Flywheel lightening, Beds

Not local, but only in Essex/Sufflok area:

A mate of a mate works there, they do good work and i'm sure if they haven't got one on the shelf they could advise on machining yours.
Had one of there's on my old Astra C20XE, excellent mod, lightened flywheels rule - will be getting one on the MX5 next year when it goes SC.

I'm not really aware, no. I'm not aware of many things!
Lightening the flywheel will cause it to rev more freely, sap less power and generally perform better when you're thrashing the living daylights out of it. As they're a track inspired idea.I'm not really aware, no. I'm not aware of many things!
Negatives are general use related such as: runs out of puff easier on hills, round town will be revvier, so less calmly driven etc.
As for the flywheel you need, IME you'd be wise to contact:
POWERTRAIN DEVELOPMENTS/PERFORMENCE (cant remember which they're called) as they have rover patents IIRC
or
JANSPEED as they do plenty of MG/Rover goodies. I got manifolds and other such items from them for my ZR.
what caused you to want a lightened flywheel?
Thanks Kev they list one on their site, I've pinged an email over.
The downsides don't seem too bad to me. I thought about one as I'm about the replace the clutch, there is not a great deal you can do to the KV6 for cheap gains so I thought while I had the clutch out it may be worth dropping q better flywheel in.

fair play then mate.
Personally, I'd be also uprating the induction and exhaust system.
ITBs? custom manifold, sports cat, downpipe, stainless system and then suitable silencing.
That's where your best gains will be.
I got my 1400cc ZR to around 125bhp at 6500rpm. which wasn't bad on a standard map.
If car's low miles then injectors will be ok. As mine had rocked up 90,000miles (70k in 2years with me) I wacked new ones in, which helped A LOT as well as bigger inlet manifold.

For what's it's worth, i didn't experience any of the downsides described above on my Astra. Ok so there's a bit of difference between a 2.0 4pot and a 2.5 v6, but not so much as to make it significantly un friendly in normal driving conditions.
I think a lot of that is down to how much lighter the flywheel is though, when you start looking at the ones that resemble swiss cheese - then yeah i think that might cuase problems. But you don't need to go anywhere near that radical on a road car to notice the gains.
