MR2 MkII 3SGTE - lightened flywheel thoughts?

It's time for a new clutch and was thinking... lightened flywheel.
I'm running a very stock 3SGTE (well... chipped and K&N - counts as stock to me) and will be driving on the street only.

Anyone got recommendations? I'm leaning towards HKS, just because one-piece chrome-moly will probably be more reliable than multi-part aluminum and steel.
I'm also only looking to reduce flywheel rotational inertia by 20% (or maybe a bit more) to make the car a bit more fun to heel-and-toe.

Thanks!
Bob

PS: This is my first post here, but I'm not exactly an automotive newbie

Oh absolutely - the question was which lightened flywheel - for a street-only daily driver...(?)
I've put lightened flywheels into a good number of bikes - both for street and for track - and it's clear that, although almost no flywheel is a good thing on the track, you need at least a bit on the street.
So I'm only looking for some reduction in inertia.
A further complication is that you can't just compare weights - it's the distribution of the weight that matters (for instance, the old single cylinder Guzzis had a large diameter flywheel that was pretty light but had a huge amount of rotational inertia because the weight was almost all out at the rim).
Thanks!
Bob

which depends on your wallet....do u go out and spend the money and get an hks or jun flywheel....or spend less and get a fidanza??.....i highly doubt that the hks or jun is much better just b/c of its name and price....personally...for my car...i'm going with hks....all things hks does it for me....

It's usually better to get the same brand for both your clutch and flywheel. Because it makes sense that they would test their aftermarket clutches with their aftermarket flywheels. So there is a much better chance that the system will work more efficiently if both items are from the same company. Just my thoughts.

I ordered the HKS one ($408 with shipping from racerwheel.com).
Will probably just build with otherwise-stock Toyota parts (I've had some bad experiences with motorcycle "race" clutches and figure the stock stuff should do me fine).
Will report back - especially if something doesn't work.
Thanks for the input!
Bob
