and new LS7...

In essence, I'd say go for it, I've seen no downsides, given the difference it made if something even lighter came up cheap I'd go for it.

Oh also, if you have a huge lumpy cam, a heavier flywheel can help smooth out the idle I believe?

A friend with a C63 always uses Tuning Developments (http://www.tuningdevelopments.co.uk/)

I personally have only been there for a dyno day, but looking at what they had stored up to work on etc. they aren't just some guys with hammers, so should be more than capable of doing the clutch / flywheel etc.

They'd be happy to supply or fit from what I've gathered, so may be worth a call. They're in Warrington, so an hour from you.

Otherwise AAS are a very known quantity, they're in Newcastle though so a little further.

Thanks mate. Think i'm gonna do it.

Surely the best part of having a lumpy cam is listening to it barely idle.


Will have to order it after payday!
